Phacelia argentea, n. sp. — Differs from P. magellanica (Lam.) 

 Coville, in the broad suborbicular or broadly oval densely serice- 

 ous leaves (2-4 cm. long, 2-3.5 cm. broad). Although evidently 

 nearest related to P. magellanica as understood by Brand in his 

 discriminating monograph, P. argentea is of unique aspect, entirely 

 different from any of the plants referable to this group. The stems 

 and petioles are hispid or hirsute, but the leaf blades are clothed 

 with an appressed (less so beneath) satiny pubescence. 



The specimen is imperfect, but the plant is probably robust and tall. 

 Even though only vegetative characters are available for discrimination, there 

 is no evidence that these intergrade, so the plant is proposed as a new species.

 Herb.). 



GILIA and COLLOMIA.— Although Brand in his recent 

 monograph of the Polemoniaceae maintains Collomia as a genus 

 distinct from Gilia, it is surely no better marked than some other 

 sections raised to generic rank by many American botanists. 

 " Calyx not ruptured by the maturing capsule" is a good enough 

 (and the only constant) sectional character, but scarcely to be 

 considered generically in a family in which the more natural genera 

 run hopelessly together technically. And when all the Collomia 

 species are taken into account, they present no common aspect 

 that might tempt one to treat them as a genus, a characteristic 

 which some of the other sections possess. In accord with this view 

 we are making two necessary transfers. 



Gilia mazama (Coville), n. comb. — Collomia mazama Coville, 

 Proc. Biol. Soc. Wash. 11:35. 1897. 



Gilia tenella (Gray), n. comb. — Collomia tenella Gray, Proc. 

 Am. Acad. 8:259. 1870. — The range given in the Coulter and 

 Nelson Manual would be more nearly correct, if it read "Moun- 

 tains of southern Idaho to Oregon and Utah." 



Gilia achilleefolia Benth. var. Chamissonis (Greene), n. 

 comb. — G. Chamissonis Greene, Erythea 3:105. 1895; subsp. 

 Chamissonis (Greene) Brand, Pflanzenreich 4, fam. 250. in. 

 1907. — Mostly, if not entirely, replaces in the Northwest the typical 

 form with permanently arachnoid-villous calyx. Both grow in 

 California.
