Nomenclatural notes.

Jasminum rufohirtum was described ( Gagnepain (1933a, b) based on two gatherings ( Pételot 5032 and H. d’ Orléans s.n) collected by Pételot and H. d’ Orléans from north Vietnam and Laos respectively. While tracing the holotype, we found two duplicates matching the detailed description and specimen label information which are included in the protologue. A survey of literature and virtual herbaria revealed that a lectotype for J. rufohirtum has not been designated by the earlier workers ( Miao 1992; Chang et al. 1996; Ho 2000; Tran 2003; Prachaya et al. 2004). We selected the P specimen P00644294 as a lectotype following Arts. 9.3 and 9.11 of ICN ( Turland et al. 2018) as it represents the species best. The other specimens at P, and NY, are designated here as isolectotypes.

Grows in the forest at altitude 200-1000 m.a.s.l. Flowering in April - May, fruiting May - July.

Distribution.
