 deeply serrated or incised leaflets, which are cottony and white 

 on the under side, and dark green on the upper side ; stipules 

 lanceolate, tapering. Flowers in terminal, downy "corymbs. 

 Calyx white, like the under side of the leaflets. Corolla small.

Stems very woody, short, prostrate. Leaves ternate, petiolate ; 

 leaflets obovate or obcuneate, with a 3-toothed apex. Flowers 

 bracteate, on short, stout, hairy stalks. Sepals triangular or 

 lanceolate, hairy. Petals very small and fugacious, obovate, 

 linear, greenish-yellow. Stamens few. 



Ben Lawers, and other alpine heights, on rocky spots. Per- 

 ennial; July. 



P. recta. Erect Cinguefoil, Fl. Dan. 11, 1820. — Stem quite

 cessary divisions of the genera existing ; but it would be desirable that botanists 

 of more influence than the writer of these descriptions should propose their discon- 

 tinuance.
