Canscora ciathula is not Canscora but rather belongs to the genus Phyllocyclus
Abstract
Canscora ciathula (gentianaceae) was described by Averyanov from Laos. examination of the type specimens revealed that it is conspecific with Phyllocyclus petelotii (Merrill) thiv and reduced here to synonymy.
Canscora diffusa var. tetraptera Naik & Pokle is reinstated and elevated to the rank of species. A detailed description, key to the species of Canscora in Peninsular India and photographs are provided to ease identification.
An account of the genus Phyllocyclus (Gentianaceae) for Thailand is presented. Three species are recognized, including two recently reported species, Phyllocyclus petelotii and P. parishii. A key to the Thai species, descriptions, illustrations, and conservation status are provided.
Abstract
The genus Canscora in South India is revised based on field and herbarium studies and in consultation with types and
protologues. C. pauciflora, which was previously treated as conspecific to C. diffusa is reinstated while C. sanjappae and
C. devendrae are synonymised under C. diffusa and C. stricta (= Canscorinella stricta) respectively. The present study
supports the exclusion of two species of Canscora i.e., C. stricta and C. bhatiana resulting in the establishment of the
new genus Canscorinella and two new combinations: Canscorinella stricta and Canscorinella bhatiana. The new genus
Canscorinella is characterized by the presence of actinomorphic corolla and isomorphic stamens. This brings the number
of species currently recognized for the genus Canscora to eleven worldwide, six (55 %) of which occurring in South
India. Descriptions, photo plates and keys to the South Indian species of Canscora and Canscorinella are provided here.
Key words: Canscora, Canscorinella, new genus, actinomorphic corolla, isomorphic stamens
A taxonomic revision of all genera belonging to Gentianaceae–Canscorinae, i.e., Canscora, Cracosna, Duplipetala, Hoppea, Microrphium, Phyllocyclus and Schinziella is presented, including keys to the taxa, distribution maps and seed coat descriptions. One new genus,
one new species and seven new combinations are described. In total seven genera and 23 species are recognized. All taxa are of palaeotropical distribution with centres in india and SE Asia.
The inventory of plant diversity, flora and vegetation in northeastern part of Hin Nam No National Protected Area (HNN NPA) is based on studies of 13 locations, both in sandstone (Phou Chuang Mountain) and in rocky karstic limestone at elevations 180–1492 m a.s.l. Six kinds of primary plant communities were recognized and described. They are: lowland semideciduous broad-leaved forests on flatland with alluvial soils (200–400 m), gallery evergreen broad-leaved forests on alluvial soils (180–220), lowland and submontane semideciduous and evergreen broad-leaved forests on sandstone (400–1200 m), montane evergreen broad-leaved, mixed and coniferous forests on sandstone (1200–1400 m), lowland semideciduous and evergreen broad-leaved limestone forests (250–500) and dwarf wind formed semideciduous broad-leaved limestone scrub on tops of limestone hills (400–600 m). The monograph includes – brief characteristic of physical geography, climate and geomorphology of studied area; description of all studied primary kinds of vegetation; schematic vegetation map of the studied area; brief characteristic of the regional flora and its comparison with local flora of allied Phong Nha – Ke Bang National Park (Vietnam); identified lists of “key species”; analysis of threat and recommendations for management of the plant diversity. The set of appendices includes – the annotated illustrated list of collected and documented plant species (1); the list of all species reported for the area (2), the annotated illustrated list of illustrations (3) and illustrations. Assessment data are documented by 1100 herbarium specimens with 670 collecting numbers belonging to 123 families, 340 genera and 545 species. Being combined with previously available data studied local flora includes 175 families, 755 genera and 1519 species of vascular plants. At least 30 families, 141 genera and 332 species were recorded for HNN NPA at first. Five families, 37 genera and 172 species were recorded as a new for the flora of Laos. Twenty species and one variety are discovered and described a new for science. They are Amomum odoratum, Aspidistra medusa, Begonia tatianae, Campylotropis microphylla, Canscora ciathula, Chiloschista pulchella, Cleisostoma verrucosum, Eriobotrya capitata, Eriobotrya integrifolia, Euonymus splendens, Hoya aphylla, Lysimachia trifida, Melicope petrophila, Munronia lancifolia, Oberonia vesiculifera, Oreocnide laotica, Oxyspora decidua, Paphiopedilum appletonianum var. leopardinum, Paulownia laotica, Peliosanthes cryptogamica and Sonerila hirsutissima. The studied region is identified as particularly rich both in endemic and in widespread plants. The high diversity of vegetation and habitats effectively support high level of natural plant diversity of aboriginal flora, which can contain at least 2500–3000 native species. The book contains 431 p., 15 tables and 1397 figures.
A new species, Canscora shrirangiana Kambale, Kolte & A. Deshp. is described and illustrated here. The new species is morphologically similar to C. pauciflora.
