126 MISSOURI BOTANICAL GARDEN. 
ASTRAGALUS LOTIFLORUS Hook. 
(A. elatiocarpus Sheld. Bull. Minn. Geol. and Nat. Hist. 
Surv. n. 9: 20. 1894, at least as toformabrachypus. A. 
lotiflorus formae brachypus and pedunculosus of Gray.) 
Abundant on all the gentle slopes and along the back- 
bones of the mounds. When I first collected this species 
in August, 1893, it was in fruit, with very short or no 
peduncles, which led Dr. Trelease and myself to place it 
with the forma brachypus of Gray. 
On April 20th, 1894, I collected it again, but this time 
it was in flower and with very long peduncles. ‘This led 
me to write Dr. Trelease the statement that the earlier 
flowers were very long peduncled and infertile, while later 
on it produced fertile flowers on very short peduncles; for 
some last year’s fruits were still on some plants and no 
sign of long peduncled fruit had been observed the year 
before. On June Ist, I again collected the plant and this 
time it had fruit on both long and short peduncles On 
July 11th, the long peduncles had mostly dropped off the 
plants, leaving only the short peduncled fruit. This 
clearly shows that the species has both long and short- 
peduncled fruit, and that the formae brachypus and pe- 
dunculosus of Gray occur on the same plants. I strongly 
suspect that the Astragalus elatiocarpus of Sheldon is an 
entirely different species. (Watson Nos. 198, 199, 200 
and 203.) 
Spres1a Lamperti (Pursh) Kuntze. 
Common on the steep precipitous sides of the highest of 
the mounds. The roots are exceedingly long and tough, 
and often are seen hanging over the bluffs from which the 
earth has crumbled away and left them. (Watson No. 
204.) 
GLycyRRHIZA LEPIDOTA Pursh. 
Common at the bases of the mounds in bare and some- 
what gravelly ground. (Watson No. 205.)
