The Trees of Great Britain and Ireland

FRAXINUS CAROLINIANA, Swamp Ash

Fraxinus caroliniana, Miller, Dict, No. 6 (1768); Loudon, A7d. e¢ Frut. Brit. ii. 1237 (1838); Sargent, Silva N. Amer. vi. 55, tt. 274, 275 (1894), and Trees N. Amer. 762 (1905).
Fraxinus platycarpa, Michaux, Fl. Bor. Amer. ii. 256 (1803).
Fraxinus triptera, Nuttall, Gen. ii. 232 (1818).
Fraxinus cubensis, Grisebach, Cat. Pl. Cub. 170 (1866).

A tree attaining 40 feet in height, with a stem 3 feet in girth; bark marked by irregularly -shaped brown patches, separating on the surface into thin scales, Branchlets glabrous or pubescent, with white minute scattered lenticels. Leaflets (Plate 263, Fig. 12) seven, occasionally five, stalked (petiolule ¼ to ⅜ inch), about 3 inches long, oval; unequal, rounded, or broadly cuneate at the base; apex shortly acuminate ; finely and irregularly serrate; green and glabrous on the under surface except for some white pubescence along the sides of the midrib and nerves, or in some forms pubescent throughout. Leaf rachis, glabrous or pubescent, with two slight wings on the upper side, forming a groove.

Flowers (section Leptalix) diœcious in panicles arising in the axils of leaf-scars f the preceding year’s shoot; calyx present, persisting under the fruit ; corolla absent. Fruit broad, elliptic or spatulate; body short and compressed, surrounded by a pinnately-veined broad thin wing.

This species grows in river swamps in the coast regions of the Atlantic and Gulf States from southern Virginia to the valley of the Sabine river in Texas, extending through western Louisiana northwards to south-western Arkansas. It also occurs in Cuba.

This species was introduced into England in 1783, according to Loudon, who, however, mentions no trees of any size as growing in England in 1838. We have seen no specimens, except small trees at Kew, which are thriving. (A.H.)

FRAXINUS VELUTINA

Fraxinus velutina, Torrey, Emory’s Report 149 (1848); Sargent, Silva N. Amer. vi. 41, t. 267 (1894), and Trees N. Amer. 774 (1905).
Fraxinus pistaciæfolia, Torrey, Pacific R. Report, iv. 128 (1856).

A tree, 40 feet high, with a girth of stem of 2 feet. Bark deeply divided into broad flat broken scaly ridges. Shoots purple, covered with dense white pubescence ; lenticels white. Leaflets (Plate 265, Fig. 20), small, about 1½ inch long, three or five, occasionally seven or nine, or rarely only one, and variable in shape, margin, and insertion ; usually sessile, occasionally stalked, the terminal leaflet often obovate, the lateral leaflets commonly lanceolate with cuneate base and acuminate
