632 The Trees of Great Britain and Ireland 



5. Acer Fargesii, Rehder.' Central China. 



Leaves 3 to 4 inches long, f to i 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 i^ foot high in six years. 



6. Acer Davidi, Franchet.^ Central China. 



Leaves 3 to 4 inches long, i^ 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 cratcegifolium. 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, 



IL Leaves simple, three-lobed. 



* Leaves entire in margin. 



7. Acer monspessulanum, Linnaeus.' Southern Europe, North Africa, Asia 



Minor, Caucasus. 

 Leaves (Plate 207, Fig. 31) i^ inch long, 2\ inches broad, coriaceous, greyish 

 beneath ; lobes ovate, obtuse. Petiole without latex. (See description, p. 665.) 



** Leaves minutely crenulate. 



8. Acer creticum, Linnaeus. Greece, Crete, Lycia. 



Leaves (Plate 207, Fig. 32) f to i^ 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. 



*** Leaves irregularly toothed. 



9. Acer trinerve, Dippel. A juvenile form of the Chinese Acer trifidum, Hooker 



et Arnott, cultivated in Japan. 

 Leaves 2^ inches long, 2 inches broad, variable in lobing ; lobes acuminate ;
