Nomenclatural notes.

Jasminum laxiflorum was described ( Gagnepain 1933a, b) based on seven gatherings ( E. Poilane 19787, F. Evrard 2618, coll. Khai 161, C. Thorel 862, L. Pierre 327, A. Chevalier 29979, and Godefroy s.n) collected from South Vietnam. None of them was designated as a holotype. We found nine specimens matching the original description and information given on the labels which are included in the protologue, and several duplicates. A survey of the literature ( Ho 2000; Tran 2003) and multiple herbaria revealed that a lectotype for J. laxiflorum has not yet been designated. Therefore, L. Pierre 327, the specimen P03868745 at P, which best represents the species, is designated here as a lectotype following Arts. 9.3 and 9.11 of ICN ( Turland et al. 2018). Other specimens at A, P, and BM (A: A00105308, A00105309, A00105310, A00105313; BM: BM000997658; P: P03868746, P03868747, P03868750) are designated here as isolectotypes.
