ORT only by the narrow bases of the iia: rth 
characters taken from the shape of the ovary are variable ; : 
whether the original European G, detonsa is distinct, I can- 
not at present ascertain.

On the alpine summit of 
Mount Flora, in the Sno 
Range, Colorado, Dr. Parry ; 
flowers September. — A perenni- 
al, 2-4 inches high; radical leaves 
1 inch long and 3-4 lines wide ; 
single pair of cauline leaves on 
the lower half of the short stem 
upper involucral 
leaves much broader at base ; ca- 
lyx about 1 inch and corolle 1} 
inches long ; lobes of corolla deep 
azure Wes about 1 inch long, 3 
lines wide ; tube inside greenish 
yellow, with short purplish-brown 
filaments ; lower part of the fila- 
ments attached in the middle, the 
free edges beset with long and 
slender fringes; oblong glands 
ween the bases of the fila- 
ments very marked ; seeds (un- 
ripe) very similar to those of the 
allied G. crinita, rough from 
scales, which properly are desic- 
cated vesicles, protruding epider- 
mis-cells. Our species is in many 
respects the American representa- 
tive of the European G. ciliata ; 
both are perennials with short 
peduncles, with ciliated bases of 
the filaments and short oval ova- 
ries, but the seeds are very dif- 
ferent.?
