496 CXXIV. CUPULIFER^. Corylus. 



abortive rudiments ; sty. 6 ; nut mostly 1 -seeded, invested with the 

 enlarged, echinate involucre or cupule. — Trees and shrubs. Lvs. mostly

1. C. Vesca. Gaert. /?. Americana. Michx. (Fagus Castanea. Linn.) 

 Chestnut. — Lvs. oblong-lanceolate, acuminate, mucronately serrate, smootn 



both sides. — Abundant in particular districts throughout the U. S. It is a lofty 

 tree, with a large, straight trunk. Leaves quite large (6 — 9' long and i as 

 wide), with large, uniform teeth, mucronate with the prolonged, straight veins. 

 Aments as long as the leaves and so numerous as to impart their yellowish hue 

 to the whole tree when in blossom. The nuts are about 3 together, of a pecu- 

 liar brown, villous above, enclosed in the enlarged cupule or burr which is beset 

 on all sides with strong, compound, acute .spines. Timber coarse-grained, 

 strong, elastic, light and very durable, hence much used for posts, &c. July, — 

 The nuts are smaller, but sweeter than those of the European variety (the Span- 

 ish chestnut.)

 with purple foliage, silver foliage, &c. (Sec garden catalogues.)
