 Capparis yunnanensis Craib & W. W, Sm. Notes Bot. Gard. Edinb. 9: 91. 1916. 



Indo-China, TonÈ-in, Chapa, Pételot 5951, April 1936, a large liana along mountain 

 streams, ait. 1200 m. Yunnan.

 in its shorter inflorescences. I am now convinced that the Chapa material 

 should be referred to this Yunnan form.
