suborbicular in outline, 2-2.5 cm. in diameter, cleft into seven cre- 
nately toothed crenate lobes, cordate, slightly pubescent on both 
surfaces, on petioles about equalling the blade; scapes (appearing 
in late summer or fall) usually two or four together, rarely solitary, 
erect, 4-25 cm. tall, simple or branched above; flowers few in a 
terminal cyme or cymose panicle ; calyx campanulate with a trun- 
cate base, 4-6 mm. high, marked with ten brown branching nerves, 
its five triangular obtuse teeth about one-half as long as the tube; 
petals white with brownish or purple nerves, elliptic-obiong or 
elliptic-lanceolate, sometimes nearly ovate, 4-6 mm. long, about as 
long as the calyx, obtuse ; stamens ten, the alternate ones longer, 
inserted on the calyx-tube above the middle (below the petals); 
filaments slender, subulate ; follicles 7-9 mm. long, united at the 
base, the body nearly included in the calyx, the slender tips sur- 
passing the calyx and diverging at right angles; seeds small, dull- 
brown, I mm. jong, irregularly oblong, provided with two ribs and 
two crests. (Plate 256, copied from Bot. Mex. Bound. Survey.) 
Original locality, « Dry Hills near San Diego and San Luis 
Rey, California.” Found later near San Diego (Orcutt, 1885); 
lone, Amador County (Parry, 1887). Flowering in November 
and December. 
2, JEPSONIA MALVAEFOLIA (Greene). 
Saxifraga malvaefolia Greene, Bull. Torr. Club, 19: 121. 1882. 
Original locality, « Santa Rosa Island.” Found later on Santa 
Cruz Island, 
These two remarkable plants form a very distinct and natural 
§enus, They are strikingly different from any species of Sazi- 
Sraga in habit and the flower affords good characters. The calyx 
'S simply toothed instead of cleft or parted, the petals and stamens 
are inserted in the upper part of the calyx-tube and not down 
where the ovary and calyx meet. The ovary fills but a small part 
_Of the calyx-tube and its stigmas are peltate and conspicuous, Op- 
Posed to the capitate and inconspicuous ones in Saaifraga, the y 
seed with its pinched and twisted base, its ribs and crests, has oe :
