GiLTA INCISA, Benth. I. c. p. 312. Central and western Texas to the Eio Grande, also in New 

 Mexico, Chihuahua, and Neuvo Leon. Plant 12-18 inches high. It appears to be both 

 annual and biennial. Flowers white. The radical leaves often form a cluster, and are much 

 less cut than the stem leaves. 



GiLiA RiGiDULA, Benth. L c. Hill sides and rocky ravines, western Texas, New Mexico, and 

 Sonora, March — May. (No, 1645, Wright.) Perennial. Plant 4-10 inches high, branching 

 from the base, viscidly pubescent or almost glabrous. Leaves mostly simply pinnatifid, with 

 5-7 distant rigid and pungent segments, which vary from oblong-lanceolate to very narrowly 

 linear. The flowers are nearly three-fourths of an inch in diameter. Corolla bright blue, 

 yellow in the throat. Cells of the ovary with several ovules.
