224 The Gum Kino of the Tenasserim Provinces. [Aug. 



the writer, to be the production of the Pa-douk, the same tree as the 

 one in Maulmain thus denominated by the Burmans. Several years 

 before I had directed attention to this tree as producing an astringent 

 Gum resembling Gum Kino, but the Medical Officer to whom I sub- 

 mitted specimens of the Gum, said it was "a kind of Dragon's blood ;" 

 but after it was known that the Gum of the Pa-douk had been sold in 

 London for the veritable Gum Kino, another medical gentleman tried 

 in his practice the exudation of the tree in his compound in the place 

 of the Gum Kino in his stores, and reported the effects the same ; that 

 their medical virtues were alike. 



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 believed it was a species of Senna. The Rev. 

 H. Malcom, D. D. 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, " Pa-douk, or Mahogany, 

 (Sivietenia Mahogani) is plenty in the upper provinces, especially 

 round Ava, found occasionally in Pegu. In a native Pali Dictionary, 

 found in the Burmese monasteries, Pa-douk stands as the definition of 

 Pe-td-thd-ld, and the corresponding Sanscrit word in Wilson's Dic- 

 tionary, ijtfnu^T, is defined Pent apt era ; but the Pa-douk does not 

 belong to that genus. In Piddington's Index, however, Peetshala 

 stands as the Hindee name, and in Voigt's Catalogue, Peet-sal as 

 the Bengalee name of Pterocarpus marsupium ; and this brings us 

 nearer the truth, for Pa-douk is a name common to two different spe- 

 cies of Pierocarpus, 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. JVallichii, but 

 which was marked in Wallich's Catalogue, P. Dalbergioides, from 

 which differs in no well marked character excepting that the racemes 

 are axillary and simple, while in that they are terminal and " much 

 branched." Wight says, of P. Waliichii in his Prodromus, " stamens 

 all united or split down on the upper side only ;" so they are some- 

 times in our tree. In the figure that he gives in his Illustrations they 

 are represented as diadelphous, nine and one, and so they are seen 

 occasionally in our tree ; but the more common form is that of beine;
