A DECADE OF NEW POMACEX. 129 
Collected at Los Pinos, southern Colorado, 16 May, 1899, 
by C. F. Baker. Much like the northern A. alnifolia as to 
leaf-outline, but totally unlike it by its short, stiff, spreading 
branches, puberulent branchlets, and small leaves and 
flowers. 
A. GonMANI. I assign this name, in commemoration of 
Mr. M. W. Gorman's abundant and fruitful researches in 
Alaska, to the Alaskan shrub, or small tree which has passed 
under the name of A. alnifolia. It is distinguished from 
that species by a more slender habit, larger and relatively 
longer oval, or oblong-obovate slender-petioled leaves, its 
long loose perfectly glabrous racemes, and a very character- 
istic calyx. This organ is externally quite glabrous and 
distinctly glaucous; its limb is notably dilated under the 
insertion of the petals into a broad saucer-shaped rim; and 
the lanceolate segments, either erect or somewhat spreading, 
are longer than all the rest of the calyx, and are tomentu- 
lose within. The fruit in this species makes an approach 
to the pyriform in outline and is glaucous. 
My best specimens of this very beautiful species were ob- 
tained by Mr. Gorman, at Yes Bay, Alaska, in 1895, the 
flowers having been gathered on the 16th of June, the fruits 
on the 6th of September. 
Sorpus DUMOSA. Shrub with clustered but slender and 
very erect stems 5 to 8 feet high ; bark red, white-dotted and 
glabrous, except on the growing shoots, in these rather 
densely puberulent or pubescent with short white hairs: 
leaves small, only 3 to 6 inches long and the leaflets in 
mostly 5 pairs, the rachis villous-pubescent, but leaflets 
quite glabrous on both faces, oblong or oblong-lanceolate, 
ł to 1} inches long, evenly and lightly serrate from below the 
middle, the serratures rather appressed, indistinctly gland- 
tipped, the apex of the leaf abruptly attenuate to a long 
slender point: winter buds canescently villous : cymes small, 
narrow, low-pyramidal rather than flat-topped: pedicels 
and calyx puberulent.
