632 MONOECIA POLYANDRIA. JuglttnS, 



Young shoots clothed with minute, gold-coloured scales. 

 Leaves alternate, sub-opposite, and abruptly pinnate, from 

 six to twelve inches long-. Leaflets from three to four, or 

 from five to thirteen, short-petioled, obliquely lanceolate, ob- 

 tusely acuminate, entire, firm and smooth, from three to six 

 inches long-, by one or two broad. Petioles round, when 

 they first unfold, scaly like the other tender parts. Panicles 

 axillary and terminal, shorter than the leaves ; composed of 

 many, filiform, simple male aments, and a few similar female 

 ones, all are clothed with the minute yellow scales above men- 

 tioned. Male FLOWERS, ^ca/es of the anient solitary, one- 

 flowered, scarcely to be distinguished from the pedicels, and 

 clothed with the yellow scales just mentioned. Calyx four- 

 leaved ; leaflets roundish, concave, and so much separated as 

 to appear in some measure four corollets. Corol none. Fi- 

 laments twelve, very short, inserted on the base of the leaflets 

 of the calyx. Anthers large, two-lobed. Female flowers. 

 Scales of the anient, and calyx as in the male, only larger and 

 more distinct, both are permanent ; the former increasing. 

 Germ inferior, turbinate, covered with little yellow scales, 

 one-celled, containing a single ovulum, attached to the bot- 

 tom of the cell. Style scarcely any. Stigma spread over the 

 top of the germ, somewhat two-lobed, with the lobes rather 

 lacerated. Nut round, very hairy, the size of a large pea, 

 crowned with the permanent calyx, and resting in the en- 

 larged scale of the anient, the three lobes of which are now 

 increased into three long, lanceolate obtuse, scariose wings, 

 the middle one of which, as in the germ, much larger, some- 

 times the inner margin of the scale is extended in the ripe 

 state, into a two-lobed, short, broad wing, one-celled at top, 

 which cell becomes four-lobed at bottom, (semi-quadrilocu- 

 lar,) two-valved ; valves very hard. Seeds solitary, four- 

 lobed. Lntegument single, thin, of a light brown. Peris- 

 perm conform to the seed, scanty, sebaceous. Embryo 

 inverse. Cotyledons two, intricately folded up in the four 

 lobes of the cell of the nut : when veeetation has advanced so
