membranous, inflated, an inch long when fully developed, 

 minutely pubescent, oval, apparently circular in cross-section, 

 with a short triangular point, very slightly pointed at base, 

 horizontal, dorsal suture scarcely evident, generally sulcate 

 slightly dorsally, ventral suture impressed about a line deep in 

 the middle of the pod and seed-bearing for half the length of the 

 pod, not impressed at base or apex, deeply sulcate ventrally to 

 about one-third the depth of the pod, seeds small, many; young 

 pods more pointed and hoary pubescent. 



Other specimens from Scammon's Lagoon, Lower California, 

 have oblanceolate leaflets, six lines long, neither truncate nor 

 acute, twelve to fifteen pairs; no petiole; leaf three to six inches 

 long; calyx, bracts, and spikes the same as above; flowers light 

 purple, sides of banner and tip of keel dark; blade of keel two 

 and one-half lines long, bent from base of blade to the blunt tip 

 into one-third of a circle, very short and thick; broadly lanceolate 

 wings, little ascending and a little longer than keel; banner ovate 

 in outline, large, curved in an arc of a circle beginning at tip 

 of calyx teeth, apex erect, two lines longer than keel; pods 

 inclined to be ovate and more pointed, minutely pubescent, ICvSS 

 deeply sulcate, but otherwise the same. The heads resemble 

 A. adsurgens. Manifestly allied to A. diphysiis and lentiginosi/s, 

 despite the one-celled pod, but nearest to A. oocarpns. The 

 whole section to which this belongs, from A. curtipcs to A. 

 Doi/glasii, is in great need of careful and extensive field studies. 

 I have no doubt that there are twice as many species recognized 

 as exist. This might be A. vestiius as far as the description 

 goes, for some of the flowers might be called ochroleucous if 

 taken alone. 



ly Astragalus anemophilus Greene. (Includes A. Migiielensis 

 Greene.) This is very closely related to A. ca7ididissimits, and 

 may prove to be identical with it, and is quite likely to be A. 

 vestitiis. It differs from the former so far as the type goes in the 

 stipules being connate opposite the petioles, and in the white- 

 woolly pubescence. The flowers are too immature to determine 

 what they are. The pubescence of A. candidissimiis is woolly or 

 tangled on the calyx, but elsewhere is of straight or slightly 

 tangled hairs which are appressed. The leaflets of this species
