ZAUSCHNERIA California, Presl. in Torr. and Gr. Fl. Am vol. i. p. 486. 



Banks of Deer Creek. August. I have under my eyes three very distinct forms 

 of Zauschneria ; one, (var. a.) pubescent, narrow-leaved, with bright red calyces and 

 corollas. The second, (var. p.) Mr. Pratten's plant, is villous-canescent, with broad-oval 

 leaves; calyces of a fulvous color, longitudinally veined, and tips of petals brightly red. 

 The third form, which might prove a distinct species, is also villous-canescent, 

 with ovate-lanceolate acute leaves, repandly denticulate, and very much like the 

 Moral leaves of OEuothera biennis ; calyx and corolla of a uniform bright scarlet 

 color; flowers large, bracteate, on a long terminal spike. The latter was collected 

 by Dr. Heermann at Posa Creek, South California. 



OENOTHERA (GODETIA) biloba, Sp. Nov. Caulis adscendens, ramosus, sub- 

 glaber, ramis virgatis ; foliis lineari-lanceolatis, denticulato-repandis, basi attenuatis, 

 petiolatis; fioribus sessilibus purpureis ; calycis tubo infundibuliformi ; petalis an- 

 guste cuneatis, obcordato-bilobis, staminibus multo longioribus; antheris longis, 

 reflexis ; pistillo stamina valde superanti ; stigmatibus purpureis, quadrifidis, lobis bre- 

 vibus, subovatis; germine lineari, acuminato, pubescenti. 



OS. biloba and OE. (Jecumbens are, I believe, the only species of section Godetia. having 

 deeply bilobed petals. The flowers are moderately large, lilac color, and showy. The 

 stamina are much shorter than the style, stigma purple, germ linear-acuminate and 

 sessile. I have not seen the ripe capsules.
