96 PLANTE FENDLERIANE. 
p. 368. Deep sand between Rabbit’s Ear Creek and Willow Bar, Sept., and in the 
sandy bed of Dry Creek, near Bent’s Fort. (455.) — Dr. Wislizenus gathered it in New 
Mexico, at the northern extremity of the Jornado del Muerto; with the peepee trifid 
rays, as im Fendler’s specimens, half an inch lon

Margin of fields, Santa Fé; July, Aug. (458.)— Root annual. Stems 6 inches high, 
branched from the base ; branches corymbose, bearing single or few heads (about as large 
as those of S. (Achyroppapus) senecioides, Nees) on slender peduncles, Leaves | 
somewhat cinereous; the uppermost entire, and like the segments of the others, only 
half a line wide. Scales of the involucre about 10, pubescent outside, nearly as long as 
the disk. Achenia slender, conspicuously hairy on the angles towards the attenuated 
base. Branches of the style tipped with a very short conical appendage. Corolla yel- 
low. — This plant entirely accords with Achyropappus except that it has no rays. It 
closely resembles Schkuhria multiflora, Hook. § Arn. (in Jour. Bot. 3. p. 322), from 
Mendoza, which is also rayless ; but the pappus of that species consists of narrower and 
acutish palez, less thickened at the base, the alternate ones with a percurrent, or some- 
times excurrent, midnerve. These plants, therefore, with the uniligulate S. Bonariensis, 
Hook & Arn. l. c., appear inevitably to connect, not only Achyropappus, H. B. K., but 
also Amblyopappus, Hook & Arn. in Jour. Bot. 1. c., with Schkuhria; one of the 
species of which (S. virgata, DC.) is said sometimes to want the solitary ray. Unless 
there is some diversity in-habit beyond what the published character of Amblyopappus 
would indicate, this name should be preserved for the section of Schkuhria comprising 
these many-flowered homogamous species with awnless pappus.— Hopkirkia, DC., it 
would appear from a plant in the collection of Dr. Wislizenus,* must also be reduced to 
Schkuhria. . . 
Garden. Some indigenous specimens of the latter, gathered in Texas by Mr. Wright, have many of the 
achenia with an abortive pappus. Mr. Wright has also communicated some fruits of what would appear to be 
the same species, except that the achenia are glabrous, and entirely destitute of pappus.
