278 HYDKOPHTDLACEAE 



strigose, 1 to 3 inches long; petioles V2 to 8 inches long; racemes loose; fruiting 

 pedicels spreading or horizontal, ^4 to 1 inch long ; calyx-lobes linear, glandular- 

 hispid and -puberulent; corolla deep blue, funnelform-campanulate (the tube 

 ■widened upward, not at all ventricose), % to lYz inches long, the limb % to II/2 

 inches broad ; corolla-lobes twice as broad as long ; stamens exserted, the filaments 

 with a quadratish dilation at base, the dilation glabrous or sometimes hairy. 



Sandy desert washes, rocky outcroppings or stream beds in valleys, 1600 to 

 4500 feet : Mohave and Colorado deserts. Mar.-May. The herbage stains paper 

 and is a skin irritant.
