mon in all the islands, and if the writer is correct in considering the 
character of armed or unarmed trunk a trivial one, is the common 
Bonibax in S. Andaman, The leaves suit exactly, and though in S. 
Andaman the trunk of old tall trees is smooth, young saplings are 
armed, as are the ultimate branchlets even of old trees. The leaves are 
unlike any of the Indian or Burmese gatherings either of Bonibax 
malabaricum or of Bonibax insigne. 
2. A tree with unarmed trunk and branches, leaflets about 6, entire, 
obovate, acuminate 9-11 inches long, 2|-3 inches wide, gradually 
tapering into petiolules |-f inches long, stamens numerous. This was 
obtained only in Little Coco, it occurs in South Andaman also, for there 
are specimens at Calcutta, obtained by Mr. Kurz at Port Monat on the 
west coast. It does not at all resemble as to leaves of the other form nor 
does it resemble the leaves of Wallich’s type specimen of B. insigne. 
But its leaves precisely resemble those of Wall. Gat. 1840/4 (from Taong 
Doung, Burma), which was issued as B. malabaricum VAR. albiflorum, 
Wall. The number of stamens makes it impossible to refer the Anda¬ 
man plant at least to B. malabaricum. 
In South Andaman both forms have the leaves glaucous beneath ; in 
the Cocos neither form has ; so that this character perhaps cannot be held 
as valid. Mr. Kurz did not consider the two Andamans forms separable 
from each other, and in one place he referred them to B. malabaricum^ 
but afterwards, on account of the staminal character, united them to 
B. insigne. He has, however, left a manuscript name “B. heterophyllumfl 
which proves both that he had noted the existence of the two kinds of 
foliage and that he could not separate the plants exhibiting them from 
each other. 
It should be noted that the convicts and others at Port Blair dis¬ 
tinguish two kinds of “Semul” or “ Cotton-tree.” The distinction 
does not, however, apply to the two forms referred to above, but to these 
two taken together and to the following species.
