A. 1. C. 2. Lat. 50-51°. Alt. 0- ? yds. Tem. 51°. 



Stems diffused^ rooting at the base (there is occasionally an erect 

 central stem, but the lateral spreading and rooting stems distin- 

 guish this plant from O. sti^icta) . Leaflets deeply notched, with 

 a stipule adherent to the petiole. Pedicels reflected when bearing 

 the fr'uit. Peduncles about as long as the leaves. Fruit invested

 nists to these plants.
