Based on examinations of specimens of Elatostema and Pellionia housed at K, KUN, L, P, PE, and YUNU, Elatostema section Weddelia series Salvinioida is taxonomically revised. Two species are recognized, described, and illustrated, and a key to the species is provided. Elatostema salvinioides var. robustum W.T.Wang is treated as a synonym of E. salvinioides W.T.Wang. Pellionia imbricata Gagnepain is transferred to Elatostema and a lectotype is designated herein. A new name, Elatostema simplicissimum Q. Lin, is provided because Elatostema imbricans was previously occupied. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 62–66.  相似文献

The new series Elatostema section Elatostema series Albopilosoides Q.Lin & L.D.Duan (Urticaceae) is described, and two new species of Elatostema, namely Elatostema albopilosoides Q.Lin & L.D.Duan and Elatostema purpureum Q.Lin & L.D.Duan. from south Guizhou province, south‐west China are described and illustrated. Both species were found growing only at the base of a large limestone chamber at an altitude of c. 800 m. Elatostema albopilosoides is morphologically similar to E. albopilosum W.T.Wang, but differs by having female inflorescences with peduncles 10–60 mm long (0–1.5 mm long in E. albopilosum) and receptacles 7–27 mm long, 7–24 mm wide (E. albopilosum: 1–4 mm long and 1–3 mm wide). Elatostema purpureum is also morphologically similar to E. albopilosum, but has stipules 5–6 mm long, 0.8–1.5 mm wide (4–7 mm long, 1.5–2.8 mm wide in E. albopilosum) and leaf blades obliquely elliptical to obliquely oblong‐obovate, 3.5–7.5 mm long and 1.5–2.5 mm wide (obliquely narrowly oblanceolate‐oblong, 12–17 cm long, 3–5 cm wide in E. purpureum:). © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 674–680.  相似文献
