254 LT.-COL, D. PRAIN ON THE MANSONIEEX, 
few dayslater I sent him a sample of the dark brown kind, 
bought in Rangoon at R 3 per viss (about R 1 [one shilling and 
fourpence] per 1b.)." 
Mr. Manson's surmise has since been confirmed. In 
November 1904 he sent to the Caleutta Herbarium specimens 
ot * two species of trees, each of which is called by the Burmese 
Kalamet." One of the two is the species already represented 
by the leafspecimens of March 1901 and the fruiting speci- 
mens of August 1902. The other is a tree with larger and 
differently shaped leaves, hitherto unrepresented in the Caleutta 
Herbarium, as to which, in the absence of flowers and fruit, all 
that ean be said is that it differs from the first certainly specifi- 
cally and possibly generically. In subsequent references the 
Kalamet from the Mawdoung Range, of which we have known 
the fruits since 1903 and of which we now know the flowers, 
will be spoken of as Kalamet A, the second one being referred 
toas Kalamet B. 
The history of this enquiry illustrates the necessity for caution 
in relying on the incidence of the vernacular names of economie 
products. Besides avoiding the confusion, pointed out by 
Sir D. Brandis, whieh has taken place between Kalamet as a 
whole and Toungkalamet, it 1s necessary to distinguish between 
two Kalamets of Burmese origin, both as economie products 
and as botanical species. It is further clear that in Burmese 
marts the name Kalamet may be applied to a product of 
Malayan origin. We are not yet able to say whether the 
commercial distinction between “dark brown" and “ golden 
brown" Kalamet corresponds wholly or in part with the 
botanical difference between Kalamet A and Kalamet B. We 
do not know the Malay name of the wood from the Straits 
Settlements which is sold in Burma as Kalamet, nor have we as 
yet any means of judging whether this Malayan Kalamet is the 
product of either of the Burmese species. These points can only 
be settled by local investigation both in Burma and in Malaya. 
If, however, we are still unaware of the source of the Malay 
Kalamet, and are unable to say more of the Burmese Kalamet B 
than that it is quite different from the other Burmese Kalamet, 
the recent communication to the Calcutta Herbarium of flowering 
specimens fortunately enables us to deal finally with Kalamet A. 
These specimens have been examined at Calcutta by Mr. J. R. 
Drummond, who has lately been at work in the Herbarium there ;
