5. Acer Fargesit, Rehder.’ Central China. 
Leaves 3 to 4 inches long, ? 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 14 foot high in six years. 
6. Acer Davidi, Franchet.? Central China. 
Leaves 3 to 4 inches long, 14 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. 
6a. Acer crateagifolium. See No. Io. 
Leaves of this species, without lobes, are distinguishable from 4. Davidi by 
the absence of the conspicuous axil-tufts on the lower surface. 
II. Leaves simple, three-lobed. 
* Leaves entire in margin. 
7. Acer monspessulanum, Linneus.. Southern Europe, North Africa, Asia 
Minor, Caucasus. 
Leaves (Plate 207, Fig. 31) 14 inch long, 2} inches broad, coriaceous, greyish 
beneath ; lobes ovate, obtuse. Petiole without latex. (See description, p. 665.) 
** Leaves minutely crenulate. 
8. Acer creticum, Linnzus, Greece, Crete, Lycia. 
Leaves (Plate 207, Fig. 32) } to 14 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. 
xe Leaves irregularly toothed. 
9. Acer trinerve, Dippel. A juvenile form of the Chinese Acer trifidum, Hooker 
et Arnott, cultivated in Japan. 
Leaves 23 inches long, 2 inches broad, variable in lobing ; lobes acuminate ;
