CALIFORNIA ACADEMY OF SCIENCES. 69 



Mountains of the peninsula of Lower California, collected 

 by Mr. C. R. Orcutt, July, 1884. 



A very freely branching species with the habit of E. mi- 

 mdiftora, but more nearly allied to E. Calif arnica. 



•s-+ ++ Torus without conspicuous rim. 



E. Mexicana. 



Annual, smooth and glaucous : foliage less finely dissec- 

 ted: stems short: peduncles numerous, stout and scape-like: 

 petals an inch long, yellow or cream color: torus short, ob- 

 conical, the outer margin a sub-cartilaginous ring, the inner 

 erect, scarious, with stout nerves: seed globular apiculate, 

 with coarse but rather faint reticulations. — E California i, 

 var. parvula. Gray. PI. Wright, 2. 10. E. Douglasii, 

 Torr. Mex. Bound, 31; Heinsl. Biol. Cent. Am. 



This plant ranges from the region of the upper Gila, in 

 New Mexico, far southward into Texas and adjacent Mexico, 

 and is apparently a very good species. 



E. Austinae. 



Perennial: stems slender, erect and branching, hirsute 

 below, only sparingly scabrous, or sometimes quite smooth 

 above: segments of the leaves slender and remote: petals 

 yellow, an inch long: torus almost cylindrical, only a little 

 widened above, the outer margin a faint, herbaceous ring, 

 the inner deeper and hyaline: seeds with conspicuous but 

 irregular reticulations. 



Collected in Butte County, 1883, by Mrs. R. M. Austin; 

 also in the same year, further down the Sacramento Valley, 

 near Elmira, by Mrs. Curran. Doubtless a common species 

 of the region, and one which, in the collections, would nat- 

 urally be put in with E. Californica by those who disregard 

 the importance of the character of the torus. 



I gladly dedicate the species to one of the most intelligent 

 and helpful of our field students of California botany.
