very irregular and but 1-2-winged or wingless ; seed li" long. — Distinguished 

 especially by its broad scarious involucre and its not indurated nor crested 

 fruit; varying considerably in pubescence, the present specimens having 

 rather more than usual. From Northern Arizona and New Mexico to Salt 

 Lake Valley, the Platte, and Council Bluffs, Iowa. Foot-hills near Salt Lake 

 City and sandy shore of Stansbury Island; 4-5,000 feet altitude; May, 

 June. (965.) 



Abeonia. turbinata, Torr., in Herb. Annual, viscid-pubescent ; stems 

 i-l° long, prostrate or subascending ; leaves 4-1 j' long, broadly ovate or ob- 

 long, glabrous or slightly pubescent on the margin, cordate, truncate, or some- 

 times cuneate at base, obtuse or rarely acute, sometimes sparingly sinuate- 

 dentate, usually exceeding or about equaling the petioles ; peduncles usually 

 elongated and exceeding the leaves ; involucral bracts 2-6" long, mostly 

 linear-lanceolate, acurninate ; flowers numerous, 6-8" long, pinkish ; limb 

 5-parted, 4" broad ; stamens unequal ; fruit 3-4" long, thin-coriaceous, the 

 narrow hollow wings crested above in the perfect fruit with transverse disks ; 

 seed 1" long. — Body of the fruit not at all thickened and rigid, as in A. um- 

 bellata and A. mellifera, the wings frequently more or less aborted, but in the 

 normal form straight and equal, each terminated by a circular disk. From 

 New Mexico and Arizona to Southern California (?) and Nevada. It is 1710 

 and 601 Wright, and 93 Wislizenus, from New Mexico ; was collected by 

 Emory and Dr. Palmer in Arizona, and by Stretch and Dr. Torrey (455) in 

 Western Nevada. Fremont's specimens from the Mohave River are probably 

 the same. It may be the A. speciosa of Buckley, from Fort Belknap, New 

 Mexico, but the description is too meager for the identification of the species-
