NELson: NEW PLANTS FROM WyYoMING © 245 
The best example I have seen of G. monantha is Dr. Clements’ 
no. $50, Mirror Lake (altitude 3500 m.), Colorado, Sept. 6, 1901 ; 
I name this as the type. 
Chondrophylla gen. nov. 
Small biennials (?) from a few cm. to 1 dm. high, the stems 
single or several from the slender root. Leaves numerous, small, 
opposite, seemingly imbricated below because of the short inter- 
nodes, the margins white and scarious or cartilaginous. Flowers 
solitary and deriainut Calyx narrow, 4- or 5-toothed. Corolla 
salver-form when expanded, plicate at the sinuses with broad 
emarginate lobes or plates, without crown or glands. Anthers 
cordate, versatile. Seeds oblong, with a close coat. 
The two species following, which have long stood as a section 
of Gentiana, are so completely out of harmony with the other 
sections of that genus that it would certainly tend toward sim- 
plicity to elevate the section to generic rank. In doing so I have 
used the sectional name of Bunge and Grisebach. The minute 
cartilage-margined leaves, the solitary terminal flowers, the versa- 
tile anthers are generic characters separating these plants from 
Gentiana. 
“ Chondrophylla Fremontii (Torr.) 
Gentiana humilis of Gray, Syn. Fl. 2': 120; Engelm. Trans. 
Acad. St. Louis, 2: 217, pi. 9; G. Fremontii Torr, in Frém. Rep. 
94; probably G. humilis Stev. Act. Mosq. 3: 258. 1812; Griseb. 
Gent. 251: not G. humilis Salisb. Prodr. 137. 1796. 
Since the specific name so long in use is not available, I take 
up Torrey’s name. 
“Chondrophylla Americana (Engelm.) 
Gentiana prostrata Americana Engelm. Trans. Acad. St. Louis, 
2: 217, pl. 9, 1862; probably not Gentiana prostrata Haenke ; 
Jacq. Coll. 2: 66, nor of later authors. 
The Rocky Mountain plant seems to be distinguishable from 
the arctic and European forms, so Engelmann’s name is adopted. 
’ Hedeoma ovata sp. nov. 
Perennial, the slender branches of the caudex widely divaricate 
from the summit of the taproot ; stems slender, branched, 12-20 
cm. high, puberulent with recurved hairs: leaves entire, oval, from
