Capparis mekongensis, Gagnep., var. crispata, Craib [Cappari- 
daceae-Cappareae]; varietas nova foliis angustioribus ag

Muang Sa, Nan, 180 m., dry mixed jungle, evergreen tree 
e. 9m. high, Kerr 2396. 
C. mekongensis is known to the writer from description only. 
Kerr’s plant which differs mainly in the points noted has had 
to be treated therefore in the meantime as a variety. A very 
similar plant was collected at Lampun (Winit 99), but the 
specimens forwarded consist of young flower-bearing twigs only. 
The collector further expresses a doubt as to whether the plant 
is deciduous or not.
