shortly petioled, broadly oval (the later ones oblong) acutish, 
narrowed into the petiole, entire, veined, the blade a half inch

ovate, obtuse. Petals three times longer than the calyx, bifid; 
the lobes obtuse. 
’" —_ SAXIFRAGA 'MERTENSIANA 141. Scape subnude, leaves 
subrotund incised-lobed, lobes somewhat three toothed, pedun- 
cles glandular pubescent, sepals ovate acutish, petals ovate acute 
very shortly unguiculate three nerved. 
Radical leaves suborbicular, incised lobed; segments sub- 
tridentate; glabrate, sparingly provided with white hairs, base 
cordate, and decurrent into the cuneate petiole, 14-2 inches 
long and broad. Petioles elongated, 3-4 inches, sparingly pu- 
bescent with white hairs. Scape ascending, erect, simple, sub- 
nude, provided with a single leaf near the base, terete, pubescent 
with short white hairs, about a foot high. Flowers paniculate; 
branches alternate, and with the filiform pedicels glandular pu- 
bescent. Bracts lanceolate, minute. Calyx scarcely gamosepal- 
ous at the base; sepals oblong, acutish, reflexed. Petals sub- 
equal, ovate, acutish, attenuate at base into a claw, entire, triple 
nerved; lateral nerves diverging from the middle a little above 
the base; twice longer than the sepals, bilinearia, a line and less 
narrower. Stamens 10, about equalling the petals; filaments 
clavate, the apex acute. Anthers ininute, subglobose. Ovary 
ovate, as long as the style. 
It differs from S. punctata to which it is related: 
1 By its taller growth; 2 the lobes of the leaves tridentate 
or crenate (not entire); 3 petals acute, three nerved (not obtuse, 
one nerved).
