CHORIZANTHE. 59 



19. C. STATicoiDES, Bcnth., Watson, 1. c, including C. Wheeleri, 

 Watson. Usually strict, with naked stems, sparingly branched above, 

 or horizontally spreading near the base, 3-12 inches high, pubescent 

 with appressed hairs, greenish when young, reddish-purple when mature, 

 terminal cymes rather condensed; radical leaves oblanceolate, taper- 

 ing to a longer or shorter petiole; tomentose beneath, cauline bracts 

 acicular; involucres cylindric, with more or less prominent ribs; divis- 

 ions unequal, short recurved, and uncinate awned, the lower axillary 

 ones usually much larger; flowers nearly sessile; perianth segments 

 partly exsert, Yi cleft, narrowly ovate, with broad claw, internal shorter 

 and narrower; stamens 9, rarely reduced to 6, anthers oblong; styles 

 akene and embryo, as in other allied species. 



Habitat: Dry plains- throughout Southern California; the low 

 branching forms near the coast; one of the most variable species, to 

 include C. Wheeleri^ Watson, which, judging from an original speci- 

 men kindly furnished by Dr. J. T. Rothrock, is only a depauperate 

 coast form, with stamens reduced to 6, which is not uncommon in the 

 succeeding species. 



20. C. Xanti, Watson, 1. c. Branching from or near the base, 

 2-12 inches high, hoary or tloccose pubescent; radical leaves spath- 

 ulale, abruptly tapering into a winged petiole, tomentose beneath, 

 lower cauUne bracts foliaceous, gradually passing above into setaceous; 

 involucres scattered in the lower axils, in loose cymose clusters above, 

 tube narrow-cylindric, densely tomentose externally, ribs more or less 

 prominent, divisions somewhat unequal, shortly curved, and uncinate ; 

 flowers nearly sessile, with narrow tube; perianth segments partly 

 exsert, yi cleft, oblong, entire, the inner one half shorter; stamens 6-9 

 unequally developed, anthers oval; styles and akene similar to the 

 above; embryo nearly 2 lines long, with hnear cotyledons, and slender 

 radicle. 



Habitat: San Gorgonio Pass; Parry and Lemmon, 1876. A low, 

 slender form, with 6 stamens; copiously collected June, 1883, on Te- 

 hachipi Pass, more robust, with uniformly 9 stamens. Some interme- 

 diate forms from Los Angeles, Rev. J. C. Nevin, seem to connect this 

 species with the preceding {C. staticoides). 



* * * Decumbent, branching from the base, diffusely and dichotomously 

 spreading above; involucres scattered, or more or less cymosely clustered; divisions 

 unequal, variously margined and awned; perianth segments nearly equal, or con- 

 spicuously unequal; stamens 9, rarely 3; cauline bracts foliaceous or setaceous.
