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, generaily 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, less 
deeply sulcate, but otherwise the same. ‘The heads resemble 
A. adsurgens. Manifestly allied to A. diphysus and lentiginosus, 
despite the one-celled pod, but nearest to 4. oocarpus. The 
whole section to which this belongs, from 4. curtipes to A. 
Doug lasii, 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. vestitus as far as the description 
goes, for some of the flowers might be called ochroleucous if 
taken alone 
Astragalus anemophilus Greene. (Includes 4. Miguelenszs 
Greene.) This is very closely related to 4. candidissimus, and 
may prove to be identical with it, and is quite likely to be 4. 
vestttus, 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 4. candidisstmus is woolly or 
tangled on the calyx, but elsewhere is of straight or slightly 
tangled hairs which are appressed. The leaflets of this species
