M. Sibirica Howell 1. c, 38. Claytonia Sibirica L. Sp. 204(?), Sca- 
pose stems 6-15 inches high from a thickened crown with fibrous roots: 
radical leaves rhombic-ovate or nearly orbicular to lanceolate, 1-3 inches 
long, 4-2 inches wide: involucral leaves ovate or spatulate-ovate to lan- 
ceolate, 4-2 inches Jong: flowers on slender pedicels in elongated bracted 
geminate racemes ; sepals ovate, acute, 1-1‘ lines long; petals oblong, nar- 
rowed to a short claw below, somewhat truncate and notched at the upper

of the Cascade Mountains. 
M. bulbifera Howelll.c. Claytonia bulbifera Gray 1. ¢. ati, 54. Stems 
rather slender, 4-12 inches high, erect or ascending from a cluster of 
bulblets that are the fleshy persistent bases of former leaves: leaves orbic- 
ular or rhombic to lanceolate, 6-18 lines long, narrowed below to a slender 
petiole 2-4 inches long: involucral leaves orbicular to oboyate or elliptical, 
sessile but not connate: raceme solitary and terminal, rarely with a second 
one in the axil of a bract below the terminal one; bracts foliaceous ; pedi- 
cels filiform, 1-2 inches long: sepals cordate, 1-2 lines long, about as 
broad, acutish; petals oblong, emarginate to 2-lobed, 4-6 lines long, white 
with red or purple veins; stamens about half as long as the petals: cap- 
sule globose: seeds moderately compressed, ovate, with a conspicuous 
white appendage at the hilum. Along streams and damp places in forests, 
southwestern Oregon and adjacent California. 
§$ IV. Sepals 2, broad, more or less scarious, persistent: cap- 
sule 2-valved. . 
9. SPRAGUEA Torr. Pl. Frem.4t. 1. 
Herbs with rosulate tufts of fleshy leaves from the crown of 
a fleshy root, 6dr on densely-leafy stems, and ephemeral flowers in 
dense scorpioid spikes umbellate-clustered on a scape-like pedune- 
le. Sepals 2, orbicular, emarginate at both ends, scarious-hyaline, 
persistent. Petals 4, somewhat unequal. Stamens 3, opposite 
the 3 larger petals, exserted. Ovary 8-10-ovuled; style long, bifid 
at the apex. Capsule 2-valved, membranaceous. Seeds black 
and shining. 
S. umbellata.Torr. 1. c. Stems several from a thickened biennial 
root, simple, erect or ascending 2-12 inches high: radical leaves spatulate 
or oblanceolate, on thick petioles 1-4 inches long; the cauline similar but 
smaller, frequently scarious-stipulate, often reduced to a few bracts; invo- 
luere of broader scarious bracts subtending the dense capitate umbel of 
nearly sessile spikes: sepals very conspicuous, 2-4 lines in diameter, about 
equailing the oblong-ovate petals: stamens and style conspicuously ex- 
serted. In damp sandy places from the Siskiyou to the Sierra Nevada 
Mountains. 
S. multiceps Howell Eryth. i, 39. Depressed freely branching per- 
ennial: stems 1-6 inches long with densely leafy branches: leaves 3-6 
lines long or on young plants 2 or 3 inches long: peduncle solitary, 
terminating the short lateral bractlets, usuaily with 1 or 2 scarious bracts 
below the involucre: flowers in dense capitate clusters: sepals scarious, 2-4 
lines in diameter, about equalling the oblong-ovate petals: stamens and 
style conspicuously exserted. In yoleanic sand, etc., on the snowy peaks 
of the Cascade Mountains.
