RARE WYOMING PLANTS. 53 



Streptanthus cordatus Nutt. The specimens secured of this 

 agree very closely with the description,* even to the bristles on the 

 teeth and petioles of the radical leaves. Flowers were not secured, 

 but the fruit-bearing racemes are dense, from 10 to 20 cm. long; 

 pedicels short, stout ; pods divaricate, curved ascending, 4 to 6 cm. 

 long, about 4 mm. wide. Collected near Evanston, which Dr. 

 Greene f thinks must be near the type locality. The pods on these 

 specimens, being divaricate-ascending instead of deflexed or down- 

 wardly curved, do not accord with those of the specimens that Dr. 

 Greene considers typical; they differ even more from his S. crassi- 

 folius in the broader pod as well as in the broader cauline leaves. 



Stanleya bipinnata Greene Erythea,Iv. 173. The specimens 

 represented by the following number are probably the first that have 

 been secured since the type specimens were collected by Professor 

 Greene at Rock Creek in this state. The present specimens proba- 

 bly do not have. the leaves so fully dissected as the type. On the 

 bluffs of North Vermillion Creek, July 17 (3,562). 



Acer grandidentatum Nutt. Small clumps of this shrubby 

 Utah maple were found on one of the foothills near Evanston 

 (2,952). 



Trifolium Rydbergii Greene, Pitt. Ill, 222 (1897). T. longipes 

 reflexum Aven Nelson, First Rep. Fl. Wyo. 94 (1896). A peculiarly 

 fine species widely distributed in this state; Big Creek, Carbon 

 County (3,971). 



This state possesses a marvelously rich Astragalus - flora, the 

 University^ collection already containing upwards of 45 species. 

 Among these the following are noteworthy: — 



Astragalus arietinus Jones. Collected at Evanston (2,968). 



Astragalus Bodini Sheld. This seems to have been reported 

 so far only from this state. It is very abundant in wet meadows*. and 

 is a good forage- plant; Laramie (3,395). 



Astragalus glareosus Dougl. From near the probable type 

 locality. Mr. Rydberg, who kindly compared these specimens with 

 the Columbia Herbarium material, pronounces these typical, and he
