+ 303. CLAVIGERA BRACHYPHYLLA (sp. noy.): subcinereo-puberula, herbacea ; cauli- 
bus humilibus (vix ped.) foliosis ; foliis oblongo-ovatis integriusculis subpetiolatis triph- 
nerviis minutim resinoso-punctatis (3 unc. longis) ; capitulis circ. 12-floris in ramulos suba- 
phyllos vel pedunculos racemoso-paniculatos solitariis paucisve digestis ; squamis involucri 
lanceolatis acutiusculis, extimis brevibus ovatis mucronatis; acheniis pubescentibus ; 
pappo breviter plumoso. — Foot of high rocks, two miles east of the Mora River; Au- 
gust, (339.) — This species is remarkable for a pappus which is almost plumose to the 
naked eye, so as to leave as little distinction between this genus and Kuhnia, on the one 
hand, as there is between it and Brickellia, on the other; the difference being merely 
one of degree. ‘There is an undescribed and remarkable species in Gregg’s collection.* _ 
+304. Kunnta rupatoriowes, Linn. Near Council Grove; August. (340 and 348.) 
— Perhaps the species of Kuhnia of De Candolle with pentagonal achenia and plumose 
pappus may be joined to Carminatia, Moc. §- Sess. ; of which fine specimens occur mn 
Coulter’s Mexican collection. 
+305. K. euratoriorpes, y. cracttis, Torr. § Gray, Fl. 2. p.78. Along the Mora
