33. Ionidium buxifolium Vent., Jard. Malmaison 1: sub tab. 27. 1803.

Ξ Afrohybanthus buxifolius (Vent.) Flicker

Lectotypus (designated here): M ADAGASCAR: sine loc., Commerson s.n. (P-JU n° 12784 [P00667193]!; isolecto-: G [G00341436]!).

Notes. – Flicker & Ballard (2015: 44) transferred Ionidium buxifolium to their new genus Afrohybanthus Flicker (Violaceae) . The authors cited the collection at P-JU as the holotype. Ventenat in Jardin de Malmaison (1803: sub tab. 27) explicitly mentioned “ex Herb Juss”. However, at G a very fragmented clastotype exists. We therefore considered that the collection in P-JU should be designated as the lectotype since it is a much better preserved collection and the specimen was used by Ventenat for the validation of the name Ionidium buxifolium .
