MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 208 
11. Drymocallis reflexa (Greene). 
Potentilla glandulosa var. refleca Greene, Fl. Fran. 1: 65. 1891. 
Potentilla refleca Greene, Pittonia, 8: 19. 1896. 
Rydberg, Bull. Torr. Bot. Club, 23: 247. 
IntustRATIONS: Puare 110, f. 1; dissection of flower, f. 2; petal, f. 3; pistil, f 4; 
stamen, f. 5; fruiting hypanthium and calyx, f. 6. 
Stems generally several from the caudex, slender, branched, more or less tinged with 
purple, 8-4 dm. high, minutely villous. Stipules lanceolate to ovate, entire or toothed. 
Basal leaves many, rather short-petioled, finely silky-hirsute, rather firm in texture, pin- 
nate; leaflets about 4 pairs, 1-3 em. long, broadly oval or obovate, coarsely serrate with 
broad teeth, sometimes somewhat incised. Stem leaves 5-foliolate or ternate, more acute. 
Cyme open, with rather long slender branches. Flowers about 1 em. in diameter. Hy- 
panthium rather densely short viscid-villous, in fruit 10 mm. in diameter; bractlets 
ovate-lanceolate, scarcely half as long as the ovate or ovate-lanceolate acute or mu- 
cronate sepals. Petals dark yellow, obovate, scarcely equalling the sepals, both reflexed 
in anthesis. Stamens about 25; filaments short; anthers deeply cordate at the base. 
This somewhat resembles D. glandulosa. The principal difference given by Professor 
Greene is that petals and sepals are reflexed in anthesis. As far as I know the species, 
the following characters may be added: thicker, darker leaves with broader and shorter 
teeth, a more slender stem which is inclined to be tinged with red, and a fruiting hy- 
panthium scarcely larger than that of the next species. According to Professor Greene, 
it is common in dry open pine woods of the foothills of the Sierra Nevada. I have 
seen specimens from the following collections :
