 large tree. Himalayas. Introduced 

 in 1807, and requiring protection 

 in England. 



P. longifolia is a native of Nepal, 

 on the mountains ; and also of the 

 lower and warmer parts of India, 

 where the tree is cultivated on ac- 

 count of its beautiful foliage and 

 graceful habit of growth, but where it 

 never attains the same magnitude as 

 on the Himalayan Mountains. It was 

 introduced into Britain in 1801, and for a long time was treated as a green- 

 house plant ; it is now 

 found to stand the open 

 air, but not without 

 protection during win- 

 ter. The largest tree 

 in England is believed 

 to be that at Drop- 

 more, It was, in 1837, 

 nearly 12ft. high ; but 

 it is covered every win- 

 ter with a portable roof 

 of fern, enclosed in 

 mats, and supported by 

 a wooden frame ; the 

 sides being closed in 

 with the same mate- 

 rials, but with two 

 doors opposite each 

 other, to open on fine 

 days, to promote ven- 

 tilation. Mr. Lawson 

 suggests that the ten- 

 derness which is appa- 

 rent in some individuals 

 of this species may 

 possibly arise from the 

 seed from which they 

 were I'aised having been 

 produced by trees grow- 

 ing in the warm valleys 

 of Nepal ; and that, 

 " by procuring seed i 

 from trees at the hiah- 

 est elevation at which 

 they are found to exist, \ ; 

 plants might be raised >^' 

 sufficiently hardy to 

 stand the climate of 



Britain." isos. p. longifolia.
