 ish-cordate, crenately 5-7-lobed ; flowers at first crowded, at length an open 

 raceme ; petals inconspicuous, short-lived ; seeds roughened (under lens). Fre- 

 quent on rocky banks.

6. FENDLERA (Named for Augustus Fendlbr) 



An erect pubescent shrub with entire leaves ; calyx tube 8-nerved ; petals 

 clawed, emarginate at apex ; filaments 2-forked at apex, the lobes surpassing the
