PAYSON—MONOGRAPH OF THE GENUS LESQUERELLA 141 
associated with L. lasiocarpa to which it bears little resemblance 
in minor details. Petioled stem-leaves as opposed to auriculate 
ones, elliptical rather than cireular pods, and immarginate instead 
of winged seeds are points o: difference between the two species 
of this section. 
No authentie material of Schauer's plant has been seen, but 
the original description of Vesicaria argentea agrees so closely 
with Synthlipsis lepidota Rose that there seems no doubt as to 
the identity of the type. Watson referred this plant to Les- 
querella doubtfully, and Gray remarked that when the mature 
fruit was known it might prove to be a species of Synthlipsis. 
Like L. lasiocarpa, however, this plant shows no affinity with 
Synthlipsis Greggii and possesses no characters to keep it out of 
Lesquerella.

Vesicaria frigida Turez. Bull. Soc. Nat. Moscou 27: 296. 
1854. 
Cespitose perennial, stellate-pubescent throughout; lower 
part of the stem unifoliate, the rest naked, sparsely stellate; 
radical, cauline, and leaves of the sterile shoots tongue-shaped, ob- 
tuse, quite entire, grayish silvery; petals unknown; sepals saccate 
at the base; filaments dilated ; placental and valvular nectar glands 
rather large; terminal raceme many-flowered; pedicels erect, 
exceeding the pods; pods sessile, valves inflated laterally, sub- 
impressed in the middle, dorsally 1-nerved; styles half as long 
as the pods; septum entire, longitudinally nerved; ovules num- 
erous, pendulous, funiculi filiform, almost entirely adnate to the 
septum; seeds immarginate, compressed parallel to the septum; 
cotyledons accumbent. 
Distribution: collected by Funck and Schlim in the Sierra 
Nevada in the province of Merida, Venezuela, at an altitude of 
11,000 feet. 
This plant is known to me only by the original description 
from which the above was compiled. The plant is evidently a 
Lesquerella and undoubtedly to be associated with L. Schaueriana 
because of the obcompressed pods.
