 apiculAtdsi, Greene (Fl. Francis. 304, D. apiculalum, Greene, Pittonia, i. 285), of tlm

 numerous flowers and somewhat broader leaf-segments. 

 +- -J— Roots grumous or fjiscicnlate-tuborous, i. e. thickening into globular or oblong or often 



palmate tubercles (of annual or biennial duration), bearing only fibrous rootlets: flowers 



mostly blue or violet. 

 ++ Raceme spiciform and virgate, mostly many-flowered : pedicels shorter than the spur, 



erect or even appressed both in flower and fruit : stem strict, mostly several-leaved, simple, 



or the larger plants bearing one or more smaller lateral racemes. 

 D- simplex, Dougl. Tall, about a yard high, pubescent throughout with short and soft 

 spreading almost velvety down : leaves all dissected into linear divisions and lobes ; caly.x

 erect, and with approximate or little spreading linear divisions and lobes: flowers usuallv 

 approximate in tiie very spiciform raceme, then conspicuously distidions: sejtals at first

 much less colored : follicles seldom over half inch long, erect. — Geyer in Hook. Lond. Jour.
