whorl corresponding with the flowers ; hirsute, with long white

Cal3^x campanulate, wooly, hirsute ; segments oblong or sub- 

 spatulate, obtuse, tipped by a red gland. 



Upper lip of corolla deeply bifid, each segment emarginate, 

 nearly equal the lower. 



Corolla tube curved very slightly, gibbous at the base above. 

 (See No. 1 in the figure.) No. 2 represents the corolla of C.

This species of Collinsia is frequently met with in this vi- 

 cinity. The Society are under obligations to Mr. Dunn for 

 the specimens herewith presented. 



The following Allium is found in the vicinity of Oakland and 

 about the Bay of San Francisco. We are indebted to Mr. 

 Dunn for the specimen here figured and described : 



Allium unifolium (Kellogg). — Fig. 35. — Scape long (a foot 

 ormore in length), robust, terete, ascending from an oblique 

 bulb ; rhizoma repent. 



Solitary leaf, radical, sheathing beneath the soil, shorter 

 than the scape, falcate, plane or slightly convex above ; midrib 

 somewhat prominent below, obsoletely seven-nerved, ancipital, 

 margins entire, subacute. 



Spathe connate at tlie base, two-leaved, very thin, scariously 

 transparent, three to seven-nerved, broadly ovate, acuminate, 

 or ovate-oblong acuminate. 



Umbel convex, fifteen to twenty-flowered, capsuliferous, ped- 

 icels an inch to an inch and a half long, somewhat obconically 

 thickened at the base of the flower. 



Flowers large, pink (of cheerful, lively hue) pctaloid divis- 

 ions rather thick and fleshy, spreading, rotate campanulate, 

 slightly gibbous at tlie greenish base ; midrib also green below 

 on the back, red above ; three outer sepals oblong-ovate, sub- 

 acute (or subemarginate) plane, entire, three inner narrower, 

 apex emarginate ; perianth about one-third longer than the 

 stamens and pistil. 



Filaments simple, subulate, the outer slightly narrower, fila- 

 ments at first shorter, at length equal, the inner a little dilated 

 at the base. 



Style simple, subulate, as long as the stamens.
