lineari-oblonga in stipitem brevem attenuata. 
Mount Flora and other alpine peaks of the Snowy Range, Colorado, Parry, No. 306; Hall & Harbour, No. 
475; Russian Arctic America, Chamisso in Herb. Gray. — A very small form, 1-2} inches high, single or with a few 
ascending or prostrate branches from 
the base; flowers always 4-parted 
(in the European plant, which I 
have been unable to compare, they 
are said to be 5-parted), deep azure 
blue, 53-6 lines long, scarcely 1 line 
in diameter; capsule tapering at base, 
not abruptly rounded; seeds finely 
striulate, 4 line long 
‘y Fig. 10, 3 specimens of 
the smaller form, nat. size: 11, a 
flower ; 12, corolla, laid open; 13, 
pistil ; 14, capsule, Regence mag- 
ified ; 15, seeds, 10 times magni-

Parry, No.135; Hall & Harbour, No,

Fremont ; flowers June and July. — 
Many erect or ascending, rarely pros- 
trate, one-flowered, fragile, succulent 
stems, 1-5 inches high; pale green 
leaves, with a broad white margin, 
cuspidate or mucronate, — lower ones 
orbicular or ovate, rosulate, — cau- 
line ones linear-oblong, connate at 
base and sheathing ; flowers on short 
or longer peduncles, 4-43 lines long, 
parent folds ; ovary lance-oval on a 
short stipe, style short with recurved 
stigmas; capsule on a stipe of dif- 
ferent length, usually raised above 
the corolla, but sometimes enclosed 
in it, and then, at last, bursting side- 
ways through the integuments, as 
appears on the left-hand branch of 
our figure ; valves of capsule at last 
widely opening, as the figure shows, 
and giving the plant a very singular 
Puate IX. — 1-5, G. numius. 6-9, G, ACUTA, VAR. 10-15, G. PROSTRATA, VAR. 
appearance ; seeds irregularly linear-oblong, nearly } line long, finely striulate, very similar to those of the last 
species. 
Specimens from the Altai Mountains are absolutely identical with ours with the exception of the folds of [218] 
the corolla, which in the former have acute and in ours obtuse lobes. PI. 9, Fig. 1-5.
