126 CONIFEROUS TREES 



leaves are thin, i^ inches long, and the cones re- 

 markably neat, being ij inches long by i inch 

 diameter. For confined spaces or rock-work this 

 variety is to be recommended, the height rarely 

 exceeding 4 feet. 



P. CEMBROIDES, Zuccavifii. (Synonyms : P. 

 Llaveana, Schlectendal ; P. osteosperma, Engel- 

 mann.) Arizona. 1839. — This is of no great 

 value for the purpose of ornament, and less so for 

 timber. As generally seen, it is of contorted and 

 dwarfed appearance, with irregularly arranged 

 branches, well furnished with nearly erect-growing, 

 stifiish leaves, each fully ij inches long and bright 

 green. The cones are small, neat, and dull brown, 

 each about i| inches long. 



P. CLAUSA, Vasey. (Synonym : P. inops clausa, 

 Engelmann.) Florida. — This bears a great re- 

 semblance to the better-known P. inops, which 

 in this country forms a low bushy tree of 16 feet, 

 or thereabout, in height, the branch-spread being 

 nearly as much. The leaves of P. clmtsa are short 

 and glaucous, arranged in twos, while the plenti- 

 fully produced prickly cones are persistent on 

 the stem and branches for many years ; indeed so 

 persistent are they that I have frequently seen 

 them partially embedded in the wood of the 

 branches on which they were growing. It grows 

 in sandy barrens, and would no doubt be worthy 

 of trial for planting in similar places in this country. 



P. CONTORTA, Loudon. (Synonyms : P. Bour- 

 sieri, Carriere ; P. Bolanderi, Parlatore.) North- 

 West America, Alaska to California along the 

 coast. 1 83 1. — Amongst medium-sized pines, and 

 for planting where ground-space is at all cramped.
