GENIUS PINUS. 83 



P. cla,usa,| Vasey. {Synonym : — P. inops clausa, Engel- 

 mann.) Florida. — This bears a great resemblance to the 

 better known P. inops, which in this country forms a low 

 bushy tree of i6 feet, or thereabout, in height, the branch 

 spread being nearly as much. The leaves of the present 

 species are short and glaucous, arranged in twos, while the 

 plentifully 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 t*he 

 wood of the branches on which they are growing. It grows 

 in sandy barrens, and would no doubt be worthy of trial for 

 planting in similar places in this country. 



P. COntorta, Douglas. {Synonyms : — P. Boursieri, 

 Carriere ; P. Bolanderii, Parlatore.) North-West America, 

 Alaska to California along the coast. 1831. — Amongst 

 medium-sized pines, and for planting where ground space is 

 at all cramped, this species is valuable. The habit is irregu- 

 larly conical, the lower branches having no decided mode of 

 growth, but being short and spreading in almost every direc- 

 tion. In general appearance and foliage the tree bears some 

 resemblance to P. insignis, but is of duller foliage-tint, the 

 leaves arranged in twos, and thickly on the branches. Cones 

 are produced freely, they being ovoid-conical, 2^ inches long, 

 and greyish-brown in colour The scales are formidable, the 

 umbo being prolonged into a long, awl-shaped point. The tree 

 varies a good deal in this country, and I have seen specimens 

 which, from their depth of foliage colouring and neat narrow 

 pyramidal habit, were highly prized by their owner. Planted 

 in rough, stony, or rocky ground, it seems most at home, and 

 under which conditions I have known the annual rate of 

 growth to be 2 feet for several consecutive years. 



P. Coulteri, Don. {Syno7iyms : — P. macrocarpa, Lind- 

 ley ; P. Sabiniana Coulteri, Loudon.) California. — This can 

 hardly be classed as even a second-rate ornamental conifer 

 in Britain, the shabby, meagre, tufted appearance of the 

 foliage and the betrayal of bare branches being out of 

 keeping with our ideas of a beautiful tree. Generally such is
