Abstract
A new species, Ophiorrhiza monsvictoriae S.S.Zhou & L.D.Duan, discovered at Natma Taung (Mt.Victoria) National Park, Chin State, Myanmar, is described and illustrated. The new species is morphologically similar to O. dulongensis, but differs from the latter by its stipules broadly triangular, 2–4 mm long, inflorescence axillary, 1-flowered, bracts lanceolate to subulate, 1–2 mm long, puberulous, calyx pilose, 1–2 mm long, lobes and tube equal length, corolla narrowly funnelform, 15 mm long, puberulous outside.
Highlights
The genus Ophiorriza Linnaeus belongs to the tribe Ophiorrhizeae in the subfamily Rubioideae (Bremer and Manen 2000; Duan et al 2019)
A morphological description (Stearn 1983) of the new species was prepared from living plants and five dried herbarium specimens (HITBC: herbaria of Xishuangbanna Tropical Botanical Garden, the Chinese Academy of Science)
O. monsvictoriae principal veins raised on both sides of leaf blade; stipules broadly triangular, 2–4 mm long inflorescence axillary, 1-flowered; peduncle puberulous; bracts lanceolate to subulate, 1–2mm long, puberulous calyx pilose,1–2 mm long, lobes and tube equal in length; corolla narrowly funnelform, 15 mm long, puberulous outside
Summary
The genus Ophiorriza Linnaeus belongs to the tribe Ophiorrhizeae in the subfamily Rubioideae (Bremer and Manen 2000; Duan et al 2019). A morphological description (Stearn 1983) of the new species was prepared from living plants and five dried herbarium specimens (HITBC: herbaria of Xishuangbanna Tropical Botanical Garden, the Chinese Academy of Science). Herbarium and fresh specimens of Ophiorrhiza dulongensis (KUN: herbaria of Kunming Institute of Botany, the Chinese Academy of Science) (Lo 1990) were examined.
