lines long. Leaves two from each sheath, equal, from 

 7 to 8 inches long, acute with a sharp point, convex on 

 the back, slightly scabrous with eight rows, in pairs, of 

 very minute thorns which produce a striated appearance, 

 hollow on the under surface, serrated, Cones ovate-coni- 

 cal, nearly four inches long. Scales rhomboid, unarmed. 



The flower is unknown. A single ripe cone that had 

 cast its seeds, and a branch, being all the materials 

 furnished for description. Specimens of the wood that 

 have been brought in contain more resinous matter 

 than any other species of coniferse I ever saw. It 

 appears like woody fibre immersed in resin. The Karens 

 make tar from the wood, by a very simple process; and 

 large quantities of both tar and pitch might be manufac- 

 tured in the forests, if a remunerative price could be 

 obtained for the article. 



The tree is not found west of the Donaw mountains, 

 a part of an unbroken granite range that runs down from 

 the falls of the Salwen to the old city of Tenasserim, and 

 which here separates the valley of the Thoungyeen from 

 the region watered by the Gyaing and its tributaries. 



This pine is not among the twenty four species described 

 by Loudon as the denizens of Great Britain, nor among the 

 twelve species described, and figured by Michaux in his 

 "North American Sylva"; yet it may after all, prove to 

 be a variety of P. longi/alia, which it more closely resem- 

 bles than any other species, but from which it differs, 

 among other things, in having only two leaves to each 

 sheath in the specimens I have examined, while that has 

 three. Previous to publishing the above communication, 

 a friend, Mr. Laidlay the Secretary of the Asiatic Society, 

 submitted it to Dr. Ai'Clelland, while he was in charge 

 of the Botanical Garden, and that gentleman, with 

 P. longifulia growing in the garden before him, gave it as 

 his opinion that the Tenasserim tree was a new species. 

 If I have erred, therefore, in regarding it as such, I have 

 done so with the highest official botanical authority in 

 India.
