II. Drymocallis reflexa (Greene). 



PotentiUa glandulosa \ar. reflexa Greene, Fl. Fran. 1: 65. 1891. 



Potentilla rcflcm. Greene, Fittonia, 3 : 19. 1896.

Stems generally several from the caudex, slender, branched, more or less tinged with 

 purple, 3-4 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 cm. 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 cm. 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. glanduJosa. 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 :
