Abstract

Based on detailed morphological comparisons and literature examinations, it was found that the two species, Glochidion acuminatum Müll. Arg. and G. triandrum (Blanco) C. B. Rob. (Phyllanthaceae), can be readily distinguished from one other and warrant acceptance as separate species. Here, their morphological circumscription and geographical distribution are reevaluated. In addition, the three names, viz. G. acuminatum, G. eleutherostylum Müll. Arg. and G. quinquestylum Elmer, are lectotyped and the name G. triandrum is neotyped.

... The species is represented in Taiwan by the typical variety, and another variety is distributed in Thailand and Yunnan province of China (Li and Gilbert 2008;Yao and Zhang 2015b). A detailed morphological comparison between the two taxa can be referenced in Yao and Zhang (2015b). The typical variety can be distinguished from all other Taiwanese Glochidion species by its small (5-7 mm in diameter) and deeply 6-or 8-grooved capsules ( Figure 2C). ...

A comprehensive taxonomic revision of the genus Glochidion J.R. Forst. & G. Forst. from Taiwan in China was carried out based on the examination of herbarium specimens and filed investigations. Eight species and three varieties are recognized, including a new species endemic to Taiwan, G. lanyuense Gang Yao & S.X. Luo, which is described and illustrated. Three names, viz. G. chademenosocarpum Hayata, G. kusukusense Hayata, and G. ovalifolium F.Y. Lu & Y.S. Hsu, are reduced to the new synonyms of G. rubrum Blume, G. lanceolatum Hayata, and G. ellipticum Wight, respectively. Two names, viz. G. lanceolatum Hayata and G. suishaense Hayata, are lectotypified here. A key to the Glochidion species in Taiwan is provided.

Based on field observation and extensive herbarium studies, a comprehensive taxonomic revision of the genus Pogostemon in China was carried out. Twenty-seven species and two varieties are recognized, among of which eleven species and one variety are endemic to China. A new species, P. henanensis, is described and illustrated. Two new combinations, P. glaber var. tsingpingensis and P. latifolius, are proposed. Six names are reduced to synonymy, eleven names are lectotypified and a name is neotypified. The record of P. menthoides in China is corrected as P. fraternus. One species, P. pressii, is listed as dubious species in China. In addition, nomenclature, descriptions and distribution maps of each species and variety as well as a key to Chinese Pogostemon taxa are presented.

Based on morphological and palynological comparisons, three names, viz., Glochidion mishmiense Hook. f., G. pseudo-obscurum Pamp., and G. rubidulum Chin are reinstated. The three names have previously been reduced to synonymy of G. zeylanicum var. tomentosum (Dalzell) Trimen, G. puberum (L.) Hutch., and G. thomsonii (Muell. Arg.) Hook. f., respectively. Floral morphological characters of G. mishmiense are described here for the first time. In addition, G. mishmiense and G. pseudo-obscurum are lectotypified, and G. mishmiense is newly recorded in China, while the record of G. thomsonii in China is rejected.

Phylogenetic relationships within tribe Phyllantheae, the largest tribe of the family Phyllanthaceae, were examined with special emphasis on the large genus Phyllanthus. Nuclear ribosomal ITS and plastid matK DNA sequence data for 95 species of tribe Phyllantheae, including representatives of all subgenera of Phyllanthus (except Cyclanthera) and several hitherto unplaced infrageneric groups, were analyzed. Results for ITS and matK are generally concordant, although some species are placed differently in the plastid and ITS trees, indicating that hybridization/paralogy is involved. Results confirm paraphyly of Phyllanthus in its traditional circumscription with embedded Breynia, Glochidion, Reverchonia, and Sauropus. We favor the inclusion of the embedded taxa in Phyllanthus over further generic segregation. Monophyletic Phyllanthus comprises an estimated 1269 species, making it one of the "giant" genera. Phyllanthus maderaspatensis is sister to all other species of Phyllanthus, and the genus appears to be of paleotropical origin. Subgenera Isocladus, Kirganelia, and Phyllanthus are polyphyletic, whereas other subgenera appear to be monophyletic. Monotypic Reverchonia is sister to P. abnormis, arborescent section Emblica to herbaceous Urinaria, free-floating aquatic P. fluitans to the weed P. caroliniensis, and the phyllocladous section Choretropsis to the delicate leafy P. claussenii. The unique branching architecture known as "phyllanthoid branching" found in most Phyllanthus taxa has been lost (and/or has been derived) repeatedly. Taxonomic divisions within Phyllantheae based on similar pollen morphology are confirmed, and related taxa share similar distributions. We recommend recognition of six clades at generic level: Flueggea s.l. (including Richeriella), Lingelsheimia, Margaritaria, Phyllanthus s.l. (including Breynia, Glochidion, Reverchonia, and Sauropus), P. diandrus, and Savia section Heterosavia.

This revised synopsis of the taxa of Euphorbiaceae recognizes, and provides keys to, 5 subfamilies, 49 tribes, and 317 genera. Two new tribes, Croizatieae and Podocalyceae, are proposed, as well as four new subtribes, Leptopinae, Podocalycinae, Pycnocominae, and Tetracoccinae; five taxa are reduced to subtribal status. One genus (Ophellantha) is reduced to a section; 14 new binomial combinations are proposed. Lectotypifications are provided for almost all taxa not previously typified.

A synopsis of the Euphorbiaceae of Sumatra is offered, following a pattern set in previous accounts, particularly that in The Euphorbiaceae of Borneo, to which reference is made wherever possible-a full list of synonyms and literature is given only for those taxa not occurring in Borneo. New taxa are listed on p. 374. An unexpected late loan of Sumatran material from Leiden contained many taxa not treated below; these are listed in an un-indexed addendum on p. 374 and attention is drawn to them by * printed beside each pertinent genus entry. The loan also provide one extra genus, Dalechampia.

Evidence suggests that of the widely distributed sets of E. D. Merrill's "illustrative specimens" for F. M. Blanco's names of Philippine plants, the first, most complete, and best labelled extant set is the one at the U.S. National Herbarium. Workers considering neotypification of Blanco's plant names should give special consideration to the materials at US.
