632 :5. Acer Fargesit, Rehder.’ Central China.
 * Leaves 3 to 4 inches long, ¾ to 1 inch broad, coriaceous, lanceolate, cuneate or rounded at the base, caudate or long acuminate at the apex, serrate on young plants, entire on old trees; nerves indistinct, about ten pairs, looping and not reaching the margin; green and glabrous on both sides, except for minute axil-tufts beneath, developed occasionally on leaves of old trees.
 * A small tree, introduced by Wilson in 1901; spring foliage and fruit bright crimson. Young plants at Coombe Wood are rather tender, and have only attained 1½ foot high in six years.


 * 6. Acer Davidi, Franchet.? Central China.
 * Leaves 3 to 4 inches long, 1½ inch broad, ovate, cordate at the base, long acuminate, slightly lobulate and crenately bi-serrate ; nerves prominent, about twelve pairs, looping before reaching the margin; upper surface dark-green, shining, glabrous ; lower surface pale, glabrous, except for reddish-brown axil-tufts.®
 * A tree, 50 feet in height, introduced by Maries in 1879. Young plants raised from seed sent by Wilson in 1902 are 10 to 12 feet high and perfectly hardy at Coombe Wood. Bark green, striped with white.
 * 6. Acer cratægifolium. See No. 10.
 * Leaves of this species, without lobes, are distinguishable from A. Davidi by the absence of the conspicuous axil-tufts on the lower surface.

II. Leaves simple, three-lobed.


 * 7. Acer monspessulanum, Linnæus. Southern Europe, North Africa, Asia Minor, Caucasus.
 * Leaves (Plate 207, Fig. 31) 1¼ inch long, 2¼ inches broad, coriaceous, greyish beneath ; lobes ovate, obtuse. Petiole without latex. (See description, p. 665.)


 * 8. Acer creticum, Linnzus, Greece, Crete, Lycia.
 * Leaves (Plate 207, Fig. 32) ¾ to 1½ inch long, coriaceous, variously three-lobed, or with the lobes obsolete on some of the leaves, short-stalked, cuneate, or rounded at the base; margin non-ciliate ; bright-green and glabrous beneath ; petiole without latex. Fruit small, glabrous ; wings parallel and not diverging.
 * A small tree, scarcely exceeding 30 feet in height, introduced in 1752. Old trees exist at Syon (mentioned by Loudon), Barton, and White Knights.
