venas pubescentibus inferioribus oppositis, capitulis paucis longe pedunculatis, involucri 
bracteis exterioribus minoribus squarrosis, interioribus subscariosis obovatis ciliatis, paleis 
striatis dorso ciliatis, floribus flavis, ligulis multistriatis, disci corollis pubescentibus, acheniis 
compressis glabris. 
Herba erecta, scabrida, ut videtur caulibus basi simplicibus, oligocephalis, striatis, purpureis. Folia

ovata, oblonga vel lanceolata, usque ad 3 poll. longa, obtusiuscula, subtrinervia, supra strigilloso- 
scabrida, subtus in nerviis venisque strigillosa, inter venas albido-pubescentia. Capitula longe 
pedunculata, circiter 14 poll. diametro, pedunculis subaphyllis sub involucro longe squamoso- 
pilosis ; involucri bractez 3-seriata, subcoriacez vel interiores fere scariose, ciliatz, obovate, 
exteriores breviores, calloso-acuminatz, squarrose, interiores apice rotundate ; receptaculum 
convexum ; palez complicate, striate, acuminate, dorso ciliate, floribus vix breviores. lores 
radii neutri, flavi; ligule oblongz, ad 9 lineas longe, apice subintegre, multistriate (13-15), 
leviter puberule. Flores disci numerosi, flavi; corollze infundibuliformes, pubescentes.

laxe corymbosis, involucri bracteis nonnullis amplis glabrescentibus, paleis tenuiter scariosis 
preter costam glabris apice sepissime 3-5-dentatis ; disci corollis infundibuliformibus hirsutis 
basi achenia obtegentibus. 
Herba erecta, ramosa, ramis striatulis, cito glabrescentibus. Folia caulina alterna, subsessilia, 
lanceolata, 8—5-pollicaria (superiora gradatim minora) utrinque valde attenuata, acuta, subtri- 
nervia, integra vel obscure denticulata, supra scabrida. Capitula numerosa, laxe corymbosa, 
pedunculis graciliusculis, erectis; involucri bracteze subcoriacee, resinifere, glabrescentes, 
exteriores lanceolate acute, interiores majores, oblongo-obovate, usque ad 5-6 lineas long 
et 2-8 lineas late ; receptaculum convexum vel fere conicum ; pales ample, tenues, subsca- 
riose, complicate, flores amplectentes, apice sepissime 3-5-dentate, costa leviter scabride. 
Flores radii neutri, pauci, 6—7 lineas longi. Flores disci numerosissimi; corolle infundibuli- 
formes, hirsute, basi achenia obtegentes. Achenia nigra, glabra, subtetragona, compressa.
