PINUS 137 



P. Pinaster, Sol., var. minor, Loisleur (" Nouv. Duhamel," 



V. 242, 1812). 

 A plant under this name, without description, appears 

 in an old catalogue (1875) of R. Smith of Worcester. 



P. resinosa, Solander. 



The red pine of Eastern North America is akin to 

 P. laricio. So far no dwarf variations have been recorded 

 from the seed bed or the nursery, but in 1908 five dwarf 

 trees were found growing together in the woods in New 

 Hampshire and transplanted. Four of these are still 

 alive and all practically the same size. They are growing 

 in the grounds of Mr. George A. Carpenter, Wolfeboro', 

 New Hampshire, and of them Professor Sargent has 

 sent me specimen branches and photographs. They may 

 be thus described : 



P. resinosa, var. globosa, Rehder. 



Buds. — Conical; pale brown; under | inch; covered 

 with white resin. 



Branchlets. — Yellowish; glabrous; raised pulvini; short 

 and very crowded. 



Leaves. — In pairs, very densely crowded and forming 

 tufts; unequal in length — 4 to 6 J inches; flexible; semi- 

 terete; margins serrulate. Leaf-sheath persistent, | to 

 I inch. 



A strong-growing globular shrub; compact and densely 

 branched; measuring in 1921 5 J feet high by 8J feet in 

 diameter. 



P. Thunbergii, Pari. 



Syn. : P. Massoniana, Sieb. and Zucc. (not Lamb.). 



A Japanese pine, akin to P. laricio ; much used in Japan 

 for training into dwarf plants.

 native habitat reaches 100 feet. It is an interesting 

 species with dark bark ; short and stiff dark green leaves 

 borne in twos, and Hght grey winter buds.
