Stems six to sixteen inches long. Heads and flowers about the size of those 

 of the small form of T. gracilentum, to which species it is allied. Ovary twc- 

 ovulate, seeds single. 



Astragalus L. 

 A. curtipes, n. sp. (§ Phaca, * Inflati.) 



Minutely canescent, at length glabrate, a foot high ; stipules connate, oppo- 

 site the leaf ; leaflets twelve to sixteen pairs narrowly oblong, retuse petiolulate, 

 glabrous above ; raceme in fruit short ; calyx-teeth slender, subulate, slightly 

 shorter than the campanulate tube ; legume membranaceous, inflated, glabrate 

 (\% inches long,) semi-ovoid, (the ventral suture nearly straight, the dorsal 

 very gibbous,) scarcely acute at either end, jointed to a rigid stipe, which does 

 not exceed the tube of the calyx. 



Dry hill sides, San Luis Obispo. Corolla not seen. 



A. oxyphysus, n. sp. (§ Phaca, * Inflati.) 

 Tall, very softly canesceu-villous , stipules small, scarious, distinct ; leaflets 

 8-11 pairs, oblong; peduncles much surpassing the leaf; raceme elongated; 

 bracts small and subulate ; teeth of the silky calyx subulate, half the length of 

 the cylindraceous tube ; corolla white or greenish ; legume obovate-acuminate, 

 the base attenuate into a recurved stipe which somewhat exceeds the calyx. 

 Monte Diablo Range, near Arroyo Puerto, on dry hills. 

 A most distinct and striking new species. 



A. Breweri, n. sp. 



Aliled to A. tener Gray, Rev. Astrag. (Phaca astragalina, var. ? Hook, and 

 Arm, and probably A. hypoglottis, var. strigosa, Kellogg,) but more branched 

 from the annual root, and with broader leaflets, (4-5 pairs, oblong-obcordate) ; 

 head 5-7 flowered, compact ; immature legume globose-ovate, silky-canescent, 

 not stipulate, erect, six-ovulate, one-celled, the dorsal suture slightly intruded. 



Fields in Sonoma Valley, April. Common. 



Dr. Ayres read letters from Mr. A. Garrett, and presented the

 The height of the body is a trifle less than one-third of the total length. The 

 upper profile rises in a convex line from the snout to the occipital region, whence 

 it suddenly ascends in a nearly vertical curve, giving that portion of the fish a 

 strongly gibbous appearance. The body rapidly tapers posteriorly, though pre- 

 serving a slightly convex outline. The head enters nearly four and a half times 

 in the entire length. The eyes are large, sub-circular in shape, even with the
