APOCYNACEAE. — TRACHELOSPERMUM 333 



1600 m., July 1907 (No. 2342^). Kweichou : "environs de Kouy- 

 yang, mont du College, rare, 25 avril 1898," J. Chaffaanjon; "environs 

 de Lo-Pie, avril 1898," J. Seguin; "environs de Tou-chan, 3 juin 

 1899," J. Cavalerie (ex L^veill^). 



On account of the glabrous mouth of the corolla and of the exserted anther- 

 tips I refer Wilson's plant as a variety to T. gracilipes Hooker f. So far as I can 

 judge by fragments kindly sent to me by Mgr. Leveille from one of his type 

 specimens the plant from Kweichou is the same as that from Hupeh. The sta- 

 mens are exserted and not included as stated by the author in his description. 

 I am not sure if all three specimens cited by Leveill6 really belong to our plant.
