1905] INNELSON—ROCKY MOUNTAIN PLANTS 67 
most of the leaves elliptic in outline, incisely serrate, with rather small 
teeth extending to the middle or sometimes nearly to the base, nearly 
glabrous above from the beginning, lightly floccose woolly beneath 
when young as are also the slender petioles: inflorescence few- 
flowered, quite open in blossom and more so in fruit: calyx somewhat 
woolly-pubescent, its lobes deltoid-triangular, shorter than the tube, 
lanate on the inner face: petals narrowly oblanceolate, ig 
long: mature fruit not known, the half-grown fruit spherical. 
This will also have to be considered as a segregate from A. alnifolia, from 
which it differs noticeably in its elliptic leaves, the teeth of which are smaller 
and sharper and point toward the apex. The woolly pubescence of leaf and 
flower at once calls attention to this as distinct from the thick-leaved glabrous 
A. alnifolia. A. elliptica seems to be a species of wet places in the mountain 
parks and open stream banks. The species is again noticeable because of its 
few large flowers which are well exsérted from the leaves. It is as handsome 
a species when compared with A. alnifolia as is A. florida when compared with 
A. Cusickii. 
I take as the type L. N. Goodding’s no. 1447, Beaver a Larimer Co., 
Colo., July 4, 1903. The following also seem to belong here: G. 
1036, “Milford, Utah, June 5, 1902; Baker, Earle, and Tracy, no. ‘197; Bob Creck, 
Colo., June 28, 1808; possibly the following also: Jones, no. 1447, City Creek 
cafion, Utah, June 5, 1880; Baker’s West Central Colorado Plants, rgot, nos. 
47 and 260 (in my set distributed unnamed).
