MONOECIA— POLYANDRIA. Corylus. 157 



quently much enlarged, permanent ; ijiner superior, very 

 minute, obsolete, deciduous. Cor. none. Germ, very 

 small, ovate, with rudiments of 2 seeds. Styles 2, very 

 short. Stigmas prominent, awl-shaped, coloured, finely 

 downy, deciduous. Nut ovate, with a broad scar, bony, 

 not bursting, a little compressed and downy at the top, 

 scarcely pointed, of 1 cell, internally spongy or filamen- 

 tous, invested with the greatly enlarged, coriaceous, 

 jagged, downy outer calyx, whose base is succulent. 

 Kernel solitary, rarely 2, ovate, with large, half-ovate 

 cotyledons, without a separate albumeii ; embryo oblong, 

 at the top of the seed. 

 Small trees, more or less downy, with round branches, and 

 stalked, alternate, roundish, serrated, deciduous leaves^ 

 coming after the naked catkins and jlavoer-buds. Nuts eat- 

 able. The forms and proportions of the calyx of the fruit, 

 I think, indicate distinct species, permanent from seed.

Tree. March, April. 



A small bushy tree, with copious branches, hairy, or glandular, 

 when young. Leaves 2 or 3 inches wide, doubly serrated, light 

 green, downy, especially beneath. Barren catkins terminal, 

 clustered, or panicled, greyish, long and pendulous, opening in 

 the early spring, before the leaves appear, and indeed formed 

 during the preceding autumn. The ovate scaly buds, contain- 

 ing the fertile j^o;t>ers, become conspicuous at the same time, by 

 their tufts of crimson stigmas. The nuts, 2 or 3 from each bud, 

 are sessile, roundish-ovate, half covered by the jagged outer 

 ca/?/x-of their respective j^owers, greatly enlarged, and perma- 

 nent.
