28 Contributions to Western Botany. [zOE 



"both sutures prominent externally, pod three lines long; lower 

 stipules large and hyaline and densely imbricated; leaflets five to 

 eight pairs two to three lines long, elliptical and appressed silky; 

 leaves two inches long, root woody and large. This seems to be 

 near to A . miser. This description is drawn from the type collected 

 on the Gila River, by E. L. Greene. I do not attempt to give a 

 full description, as the other characters are given by Mr. Greene. 



Astragalus insularis, Kellogg. I do not know where this was 

 first published. Annual or flowering the first year. The small 

 plants have the habit of A. Geye^-i and a remote resemblance to 

 A. triflonis. Many-branched at the summit of the root and 

 rather slender, lateral branches probably prostrate or ascending, 

 and the central ones erect or nearl}' so. Flowers two lines long, 

 keel, wings, and banner nearly equal, not curved; very campanu- 

 late or globose calyx sessile and as long as the subulate- 

 triangular teeth, calyx and teeth scarcely over a line long in all, 

 calyx reflexed in fruit; pods broadly ovate, sessile, membranous, 

 one-celled and not sulcate, sutures scarcely visible, pod much 

 inflated, about five lines long, rounded at base and with a 

 triangular laterally flattened, sharp apex which is one or two 

 lines long, the beak is flattened so as to be no thicker than 

 paper in the second form given below, cross-section of pod 

 apparently circular; peduncles one to two inches long, rather 

 stout, shorter than the leaves, three to six-flowered, racemosely 

 and remotely on the upper half of the peduncle; leaves with 

 three to five pairs of elliptical-linear and apiculate leaflets which 

 occur on the upper half of the rachis or common petiole; whole 

 plant, even to the pods, minutely pubescent. Cedros Island, 

 collected by Dr. Veatch, 1877, June 4th. Another form, if such 

 it be, is the upper part of a stem that may have been a foot or 

 two long; it has seven to nine pairs of acute leaflets, six lines 

 long, no proper petiole; leaves four inches long; peduncles two 

 and one-half to three inches long and stout; pods globose but 

 with the peculiar beak three lines long. Cedros Island, Dr. 

 Veatch. This species seems to belong near A. macrodon. A. 

 Pondii Greene, Pittonia, i, 288, is the same so far as the 

 published description goes.
