40 ERYTHEA. 
emarginate anthers, delicately rugulose: style very distinctly 
hispidulous almost throughout: capsule not exceeding the 
calyx, valvate from the very apex. 
Common in the higher Sierra Nevada of California. The 
flowers appear to be constantly tetramerous; but there are 
no gradations whatsoever between this and D. alpinum of the 
same general range. 
D. tetrandrum, Suksdorf in herb. Root characters and 
general aspect of the last, but leaves ampler, relatively 
broader; the whole plant glabrous, or else the calyx with a 
trace of the puberulent under a lens: corolla purplish, with 
a yellow ring near the base, the segments, and also the 
stamens usually 4 only (occasionally 5): connective slender- 
subulate from a short deltoid base, obscurely rugulose below: 
style glabrous: capsule surpassing the calyx, circumscissile 
very near the apex. 
Mountains apparently throughout eastern Washington and 
Oregon; collected by Suksdorf, Cusick, and, on Drew’s 
Creek in southeastern Oregon, by Mrs. R. M. Austin. Quite 
distinct from D. Jeffreyi, though it is the nearest ally of that 
species; but it belongs to another tract of country. 
D. conjugens. Short crown with a dense fascicle of 
fleshy-fibrous roots that are deciduous from it after the flower- 
ing: whole plant glabrous: leaves obovoid and elliptic, 2 to 
5 inches long including the distinct petiole, obtuse, entire: 
scape stoutish, 3 to 8 inches high: umbel few-flowered; 
flowers large, 5-merous, rarely 6-merous: corolla deep pur- 
ple, varying to rose-red and to white: anthers distinct, 
obtuse, the connective lanceolate, acuminate to a linear point, 
delicately rugulose throughout all but the linear tip: fruit 
unknown. 
Species remarkable as forming a link between D. Hender- 
sonii, of which has the root and leaf characters, and that 
boreal and alpine group which have their anthers distinct. 
My first specimens were from Prof. Kelsey, who obtained 
them on dry hills near Helena, Montana. Better material is 
now in hand collected in southeastern Oregon, in 1893, 
by Mrs. R. M. Austin.
