ol Small: Studies in 



The type was collected in the mountains or northern Lower 

 California, August 8, 1884, by Mr. C. R. Orcutt. 



Eriogonum glaucum. 



Annual, slender, acaulescent. Leaves basal ; blades ovate or 

 oval-ovate, 5-10 mm. long, obtuse, undulate-crisped, often inequi- 

 lateral, softly hispid on both surfaces, obtuse or subcordate at the 

 base; petioles 2-3 times longer than the blades, hirsute: scapes 

 erect, solitary or several together, 1-6 cm. tall, glaucous, forked, 

 the branches ascending or spreading : peduncles filiform, about 1 

 cm. long, more or less spreading : involucres glabrous, turbinate, 

 1 mm. long ; segments oblong, obtuse, about as long as the tube : 

 calices densely hirsute, 2 mm. long; segments lanceolate, acute, 

 erect ; filaments glabrous. 



Closely related to Eriogomnn trichopes and E. inflatnm. Leaf- 

 blades less rigid, less prominently nerved and more densely pubes- 

 cent. Scapes more sparingly branched and involucres fewer than 

 in either of its relatives. The lanceolate calyx-segments also serve 

 to separate it from both relatives. 



The type specimens were collected by Mr. C. R. Orcutt, in 

 the Colorado Desert, in April, 1889. 



Eriogonum capillare. 



Annual, slender, acaulescent. Leaves basal ; blades orbicular- 

 ovate, 1—2 cm. broad, acutish or apiculate, finely undulate crisped, 

 truncate at the base or subcordate, sparingly strigose on both 

 sides ; petioles about as long as the blades, tomentose : scapes 

 erect, 4-5 dm. tall, simple below, forking above, the ultimate 

 divisions filiform or hair-like, 1-4 cm. long, erect or spreading: 

 involucres turbinate, about 1 mm. long, glabrous; segments 5 

 oblong or ovate-oblong, obtuse : calices glabrous, about 1 mm. 

 long, long-exserted, urn-shaped, pink ; segments oblong, slightly 

 dilated at the apex and slightly revolute about the middle, the 3 

 inner somewhat narrower than the outer: filaments glabrous, 

 short: achenes 3-angled, 1 mm. long; base swollen; beak slightly 

 shorter than the base. 



Another relative of Eriogonion trichopes and E. inflation, but 



readily distinguished by the tomentose pubescence of the leaves as 



contrasted with the hispid pubescence of the two older species. 



The scapes are not symmetrically branched, but rather irregularly 



forking and the peduncles longer than in both relatives. The 



glabrous calices are also diagnostic.
