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 exserted trifid 

 rays, as in Fendler's specimens, half an inch long. 



^ 416. Schkuhria (Amblyopappus ? v. Achyropappus ^ ligulis nullis) Neo-Mexicana 

 (sp. nov.) : strigoso-puberula, humilis ; foliis inferioribus pedato-5 - 7-partitis, superi- 

 oribus simpliciter 3-partitis segmentis lobisque anguste-linearibus ; capitulis omnino discoi- 

 deis 30-floris ; acheniis lineari-cuneatis basi ad angulas villosis ; pappi paleis 8 conformi- 

 bus obovatis obtusissimis basi incrassato excepto enerviis corollam subsequantibus. — 

 Margin of fields, Santa Fe ; 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. Sf Am. (in Jour. Bot. 3. p. 322), from 

 Mendoza, which is also rayless ; but the pappus of that species consists of narroAver and 

 acutish paleae, 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 8f Am. I. c, appear inevitably to connect, not only Achyropappus, H. B. K., but 

 also Amblyopappus, Hook Sf Am. in Jour. Bot. I. 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. 

 / * Schkuhria Wislizeni (sp. nov.) : tenella, pube scabra subcinerea ; foliis plerumque trisectis, lobis 

 filiformibus ; involucro unibracteato 4-phyllo 4-5-floro ; floribus omnibus tubulosis hermaphroditis vel unico 

 brevissime ligulato ; acheniis obpyramidalis angulis longe villosissimis ; pappo corollam subrequante, paleis 

 4 ex angulis achenii ovatis obtusis nervo valido excurrente breviter aristatis, 4 alternis similibus sed muticis
