FROM THE SOCIETY'S GARDEN. 237 



Leaves in threes, from an inch to an inch and a half in length 

 (on the wild specimens), rather rigid, slightly twisted at the 

 base, triquetrous, very dense, and of a light-green colour. 

 Sheaths short, and soon falling off or curling up. Seed-leaves 

 on the young plants from ten to twelve in number when they 

 first come up. Branches vertical, mostly in fives, but sometimes 

 more numerous in the whorl, rather slender, slightly incurved 

 and spreading, with tolerably smooth bark and remarkably small 

 buds, which are imbricated and non-resinous, or nearly so. 

 Cones single and sessile, from 2i to 3 inches in length and 

 If inch broad at the base, with six or seven rows of scales, and 

 tapering but slightly to a blunt point ; the scales are rounded 

 at the margins, | inch broad, slightly elevated and nearly all 

 of a size, except those close to the base, which are very much 

 smaller and rather hooked. Each scale contains within it two 

 wingless seeds, which are top shaped, slightly angled at the 

 smaller end, and about \ an inch in length. 



This Pine much resembles Pinus Llaveana in foliage and 

 general appearance, but it differs in having smaller leaves and 

 cones three or four times the size. 



Mr. Loudon in his last edition of the ' Arboretum Britan- 

 nicum,' p. 993, identifies this Pine with Pinus Llaveana of 

 Schiede ; but Pinus Llaveana has no resemblance whatever with 

 Pinus Cembra, either in habit, foliage, or cones. The cones of 

 Pinus Llaveana have but three rows of scales, while those of 

 Pinus Cembra have eight, and those of Pinus Cembroides six or 

 seven scales each ; the two latter however much resemble each 

 other in their cones (whence the name Cembroides), and chiefly 

 diffier in Pinus Cembra or the Siberian Stone Pine, having cones 

 rather larger than those of Pinus Cembroides, with five leaves 

 instead of three. 



Judging from locality and appearance, this Pine is likely to 

 prove hardy in England, and is quite new to the collections of 

 this country.

43. Pinus ORizABiE.* 



Received along with Pinus cembroides from Mr. Hartweg, 



who collected it on the mountain of Orizaba, where it 



forms a tree of moderate size. 



Leaves in fives, from 8 to 9 inches in length (on the wild 



specimens), very slender, sharp pointed, triquetrous, thickly set
