VITACEAE 
Tetrastigma Henryi Gagnep. Not. Syst. 1: 264. 1910. Fer. p AG. 23 ‘JPo.1/94.2 
INpo-Cæaina, Tonkin, route from Hanoi to Hoa Binh at Muong Thon, Pételot 5975, 
March 1933, in savannas, alt. about 200 m. VYunnan, Haïinan. 
With Gagnepain’s interpretation of this species as having from palmately 
3-foliolate to pedately 5-foliolate leaves, it is difficult to see how Pételot 
3975 with strictly 5-foliolate pedate leaves can be distinguished. It may 
be that more than a single species was included in the original description, 
but in that case it is believed that the species should be interpreted from 
the first number cited, Henry 11756, a form with strictly 3-foliolate leaves. 
Henry 9992, the last number cited by Gagnepain, is very closely matched 
by Pételot 5816 from Chapa, both specimens being in fruit and in about 
the same stage of development; and yet one hesitates to state that Péfelot 
5975, with pedately 5-foliolate leaves, represents the same species as Pételot 
3816 with digitately 3-foliolate ones.

A species, in accordance with Gagnepain’s treatment of the genus, allied 
to Tetrastigma erubescens Planch. but with differently shaped very much 
larger leaflets.
