Eefs. — Eriogon'UM marifolium T. & 6. Proc. Am. Acad. 8: 161 (1870), based on Lobb

 204, lilamcnts glabrous; Merriam, N. Am. Fauna, 16: 143 (1899). 



64. E. kelloggii Gray. Pedxiiieles rising from a loose mat, seape-like, 

 slender, 2 to 4 inches high, naked save for whorl of 3 leaf-like hraets at the 

 middle; mat consisting of branching stolon-like woody stems with the leaves 

 in rosettes on the ends of short branchlets; herbage tomentulose throughout 

 or the leaves glabrate above; leaves oblanceolate or narrowly obovate, nar- 

 rowed to a short petiole, 2 to 5 lines long; involucre solitary, turbinate, 2 to 

 21/2 lines long, with erect teeth ; calyx whitish or pinkish, glabrous, stipe-like 

 at base, 3 to 4i^o lines long, its segments obovate, rounded at apex; filaments 

 pilose below middle. 



Red Mt.. ^Mendocino Co.. Eastwood, not otherwise known. Remarkably 

 similar in all details of habit to the monocephalous forms of E. umbellatum.

 Kellogg. E. caespitosinn var. kelloggii Jones, Contrib. 11: 7 (1903). 



65. E. alpinum Eiigclm. White-lanate dwarf. 1VL> inches high, the scape- 

 like stems with a whorl of bracts at the middle and ending in a single in- 

 volucre; leaves roundish, 5 to 7 lines broad; involucre turbinate. 3 lines 

 long, with minute teeth ; calyx yellow, glabrous, li o to 2 lines long, the stipe- 

 like base short, the segments obovate, obtuse ; filaments slightly pubescent 

 at base. 



Mt. Eddy. Siskiyou Co., 8700 feet. Copdaiid. 



Eefs. — Eriogonum alpisiim Eugclm. Bot. Gaz. 7: 6 (1882), type loc. Scott Mts., Geo. 

 Engelmann. E. copelandi Greene in hb. E. alpinum and E. copclandi are "in my opinion 

 undoubtedly eonspecific. The only diflference is that the Engelmann specimen has slightly 

 larger leaves but the inflorescence characters are identical.'' — J. M. Greenman, Mo. Bot. Gard.

CHENOPODIACEAE. Saltbush Family. 

 Herbs or .shrulis, mostly salt-loving, very often succulent or scurfy, with 

 alternate or rarely opposite leaves, or leatless. Flowers small (1 or 2 lines 

 long), perfect or unisexual with an herbaceous calyx of 5 or fewer sepals, 

 or in the pistillate Hower the calyx sometimes absent. Stamens as many as 

 the sepals and opposite them, or fewer, distinct or slightly united at base. 

 Ovary superior, 1-celled, containing a single ovule, becoming in fruit an 

 achene or utricle. Styles or stigmas 2 or 3. Embryo curved ; endosperm 

 copious or sometimes wanting. Nitroi)hila has a scarious calyx and stamens 

 not distinct. — About 75 genera and 550 species, mostly of alkaline deserts 

 or steppes, and occurring all over the earth.
