pubescence being silky-woolly instead of appressed-hairy, and in the shaggy- 
hairy pods. Silver City, N. M., May 4, 1930. East of Lordsburg, N. M., 
May 5, 1930. These plants were low and widely Jers: and with short 
pedun cles. Ramse ey Canon near the mouth, Apr. 6 , 1930. These plants 
were tall, two feet high and mostly erect. This species seems to be more 
common than mollissimus. 
Astragalus Earlei, Greene. This species looks like a small-fllowered 
form of Bigelovii with narrower pod (lance-oblong) and barely short-pubes- 
cent pods. The pubescence of the whole plant is short and dense. Alpine, 
Tex., Apr. 20, 1930; Marathon, Tex., Apr. 24, 1930. 
Astragalus marcidus Greene. Whole plant softly shaggy-long-woolly 
even to the . Flowers small and purple in a dense and elongated spike. 
Pods depressed-globose and barely apiculate, 4-6 mm. long, concealed by the 
calyx. This is a counterpart to A. Matthewsii but the pods only about a 
quarter as large 
these species lead one to think vi the Mollissimi group is very 
variable and that the species are confluen 
Astragalus crassicarpus Nutt. nine, Tex., Apr. 26, 1930. This is a 
species with a single erect and thick with a crown of many stems 
spreading in all directions, the lateral ones ee or prostrate in fruit. 
The pods vary from spherical to broadly oblong. This includes Rydberg’s 
Geoprumnon succulentum and A. a The Texan plants are unusually 
small, but with the characteristic root 
Astragalus Plattensis Nutt. I should judge ” this includes A. pachy- 
carpus G., which I referred to crassicarpus as a variety in my mono- 
: Torrey and Gray did not know anything aren the root system of 
= plant, but the shape and character of the pod would place it with Platten- 
However the status of the species can be determined at once if it belongs 
ra Plattensis, for this species is entirely different from crassicarpus whose 
root is single, fleshy and erect and with all the stems coming out from the 
escent at first. The habit of the species is much the same as A. agrestis 
( bie hcon na Ozona, Tex., growing with A. giganteus, on mesas among the 
Astragalus humistratus Gray. This is the white-pubescent early form 
which Wooton and Standley call albulus. Organ pass, N. M., May 3, 1930.
