the Khasia hills and Malaya, as Sir Joseph Hooker pointed out

in his Introductory Essay to the Flora Indica (p. ), and as 
regards climate, humidity, etc., these regions are remarkably 
of closely representative species of Strychnos in S.W. India, the 
Khasia Hills and Malaya is not surprising, although as a rule 
the range of the several species appears to be restricted. 
The Khasia Hills have in addition two endemic species, 
S. axillaris, Colebr., belonging to the section Penicillatae, of 
which several other species are recorded from Indo-China, 
Malaya, ete., and S. Wallichiana, Benth., a very distinct species, 
which occurs in Silhet, Chittagong and the Lushai hills, with 
a variety intermedia, in Chittagong and a second variety ovata, 
in Peou. 
The typically S. India and Ceylon species S. potatorum is 
also recorded from Prome and Peeu, but S. Nus-vomica does 
not occur, and is represented in Burma and Siam by S. Nua- 
blanda. 
The Malayan and Indo-Chinese region is rich in species 
of Strychnos. Ten belong to the section Penicillatae and, 
with the exception of S. pubescens which apparently extends 
to Borneo, they appear to be endemic and well defined. 
Of the three representative of the section Brevitubae, S. hypo- 
gyna from Tenasserim is nearly related to S. andamanensis, but 
S. Maingayi and S. hirsutiflora from Perak, are both very 
distinct and peculiar species. ; 
In the section Lanigerae, S. laurina from Tenasserim 
a
