CHINA. Yunnan: Mengtsze, alt. 1700.m., A. Henry (No. 9340, type; 
climber, flowers white; No. 9340*; with fruits); same locality, alt. 1500 m., A. 
Henry (No. 9340^; hairy form with younger inflorescences). 
^ — At first sight this species resembles P. racemosa Roxburgh, but the structure of 
the flowers is very different. It is somewhat intermediate between the sub- 
genera Euporana and Dinetus, and I think it best to refer it to a separate sub- 
genus, Pseudodinetus. The stamens are of unequal length but are inserted in one 
row; the stigma seems to be different from those of Euporana and of Dinetus, being 
globular as in the first but also slightly emarginate as in the last subgenus. The 
inflorescence of the type is glabrous or nearly so, except the small bracts, while 
in No. 9340* the peduncles, petioles and sepals are more or less hirsute at least 
when young. 
Subgenus 3. DINETUS Peter in Engler & Prantl, Nat. Pflanzenfam. IV. Abt. 
. 9 a, 25 (1891), exclud. P. paniculata, Roxburgh. 
To this subgenus, the type of which is Porana racemosa Roxburgh, Irefer all the 
species with the exception of P. dinetoides, the ovaries of which contain only two 
ovules. They have a more distinct narrower tube, and the stamens have very short 
filaments, According to the size of the flowers there are two distinct groups in t 
subgenus, the first representing Dinetus proper, the flowers of which are small and 
all the sepals are equally enlarged on the fruit; and the second with larger flowers 
and the sepals unequally enlarged on the fruit. (See also the key, p. 358.) 
7. Porana malabarica Clarke in Hooker f., Fl. Brit. Ind. IV. 223 (1883). 
Mim ics Dalzell & Gibson, Bombay Fl. 162 (non Roxburgh, fide Clarke) 
1). 
INDIA. Malabar and Concan: without precise locality; Stocks & Law 
Porana, No. 3, Herb. Ind. Or.). i 
This species is closely related to P. racemosa Roxburgh, differing from it ap- 
parently only in the larger size of the sepals on the fruit. :
