i6o2 The Trees of Great Britain and Ireland 



central Arkansas. It is usually a large shrub, growing on the borders of swamps 

 and in other wet situations. It is hardy in gardens as far north as Philadelphia. 



H. diptera is said by Loudon to have been introduced into England in 1758; 

 and a shrub trained against a wall produced flowers and fruit many years ago in 

 Loddiges' nursery. It appears to be extremely rare in cultivation at the present 

 time, the only specimen which I know being one at Kew, about 15 ft. high, obtained 

 from Meehan in 1896. This has not yet produced flowers or fruit. (A. H.)

 Carlomohria Carolina, Greene, in Erythea, i. 246 (1893). 



A tree, attaining occasionally in America 80 to 90 ft. in height and 9 ft. in girth, 

 but usually much smaller, and often a large bush throwing up several stems from 

 the ground. Bark divided into broad rounded scaly ridges. Young branchlets 

 stellate-pubescent. Leaves oval, 4 to 6 in. long, 2 to 3 in. wide, thicker in texture 

 than those of H. diptera, acuminate at the apex, rounded or cuneate at the base ; 

 margin minutely serrate, with very short callous points ; glabrescent above ; lower 

 surface pale or whitish, more or less densely covered with stellate pubescence; 

 petiole about \ in. long, covered with stellate hairs. 



Flowers, opening in spring just after the leaves begin to unfold, on long 

 slender pedicels, in fascicles of three or four ; calyx glabrous, four-ribbed, with four 

 minute deltoid ciliate teeth ; corolla bronzy red before opening, white when open, 

 with four short lobes, the division between the lobes not exceeding one-third the 

 length of the corolla; stamens, ten to sixteen, with glabrous filaments, connate 

 only at the base; ovary four-celled, glabrous; style glabrous. Fruit, ripening 

 late in autumn, and persisting on the tree in winter ; ellipsoid, 4 in. to 2 in. long, 

 with four broad wings; stone obovate, obscurely ridged; seeds rounded at the 

 narrow ends. 



This species as seen in cultivation is very variable ; and the following hybrids 

 or varieties are known : — 



I. Halesia stenocarpa, Koch, in Wochensckr. Gdrtn. u. Pflanzenk. i. 190 (1858), 

 and Dendrologie, ii. pt, i. 200 (1872). 



Leaves similar to the type in shape, consistence, and pale colour beneath • but 

 with more distinct serrations, and with sparser stellate pubescence on the lower 

 surface. Flowers : corolla deeply divided to near the base into four lobes • filaments 

 with scattered hairs, connate at the base or at some distance above it ; ovary and 

 style glabrous. Fruit with four narrow wings.
