76 PLANTEH FENDLERIAN2®. 
May. (395.) — Dwarf, more hoary than in the ordinary plant, from which I cannot 
separate it. It is the same as the A. (Blepharodon) Coulteri, Harv. § Gray, ined., from 
California. — Other forms, which I cannot distinguish specifically, were gathered around 
Saltillo by Dr. Gregg. 
7356. A. eracizis: pilosus, humilis; caulibus e radice bienni ramosis; foliis inferio- 
ribus parce pinnatifidis segmentis oblongis obtusis, superioribus integris linearibus sub- 
dentatis, dentibus pulchre setigeris; ramis monocephalis ; involucri campanulati squamis 
3 —4-seriatis lineari-lanceolatis setigero-mucronatis pilosulis ; ligulis 15-18; receptaculo 
valde fimbrillifero, fimbrillis setoso-subulatis achenia subcompressa sericea fere equanti- 
bus; pappo e setis valde inaequalibus, intimis rigidis basim versus incrassatis corollam 
subequantibus, exterioribus gracilibus sensim dimidio—4-plo brevioribus. — Dieteria (Si- 
deranthus) gracilis, Nutt. in Jour, Acad. Philad. (n. ser.) 1. p. 177. — Along Santa Fé 
Creek. (393.) — Our specimen is a very incomplete autumnal one; the pappus whit- 
ish. An original one of Mr, Gambell’s, with which I have compared it, is a plant about 
9 inches high, with slender branches ; the linear leaves half an inch or less in length; the 
heads about the size of those of A. spinulosus; and the pappus rufous. It belongs to the 
section Blepharodon, DC. ; but the pappus consists of as unequal and coarse bristles as 
in the true Aplopappi. The characters of a new Texan species of the same section, which 
has a still more rigid pappus, are subjoined.*

acheniis brevibus turbinatis villosissimis; pappo albo e setis circiter 10 validioribus corollam subzequantibus et 
20-30 sensim minoribus, omnibus rigidis. — Low prairies, near Houston, Texas, Mr. Charles Wright ; Sept., 
Oct. — Stems or branches 6 or 8 inches high, terminated by a loose corymb of five or six showy heads. 
Lower leaves about an inch long, scarcely a line wide, the upper almost filiform. Involucre half an inch in 
diameter ; the numerous golden-yellow rays about the same length. — Of still stouter bristles is the pappus 
of the subjoined rayless species, which should doubtless form a distinct subgenus, viz. : —

marginibus sphacelato-scarios®: pappus achenium et corollam vix adzequans, e setis 20-30 rigidis inzequa-
