In this paper, karyotype data of the tribe Lilieae in China were analyzed and been superimposed onto a phylogenetic framework constructed by the internal transcribed spacer to investigate the karyotype evolution. Ten parameters for analyzing karyotype asymmetry were assessed and karyotypic idiogram of five genera of Lilieae were illustrated. The re...
Abstract In the present study, the karyotypes of 34 populations belonging to 11 species and one variety of Heracleum from the Hengduan Mountains in China were examined. Chromosome numbers and the karyotypes of three species (H. souliei, H. kingdoni, and H. wenchuanense) are reported for the first time, as are the karyotypes of H. moellendorffii and...
The Hengduan Mountains (H-D Mountains) in China flank the eastern edge of the Qinghai-Tibet Plateau (Q-T Plateau) and are a center of great temperate plant diversity. The geological history and complex topography of these mountains may have prompted the in situ evolution of many diverse and narrowly endemic species. Despite the importance of the H-...
The use of morphological traits as a practical approach for delimiting taxa at various ranks has long been regarded as a reliable basis for taxonomy. However, its efficacy has been increasingly called into question in many taxonomic groups due to its inherent limitations, such as failing to account for phenotypic plasticity, ecologically driven var...
Lilium brunneum represents a newly discovered and described lily species with a limited distribution in isolated alpine regions of north-western Yunnan, China. The recognition of this new species as a distinct entity is supported by both morphological and molecular data. Furthermore, the investigation of this region, identified as a ‘hotspot’ due t...
A new species, Lilium evansii (Liliaceae family), was recently discovered in Yunnan Province, China. Although its range is nearest that of L. henrici, it exhibits the greatest morphological similarity to L. mackliniae, native to the isolated region of Manipur, India, from which it is separated by the vast Kachin Plains. By integration of morphologi...
Although pollinators are often categorized into broadly defined functional groups, much of floral diversity may actually reflect adaptation to different subdivisions within such broad pollinator groups. In Lilium, some species have white or pink flowers of moderate size (the pierid type), in contrast to those with relatively large orange or red flo...
In this study, we describe Lilium huanglongense, a newly-discovered lily species identified following extensive surveys in an undeveloped area of the Huanglong National Nature Reserve in Sichuan, China. This region, located in the Hengduan Mountains of south-western China, is recognised as one of the world’s prominent biodiversity hotspots, providi...
Species boundaries are dynamic and constantly challenged by gene flow. Understanding the strategies different lineages adopt to maintain ecological and genetic distinctiveness requires employing an integrative species concept that incorporates data from a variety of sources. In this study, we incorporated genetic, ecological, and environmental evid...
Lilium paradoxum, a herb from southeastern Xizang, China, has its first complete chloroplast genome sequenced using next-generation sequencing. The genome is 151,814 bp, consisting of inverted repeats (IRs; 26,323 bp), small single-copy (SSC; 17,524 bp), and large single-copy regions (LSC; 81,644 bp). It encodes 112 unique genes: 78 protein-coding,...
Lilium saccatum is a species of ornamental plant found in southeastern Xizang, China. In the present study, the complete chloroplast (cp) genome of L. saccatum was sequenced using next-generation sequencing (NGS). The de novo assembled cp genome was 151,839 bp in length, including a pair of inverted repeat regions (IRs; 26,421 bp), a small single-c...
The former genus Nomocharis, which has been merged as a clade within the genus Lilium (Liliaceae), represents one of the most complicated and unclear groups included in the latter. Research on members of the Nomocharis clade has been quite limited due to the sampling difficulties caused by its selective environmental preferences. In this study, we...
Rubus L. (Rosaceae, Rosoideae) contains around 700 species distributed on all continents except Antarctica, with the highest species diversity in temperate to subtropical regions of the northern hemisphere. The taxonomy of Rubus is challenging due to the frequency of polyploidy, hybridization and apomixis. Previous studies mostly sampled sparsely a...
In this research, the pollen morphology of the Rosa sericea complex has been studied by Scanning Electron Microscope (SEM). The present study aimed to provide baseline information for the taxonomic identification of the R. sericea complex taxa. The pollen sculpture, outline, and aperture show variability in the studied taxa. The R. sericea complex...
Lilium punctulatum, a taxon endemic to northwestern Yunnan, used to be considered a form of Lilium pardanthinum. It is here investigated and proposed for species rank. Morphologically, it is closest to L. basilissum and L. sealyi, but it can be differentiated by its dark red spots on pinkish petals, inner tepals margin shallowly erose or lacerate,...
Background
Bulbus Fritillariae Cirrhosae (BFC) is an endangered high-altitude medicine and food homology plant with anti-tumor, anti-asthmatic, and antitussive activities as it contains a variety of active ingredients, especially steroidal alkaloids. Bulbus Fritillariae Thunbergia (BFT) is another species of Fritillaria that grows at lower altitude...
Taxon delimitation and identification are important in many areas of biology, especially in taxonomy and conservation. Taxonomic treatment is required to establish and justify recommendations in conservation biology for the group being considered. Imperfect and controversial taxonomy can undermine conservation assessment. We studied 71 populations;...
Pollination niche shifts can drive remarkable floral divergence between closely related plant species. The Leucolirion clade of Lilium contains species with either tepal-recurved or trumpet-shaped flowers. The tepal-recurved flowers are bright orange and might be pollinated by butterflies and/or birds. The trumpet-shaped flowers are mostly pale and...

Two Chinese species of lilies are revealed to have been wrongly identified, Lilium rockii R. H. Miao and L. puerense Y. Y. Qian are thus treated as synonyms of L. bakerianum Collett & Hemsl. var. delavayi (Franch.) E. H. Wilson and L. sulphureum Baker ex Hook.f., respectively. The description of L. sulphureum in current floras should be amended to...
The Hengduan Mountains region is an important hotspot of alpine plant diversity and endemism. Acanthochlamys bracteata is a species of a threatened monotypic genus endemic to the Hengduan Mountains. In this study, we present a high‐quality, chromosome‐level reference genome for A. bracteata, constructed using long reads, short reads and Hi‐C techno...
Primula dujiangyanensis, a new species from Dujiangyan, Sichuan of China, is described and illustrated here. The new species is morphologically similar to P. kialensis and P. pengzhouensis, but it can be distinguished from the latter species by dense white hairs at roots, long stolons, smaller plants and leaves, solitary scape arising from leaf ros...
In this research, the fruits and seeds' surface morphological features and their taxonomic significance were determined. Additionally, useful traits for delimitation of taxa of Rosa sericea complex were studied. In this research, three taxa of the complex R. sericea, R. omeiensis, and R. sikangensis have been studied. A total of 41 populations and...

Flowering plants always attract animals providing rewards or deceptive signals to gain reproductive success. However, there is no well-documented reporting about a pollination mechanism with both rewards and deceptive signals by a same object. We found Cypripedium wardii flowers seem to attract visitors by the white pseudopollenlike trichomes on la...
We studied hybrid interactions of Lilium meleagrinum, Lilium gongshanense, and Lilium saluenense using an integrative approach combining population genetics, fieldwork, and phenological research. These three species occur along an elevational gradient, with L. meleagrinum occurring at lower elevations, L. saluenense at higher elevations, and L. gon...
Following evidence from morphology and molecular phylogenies, we integrated Nomocharis Franchet (1889: 113) into Lilium Linnaeus (1753: 302) and made the combination L. farreri (W.E.Evans) Y.D.Gao in Gao & Gao (2016: 207) based on Nomocharis farreri (W.E.Evans 1925: 20) Harrow (1928: 76). Unfortunately, this combination in Lilium was blocked by L....
The name Lilium tenii H.Léveillé (1909: 263) was assigned by Hector Léveillé to a specimen collected by Father Siméon Ten on 15 August 1907 from Dongchuan (Tong-Tchouan) of Yunnan Province, China. The name L. tenii has long been treated as a synonym for Lilium primulinum var. ochraceum (Franch.) Stearn (1948: 13). The treatment was based on the mon...
The first chloroplast genome of the fern genus Polystichum Roth (Dryopteridaceae) is reported here. Polystichum deltodon (Baker) Diels belongs to subgenus Haplopolystichum (Polystichum; Dryopteridaceae), many species of which are endangered or critically endangered species. The complete chloroplast genome of P. deltodon was determined for the first...
Angelica sylvestris L. is the type species of the genus Angelica L., which was considered as one of the largest and most complicated groups in the family Apiaceae. The complete chloroplast genome of A. sylvestris was determined for the first time, and revealed a circle quadripartite structure of 146,910 bp in length comprising a large single-copy r...
Taxonomic revision of a single species complex of Photinia integrifolia (Rosaceae) is accomplished during the revision of the genus Photinia sensu stricto. The study is based on the protologues and type specimens deposited in relevant herbaria. Thirty-two names are recorded for a single species. Five names are proposed as new synonyms, six lectotyp...
Discerning species boundaries among closely related taxa is fundamental to studying evolution and biodiversity. However, species boundaries can be difficult to access in plants because ongoing divergence and speciation may leave an evolutionary footprint similar to introgression, which occurs frequently among species and genera. In this study, we s...
Based on different taxonomic treatments, there are different kinds of names. Accepted name, autonym, synonym, homonym, basionym, unresolved name, conserved name, rejected name, legitimate name, illegitimate name etc. are commonly used in plant Science. Unresolved names are those dubious names which are neither accepted nor synonym. Currently, the o...
East Asia harbors the highest level of floristic diversity among the world’s temperate regions. Despite the increase in phylogeographic studies of temperate plants in East Asia, far less attention has been paid to widely distributed deciduous shrubs that widespread across several floral regions. We sequenced two chloroplast DNA (cpDNA) fragments (n...
Explaining how plants from eastern Asia migrated to other Northern Hemisphere regions is still challenging. The genus Sorbus sensu stricto (including c. 88 species) is considered as a good example to illuminate this scenario, due to the wide distribution in the temperate zone and high diversity in the Himalayas and Hengduan Mountains. Based on four...
We discuss the typification of the name Lilium lancifolium (Liliaceae). We designate a specimen from UPS as the lectotype.
Youngia purpimea, a new species from southern Sichuan, China, is described and illustrated. This species is morphologically most similar to Y. szechuanica and Y. zhenyiana by having capitula with five yellow florets, but differs from the latter two by having leathery and undivided caudical leaves being glabrous on both surfaces and purplish red aba...
Continuous variation among Lilium stewartianum I.B.Balfour & W.W.Smith (1922: 127) and its close allies, L. habaense (1986: 51) and L. xanthellum F.T.Wang et Tang (1980: 283) have been observed by the author. In particular, L. habaense is distinguished from L. stewartianum on the basis of stamen having slightly shorter filaments (Wang et al. 1986)....
Several previous studies have shown that some morphologically distinctive, small genera of vascular plants that are endemic to the Qinghai-Tibetan Plateau and adjacent Hengduan Mountains appear to have unexpected and complex phylogenetic relationships with their putative sisters, which are typically more widespread and more species rich. In particu...
While most temperate plants probably underwent glacial constriction to refugia and interglacial expansion, another type of interglacial refugia might have existed to maintain alpine plants during warm periods. To test this hypothesis, we applied phylogeographic methods to 763 individuals (62 populations) which belong to 7 taxonomically difficult sp...
In order to clarify the interspecific relationships of a lineage in Pleurospermum, P. hookeri, P. yunnanense and P. giraldii, and to understand intraspecific divergence of P. hookeri, a phylogeographic study was conducted based on 198 individuals from 24 populations. Three cpDNA regions, ndhF-rpl32, trnL-trnF and trnQ-rps16, were sequenced in the p...
In this revision, we treat Lilium wenshanense L.J. Peng & F.X. Li, L. jinfushanense L.J. Peng & B.N. Wang and L. huidongense J.M. Xu from China as synonyms of L. brownii F.E. Brown ex Miellez, L. taliense Franchet and L. lijiangense L.J. Peng, respectively. We justify the synonymy by demonstrating the existence of continuous morphological variation...
In this revision, we treat Lilium wenshanense L. J. Peng & F. X. Li, L. jinfushanense L. J. Peng & B. N. Wang and L. huidongense J. M. Xu from China as synonyms of L. brownii F. E. Brown ex Miellez, L. taliense Franchet and L. lijiangense L. J. Peng, respectively. We justify the synonymy by demonstrating the existence of continuous morphological va...
Past climates experienced by fossil plant species have often been inferred based on the environmental requirements of their evolutionarily nearest living relatives (NLR). Here we have combined paleoclimatic estimation using NLRs with ecolological niche modeling (ENM) and have demonstrated the combined approach by inferring the Eocene environment of...
We describe and illustrate Lilium yapingense sp. nova (Liliaceae) and show its position within the Lilium—Nomocharis complex (Liliaceae). It is similar in appearance to L. nanum but differs by (1) having no spots on the tepal bases, instead possessing symmetric stripes; (2) nectaries lacking fimbriate projections on the surfaces, but having two dar...
Fifty-two populations representing thirty-two taxa of Lilium L. from China are karyologically analyzed. The results showed that all populations have the same basic chromosome number x012, and all species are diploid except Lilium tigrinum, which is triploid with 2n036. In addition, one population of L. sulphureum is aneuploid with 2n023. The karyot...
