74 The Pine tree of the Tenasserim Provinces. [Jan. 



pean who has visited the locality where the tree is indigenous, and from 

 specimens of the foliage and fruit, which he has brought away with 

 him, it appears to be a new species of Pimis that may be characterized 

 thus : — 



P. Latteri. Arbor 50 — 60 pedalis, cortice scabro, foliis geminis 7 — ■ 

 8 ; uncialibus caniculatis serratis* scabriosculo, strobilis and uncialibus 

 ovato — conicis, squamis rombeis inermis. 



Hab. In provincia Amherst : in convalli iluvii Thoungyeen. 



Descr. A tree of from 50 to 60 feet high, or more, and from 1^ to 

 2 feet or more in diameter. Sheaths of the leaves arranged spirally, 

 tubular, membranous, six 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-conical, nearly four inches long. Scales rhomboid, 

 unarmed. 



The flower is unknown. A single ripe cone that had cast its seeds, 

 and a small branch, being all the materials that have been furnished for 

 description. 



Specimens of the wood that have fallen under the writer's notice 

 contain more resinous matter than any other species of coniferse he 

 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 manufactured in the forests, if a re- 

 munerative price could be obtained for the article. 



This species has been named after Capt. Latter, as the discoverer, 

 because all our acquaintance with the tree has been derived from him, 

 beyond the vague knowledge that a tree of the pine family existed 

 somewhere on the banks of the Salwen. He reports it as growing 

 with the Engben, which is a species of Dipterocarpus that is met on 

 the sandy shores of the Province of Tavoy, side by side with Casurina 

 muricata. This Pine is not found west of the Donaw mountains, a 

 part of an unbroken range of granite mountains 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 



* Lindley says of the order, " Leaves — entire at the margins ;" but these are 

 certainly finely serrated ; and I find P. excelsa described with leaves " tooth-letted."
