SOME SPECIES OF DODECATHEON. 39 
crenation of the leaf-margin fails; and that is, a certain very 
pronounced callous point which exists in every sinus of the 
crenate-leaved state, which callosity I find besetting, like a 
regular denticulation, the whole margin of the leaf in certain 
forms, which, at first glance appears to differ from those of 
D. viviparum in being entire. Rhizomatous plants with just 
this callous-denticulate (but not crenate) leaf margin I have 
from western Montana, collected by Professor Kelsey. 
D. alpinum. D. Meadia var. alpinum, A. Gray, Bot. 
Calif. i. 467. Plant wholly glabrous, slender, from a few 
inches to a foot high: leaves not excessively numerous, 
usually spreading or depressed, small (mostly about 2 inches 
long), from oblanceolate to nearly linear, entire, acutish: 
flowers few, large, 4-merous, deep red-purple: stamens 
slightly if at all united at base; connective of anthers 
slender-subulate from a broad base, visibly co-extensive with 
the anther and plicate-rugulose: capsule valvate from the 
apex. 
Common along boggy margins of subalpine lakes in the 
Sierra Nevada of California, more especially from Donner 
Lake southward. It is the D. Jeffreyi of Coville, Bot. 
Death Val. Exp. 147, but wholly distinct from that large 
species. Many specimens, doubtless young in years, show 
neither distinct rhizome nor bulblets.

D. Jerrreyi, Moore, in Fl. des Serres, xvi. 99 (1867). 
D. Meadia var. lancifolium, A. Gray, Bot. Calif. i. 467 
(1876). Plant with inconspicuous crown, and abundant 
fleshy-fibrous persistent roots: leaves oblanceolate, erect, 
5 to 10 inches long, entire, acutish, mucronate: scape 1 to 14 
feet high; umbel many-flowered, the pedicels and calyx 
hirsute and glandular, even the outside of the corolla sparsely 
pubescent: segments of the corolla ample, deep red-purple: 
stamens distinct, dark purple, the connective slenderly subu- 
late from an ovate base, reaching to near the tips of the
