i8io The Trees of Great Britain and Ireland 



Ridgway, in Proc. U.S. Museum, 86 (1882), speaking of P. angulata, states that 

 it is a very common tree on rich bottom lands and along alluvial banks of streams, 

 where it occasionally attains immense size. Trunks of 5 to 6 ft. diameter are not 

 uncommon, while trunks of 7 to 8 ft. are sometimes found, the stem being usually 

 more than 50 feet clear. The largest measurements were as follows :—

Timber 



The timber varies very much in quality, a variety known as yellow cotton- 

 wood being much the best. Mason says that he has known strong and good 

 houses built from it whose joists and sheathing boards were straight and sound 

 thirty years after they were put up. But the timber of some trees is soft, spongy, 

 and worthless. Sargent says that the wood is very difficult to season, and is 

 apt to warp badly in drying, but of late years has been used in the Mississippi 

 valley for packing-cases and other coarse work. (H. J. E.)

A tree, attaining over 100 ft. in height and 15 ft. in girth. Bark deeply and 

 regularly furrowed on old stems. Young branchlets angled, glabrous, greenish 

 with white lenticels ; on vigorous shoots, with projecting ribs, persistent two or three 

 years. Buds greenish, glabrous, only slightly viscid. Leaves (Plate 409, Fig. 15) 

 always longer than broad, averaging, when well-developed, 7 in. long and 5 in. 

 wide, triangular-ovate ; base broad, truncate, subcordate or deeply and narrowly 

 cordate ; apex acute or shortly acuminate ; glabrous and firm in texture when 



1 p. carolinensis, MoencB, Bdume Weissenstein, 8i (1785), is said by Willdenow, Sp. PI. iv. 80S (1805) and by Haitig, 

 Naturges. Font. Culturpfl, 436 (1851) to be identical with P. monilifera, Aiton; but this is uncertain, and Moench's plant 

 may have been the female tree of P. angulata.
