Description of a New Species of Allium. 



BY A. KELLOGG, M.D. 



Allium L. 



Allium parvum Kellogg. [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-lanceo- 

 late sub-acute ; genitals included, iDner 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 per- 

 sistent, 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 0. 

 Dorr. The leaves are two to three times the leugth 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.
