GILIA FAMILY 193 



Gilia gUmanii is somewhat allied to G. latifolia. Gilia gilmanii is a woody-based perennial, 

 the flowers with 4 short stamens and 1 long stamen which are inserted near base of corolla-tube 

 and included in the tube. Gilia latifolia is an annual, the flowers with 3 short and 2 long stamens 

 which are inserted near middle of corolla-tube and exserted from the throat. The leaf-blades of 

 Gilia gUmanii are coarsely spiny-dentate ; those of Gilia latifolia are spiny-dentate with the lower 

 ones frequently pinnately divided.

 disappears early) ; herbage minutely puberulent, the stems sometimes a little glan- 

 dular; leaves 14 to 1^4 inches long, the blades pinnatifid with 3 to 7 cuspidulate 

 segments, narrowed gradually to a winged or un winged petiole; flowers in close or 

 head-like terminal clusters, the clusters very leafy-bracteate, % to % inch broad ;

 than the basal ; flowers cymose, the filiform pedicels 1 to 4 lines long, solitary, or 

 the flowers clustered in small glomerules; calyx parted nearly to base, the lobes
