2. ECHINOSPERMUM FLORIBUNDUM, Lehm. 



Echinospermum floribundum, Lehm. Pug. 2, p. 24 ; Hook. Fl. Bor.-Ain. 2, p. 54, 

 t. 164 ; DC. Prodr. 10, p. 143. 



Hab. Upper Columbia, Washington Territory; in various places. — 

 This is placed among the doubtful species of Echinospermum by De 

 Candolle, who appears to have overlooked the full description and 

 excellent figure of Hooker, 1. c. It seems to be most nearly related 

 to E. brachycentrum of Ledebour. The nutlets are somewhat hetero- 

 morphous ; two opposite ones having a wider margin than the other 

 two. Our plant is the same as No. 633 of Fendler's New Mexican 

 collection.

1. Hydrophyllum Virginicum, Linn.

 eastern plant only in the smaller flowers, and in the filaments being 

 much less hairy near the middle. 



2. Hydrophyllum capitatum, Dougl. 



Hab. Spipen River, Washington Territory ; in moist places.— The 

 root consists of long thick fasciculate fibres which abound in starch.
