Hab. North -West coast of America. Mr. Menzies. In shady pine woods, among moss; common near 

 the shores of the Pacific, about the mouth of the Columbia. Douglas. Scouler. Forfe Vancouver. {Mr. 

 Garry.) — What De CandoUe took for petals, in examining this plant, in Sir James E. Smith's Herbarium, I 

 presume must have been stamens, from v\ hich the anthers had fallen ; for, after the strictest examination, 

 both of young and more advanced flowers, I can find no trace of a 6oral covering. Sir James E. Smith showed 

 much judgment in referring this plant to Leontice^ from which it scarcely ditfers in the flowers, except in 

 there being no floral covering. The structure of the anthers is the same in the two, and hence I have 

 removed it from the Podophylle<B of De Cand. to the Berberide<B, whose stamens have their anthers opening 

 by means of valves, Jeffersonia, too, placed by De CandoUe in Podophyllem, has equally the cells of the 

 anthers valvular.
