Description of a New Species of Allium. BY A. KELLOGG, M.D. ALLIUM L. _Allium parvum_ Kellogg. [FIG. 13.] [Illustration: FIG. 13.] Scape short, naked, narrowly ancipital; leaves two, long linear-lanceolate, acute, apex recurved, plain above, much attenuated towards the subterranean base, which is somewhat canaliculate; lamina from five to ten-nerved, margins remotely subscabrulose; flowers pale, purplish, about eight; umbel convex, pedicels triangular, thickening upwards, about as long as the flowers, nerves of the sepals distinctly purple to the tips; three outer sepals longer and broader, erect, entire, oblong, somewhat obtuse, carinate; the three inner linear-lanceolate sub-acute; genitals included, inner stamens slightly longer, anthers pale, blueish, filaments simple, expanded at the base; style equal, stigma acute, simple (or obsoletely lobed); capsule in outline obcordateley trigastric, embryo granular (mature fruit not observed), appears to be somewhat substipitate, as seen in the figure, the three cells somewhat grooved on the back; spathe persistent, two-parted, ovate, sub-acute, about eleven-nerved, hyaline, and lilac purple; bulb ovate, oblong, externally loosely coated with light-colored, smooth-nerved membranaceous tunics. The scape is often found only an inch above ground, as in the recent specimens from Mount Davidson by Mr. Herbert C. Dorr. The leaves are two to three times the length of the scape. Our figure is from a cultivated specimen furnished by Mr. H. G. Bloomer, from bulbs sent us some years since by Mr. Andrew A. Veatch, from Washoe. This is the largest form of it we have yet seen. The bulbs, however, under culture, are often three or four times the size here represented. It has none of the garlic odor so common in this genus. REGULAR MEETING, AUGUST 17TH, 1863. Dr. Trask in the Chair. Present, eleven members. Donations to the Cabinet: Three boxes of ores from various localities, presented by Dr. Trask.
