The greater part of the accompanying drawing of this entirely new genus, was made from imperfect specimens 
gathered on the Columbia by Mr Douglas and Dr Scouler in 1825. It has since been sent me, in various 
states, from the “margins of pine woods,’’ in the same country, by Dr Gairdner and Mr Tolmie, and from 
these specimens the drawing was completed. It now appears in Mr Douglas’ Californian collection; and I have 
lately received the same plant from Mr Nuttall, gathered by that gentleman on the Columbia, and bearing the 
ms. name of Nuttallia cerasiformis of Torrey and Gray, a name which I have the greatest pleasure in thus per- 
petuating. Nor could the name be attached to any plant with greater propriety than to one inhabiting a 
district of country where that gentleman has so eminently signalized himself by his recent laborious researches 
and discoveries. We here subjoin Mr Nuttall’s description, drawn up on the spot, as copied from his ms. 
by my friend Dr Gray, and which shows how' well he distinguished all its remarkable features. 
“ A small forest-tree, about the size of Amelanchier Botryapium, exhaling a faint scent of Bitter Almonds 
with a smooth brown bark on the branches, and alternate, oblong, entire, thin leaves. Racemes filiform, 
connected at the base with a branchlet, both included in the common bud. Leaves alternate, entire, 
cuneate-oblong, apiculated, and attenuated below into a short petiole, more or less pubescent or glabrous 
beneath ; the same bud producing both leaf and raceme. Raceme pendulous, and, with the white flowers 
and unguiculate oblong petals, resembling Amelanchier Botryapium. Bracts membranous, narrow, and 
acuminated. Male calyx campanulate, half-way 5-cleft. Segments lanceolate. Stamens about 12-15, in- 
serted on and below the margin of the calyx. Female calyx dividing circularly towards the base ; the base 
remaining beneath the fruit. Stamens minute and rudimental, fewer. Germs 5, roundish, 2-3 usually soon 
abortive ; styles filiform, deciduous ; stigma small, 2-lobed. Germens for some time gibbous, the mature 
drupe at length nearly straight, the internal indehiscent suture scarcely visible ; pulp a mere succulent' 
blackish-brown skin, furnished with a bloom. Nut 1-seeded ; no perisperm or albumen. Embryo straight, 
the radicle inserted towards the summit of the fruit. The fruit is greedily eaten by robins and other baccivorous 
birds, though almost bitter to the taste, and with the heavy odour of the bitter almond.’’

1. parvifolia {Nutt.) ; foliis late obovatis dentatis (junioribus praecipue) 
subtus pubescenti-birsutis, floribus geminatis recurvis, fructus cauda longissima. Nutt, in 
Herb. Hook. — Torr. et Gr. FI. ined . — Hook. Ic. PI. t. 323. 
This species comes so very near the description of the Mexican C. fotJiergilloides, H, B. K. Nov. Gen. 
Am. t. 559, that until we examined specimens lately sent by Mr Hartweg, we hesitated whether it should 
not be referred to that plant. All the specimens, however, from Mr Douglas, as well as one collected by 
Mr Nuttall on the Platte River, have the leaves smaller, and more downy beneath, than Humboldt’s species, the 
flowers not clustered, but geminate and recurved, the fruit larger, and the cauda much longer and more 
plumose. A second species, found by Mr Nuttall (C. hetuloides, Nutt. ms. in Herb. Hook., and Hook. 
Ic. PI. t. 322), is also quite distinct from the Mexican plant ; while a third species, C. ledifolia (Nutt, 
ms. in Herb, nostr., and Hook. Ic. PI. t. 324), is extremely different from all the rest. 
■With regard to the genus itself, it must rank very close to Pursliia, from which it scarcely differs, except
