ON THE GUM KINO.

The next inquiry that arises is for the genus and species 
of the Pa-douk. When I first came to the coast, all the 
English residents of my acquaintance called it " Burman 
Senna/' and the surgeon of the station told me that he be- 
lieved it was a species of senna. The Rev. H. Malcom, 
D. D. 5 President of Georgetown College, Kentucky, who 
came out to India a dozen years ago in order to go back 
again and write a book, has stereotyped in his travels,— 
u Pa-douk, or Mahogany (Swieienia Mahogdni,) is plentiful 
in the upper provinces, especially round Ava, found occa- 
sionally in Pegu." In a native Pali dictionary, found in 
the Burmese monasteries, Pa-douk stands as the definition 
of Pe-ta-tha-la, and the corresponding Sanscrit word in 
Wilson's Dictionary is defined Pentaptera; but the Pa-douk 
does not belong to that genus. In Piddington's Index, 
however, Peetshala stands as the Hindu name, and in 
Voigt's Catalogue Peet-sal as the Bengalee name of Ptero* 
carpus marsupium ; and this brings us nearer the truth, for 
Pa-douk is a name common to two different species of 
PterocarpuSj but which look so much alike that they are 
usually regarded as one species. Undoubtedly one species 
is P. Indicus, and the other, I presume is the one named by 
Wight, P. Wallichii, but which was marked in Wallich's 
Catalogue P. Dalbergioides, from which it differs in no well 
marked character excepting that the racemes are axillary 
and simple, while in the latter they are terminal and "much- 
branched." Wight says of P. JVallichii, in his Prodromus, 
"stamens all united or split down on the upper side only," 
so they are sometimes in our tree. In the figure that he 
gives in his Illustrations they are represented as diadel- 
phous, nine and one, arid so they are seen occasionally in 
our tree; but the more common form is that of being split 
down the middle into two equal parts, of five each, as in 
P. Dalbergioides. The wood, too, resembles it. " Not un- 
like mahogany, but rather redder, heavier and coarser in 
the grain.' 5 It is often called " red wood" at Maulmain ;
