and a half inches long, villous and ferruginous^ thickened 

 under the leaf. Racemes axillary, shorter than the leaves. 

 Flowers pedicelled. Peduncles and pedicels ferruginous. 

 Drupe oval, of the form of an olive but smaller, with a 

 single rather smooth nut, which generally contains but one 

 perfect seed ; sometimes there is a second smaller, and the 

 vestiges of the partition and abortive ovula can almost always 

 be observed. Seed oblong, pointed above. Albumen con- 

 form; Embryo inverse, extending nearly the whole length 

 of the albumen. Cotyledons flat, oblong with a distinct 

 nerve along their middle. Radicle superior clavato-cylin- 

 drical, much shorter than the cotyledons. 



Obs. — I have not seen the flowers of this species, but its 

 fruit and general resemblance to the preceding leave no 

 doubt as to the genus, and its characters are sufficiently 

 marked to distinguish it from the others.

A tree of moderate size. Branches roundish, furfurace- 

 ous with appressed stellate hairs. Leaves alternate, petiolate, 

 rhomboidal-ovate, often approaching to three-lobed, long 

 acuminate, rounded and biglandular at the base where the 

 petiole is inserted within the margin, remotely denticulate 

 towards the apex, smooth and green above, hoary and tomen- 

 tose beneath. The young leaves have stellate deciduous 

 hairs on the upper surface. Petioles long. Stipules none. 

 Panicles terminal, or from the bifurcations of the branches,
