Abstract: Disporum nanchuanense (Colchicaceae), a new species from Jinfo Mountain National Nature Reserve, Nanchuan District, Chongqing, China, is described and illustrated. It is similar to D. longistylum and D. megalanthum, but differs from the former in its stem branched type, tepals colour and size, stamens and pistil size; and it differs from the latter in inflorescence position, tepals shape, stamens position, pistil position and size. Meanwhile, the new taxon is assessed as Vulnerable (VU D2), according to the IUCN Red List criteria. Furthermore, an identification key to all Chinese species of Disporum is provided.

Taxonomic revision of Disporum Salisb. (Colchicaceae, Uvularioideae) of Taiwan https://phytokeys.pensoft.net/article/33516/ PhytoKeys 119: 1-22

DOI: 10.3897/phytokeys.119.33516

Authors: Chao Chien-Ti, Tseng Yen-Hsueh

Abstract: A taxonomic revision of Disporum of Taiwan is presented with two species and one variety being recognised. The diagnostic characters of Disporum include the colour of tepals, stolon morphology, the trichomes of filaments and style and leaf morphology. These characters, along with karyotype and pollen morphology, are discussed and evaluated amongst different taxa. As a result, D. kawakamii and D. shimadae are treated as independent species, rather than varieties of D. cantoniense and D. sessile, respectively. Disporum nantouense is treated as a synonym of D. sessile var. intermedium stat. nov. Detailed descriptions, type information, diagnostic key, line drawings, photos and distribution maps are provided.
