 President in the Chair. 

 Dr. Kellogg read the following paper : 



Leivisia alba (Kellogg). — Pig. 36 — White Spatulum of the na- 

 tives. Leaves succulent, linear-spatulate, obtuse, grooved be- 

 lovr the middle, the membranous margins waved, base similar 

 and expanded ; the upper half thickened and flattened, with 

 a depressed line along the midi'ib ; surface roughened and cor- 

 rugated, glaucous, green, turning to red in withering. 



Scapes succulent, somewhat shorter than the leaves (two to 

 three inches in length), subterete, articulated at the crown of 

 the root by a constricted base, also above the middle, where 

 they are involucrate (?) with a whorl of about seven unequal 

 leaves, the two leaves opposite the largest diameter of the 

 scape about an inch in length, dentate ; all grooved above, 

 convex on the back, linear, obtuse, articulated at the insertion. 



Sepals eight, somewhat obovate, emarginate, base and mid- 

 dle portion thick and fleshy, margins thin, sometimes slightly 

 crenulate above, faintly colored. 



Flowers white, about sixteen-petaled, subequal, oblong-ovate, 

 obtuse or emarginate, base cuneate into an obsolete incurved 

 claw, summit crenulate. 



Staraens extrorse, short ; anthers pink-colored ; style eight- 

 parted or eight filiform. 



Root large, fusiform, branching below, the loose outer bark 

 dirty white, the inner portion snowy white and farinaceous. 



Astragalus hypoglottis (var. strig-osa, Kellogg).— Fig. 37. — A 

 small plant with relatively large purple flowers in condensed 

 spikes or heads on long axillary peduncles. A plant of rather 

 unusual beauty. The calyx deep purple, petals from purple 

 shading to white on the extreme points and margins. 



The specimens in this vicinity have neither " tomentose " nor 

 " villous " pods, but quite glabrous. It evidently varies much, 

 for hypoglottis proper has one-seeded cells, and var. polgspermus 

 three to four-seeded cells, while this has six to eight ; in one 

 specimen the leaves are acute, while others are emarginate, 

 besides other particulars uniting the characters of both. 



Stem slender, slightly decurrent, angled, branches ascending 

 from the base, hirsute throughout with black, appressed hairs'. 



Stipules cohering with each other underneath the petioles, 

 triangular-ovate, acute or acuminate, margins conspicuously 

 ciliate with black appressed hairs, membranaceous, often cut- 

 dentate.
