RANUNCULUS, RANUNCULACE. 15 
bage light green, glabrous or nearly so, leaves all entire, obtuse, radical 
ones oblanceolate, long-petioled, 2-4 inches long; cauline lanceolate to 
_obovoid or oval, the upper ones with very short dilated and thin sheath- 
like petioles: sepals roundish, spreading, thin: petals 5-8, broadly obovate, 
2-3 lines long, golden yellow: achenes obovate, moderately compressed, 
obscurely margined, obliquely tipped with a short style. Very common in 
wet places in the Willamette valley, and from W. Washington to the Sier- 
ra Nevada Mountains in California, 
R. Gormani Greene Pitt. iii, 91. Stems several, from a fascicle of per- 
ennial, thick but slenderly tapering fleshy-fibrous roots, simple, prostrate 
at base, rooting and bearing leaves at 2-3 nodes, the terminal part naked, 
ascending and scapiform, bearing a solitary small flower: leaves broadly 
ovate or deltoid-ovate, acute, coarsely few-toothed, 6-9 lines long, glabrous, 
on almost filiform somewhat pilose-hairy petioles 1-3 inches long: petals 5, 
oblong, obtuse, twice the length of the spreading sepals: achenes small, 
glabrous, moderately compressed, with a slender curved beak as long as 
the body. Collected by Mr. M. W. Gorman on wet banks at Cathedral 
Springs, Crater Lake, southern Oregon, Aug. 22nd, 1896. 
R. alismellus Greene Fl. Fr. 297. R. alismefolius var. alismellus Gray. 
Glabrous ; stems slender 2-12 inches long: radical leaves ovate or elliptical 
to oblong or cordate, 6-15 lines long, on long slender petioles; cauline 1-2 
or none, narrower, subsessile: flowers solitary, 4-7 lines broad, on long 
slender peduncles: achenes few, the mature ones unknown. In wet mead- 
ows on the highest mountains, Washington to California.

new series +. 615. Stem solitary, from a fascicle of fibrous roots, erect, 
leafy, the whole plant flaccid and glabrous, 6-10 imches high: leaves thin- 
membranaceous, from round-reniform to cordate-ovate, obtuse, entire or 
obscurely crenate, long petioled; the cauline smaller, ovateand ovate-lanceo- 
late, sessile: peduncles many, slender, longer than the cauline leaves to 
which they are axillary: flowers yellow, 4 lines broad: petals 5-6, obovate- 
‘oblong: heads of rather numerous thick short-pointed achenes small, glo- 
bose or depressed-globuse. Mountains of eastern Oregon and Idaho. 
R. Bolanderi Greene, Bull. Calif. Acad. ii, 58. Glabrous throughout 
or the peduncles and calyx pubescent: stem stout, erect, 1-3 feet high: 
leaves lanceolate, sparingly callous-denticulate, obtuse, the lower ones with 
blade 4-6 inches long on petioles 5-12 inches long, the cauline ones few 
nd short-petioled or subsessile ; petals broadly obovate 3-5 lines long, twice 
as long as the rounded spreading sepals; scales minute: achenes smooth, 
moderately compressed, pointed with a slender beak, crowded in a com- 
pact ovoid head. In wet places, Willamette valley to northern California. _ 
* * * Terrestrial species with at least some lobed or divided leaves, 
and no stoloniferous rooting or creeping stems except in R. repens. 
+ Radical leaves few, only lobed: achenes turgid and dorsally roun- 
ded, in a globose head. 
R. glaberrimus Hook. Fl. i, 12, t.5, Fig. A. Glabrous: stems weak, 
2-6 inches long, erect or decumbent: leaves all petioled, radical broadly 
oval, rounded and coarsely toothed or lobed at the apex; cauline subcu- 
neate, trifid or entire:. petals 5, obovoid, 4-6 lines long, twice the length 
of the oval spreading sepals: achenes plump, puberulent, slender-beaked, 
in large globose heads. In wet places, eastern Washington and north- 
ward: flowering in very early spring. 
R. ellipticus Greene Pitt. ii, 110. Very glabrous: stems several, 2-3 
inches high, from a large fascicle of perennial fleshy-fibrous roots: radical 
leaves elliptical, entire, acutish at both ends, the petiole equaling the blade; 
the cauline narrower, often cleft into 2-3 linear divisions: petals often wan- 
ting, sometimes 1 only, or 5, large, broudly obovate or more rounded, bright
