basi angustata, crassiuscula, sub lente trinervia, margine dentibus minutissimis scabriuscula, vel omnino integerrima, 
leviter glutinosa. Capitula ad apices ramorum numerosa, vix 2 lineis longiora, ovata. Involucri campanulati 
squame subtriseriatim imbricate, lineari-lanceolate, margine scariose, acute, dorso virides, leviter glutinose.

gracili, lamina lanceolata acuta subpatente ; styli ramis subulatis glabris. Corolla disci tubulosi, tubo tenui 
glabro, fauce paullo ampliata tubo vix longiore in lacinias 5 lineari-lanceolatas ultra medium divisa.

stigmatifera multo brevioribus. Acheenia oblongo-turbinata, villosa. 
Pappus e setis plurimis ineequalibus 
uniserialibus constans. 
The habit of this plant, resembling in some respects that of Zsopappus, and 
still more that of several Baccharides, is very different from that of most Aplo- 
pappi, of which it has all the essential characters. 
78. ApLopappus (Blepharodon) arenarius, sp. n., suffruticosus, divaricato-ramosus, breviter pu- 
bescens, viscosissimus, foliis oblongis lanceolatisve obtusis sinuato-dentatis undulatis, dentibus obtusis 
rarius aristulatis, involucri hemispherici squamis linearibus apice foliaceis squarrosis. — Cape 
San. Lucas. 
Caules rigide ramosissimi, ramis semipedalibus divaricatis in arena prostratis, Folia crassiuscula, 
semipollicaria vel paullo longiora, superiora minora, uninervia, dentibus paucis seepe valde undulatis, basi 
sessilia vel amplexicaulia, utrinque viridia, pube brevi viscosissima obtecta. Capitula ad apices ramulorum 
solitaria, magnitudine Grindeliw squarrose. Squame involucri numerose, pluriseriatim imbricatz, lineares, basi 
scariosw, apice virides, acutiuscule, squarroso-patentes, extus glanduloso-puberule. Receptaculum brevissime 
alveolato-fimbrilliferum. Ligule ultra 30. 
Achenia turbinato-compressa, sericeo-villosa, Pappi sete 
numerose, ineequales, rufescentes, 
A low plant, with something of the habit of some of the European Pulicarie 
or Franceurie, and not much resembling the generality of Aplopappi, of which 
however it has all the technical characters. 
79. GRInDELIA cuneifolia, Nutt. in Torr. et Gr. FL N. Amer. 2. p. 247?—The specimens 
resemble much those of G. squarrosa, gathered by Douglas on the Red River ; but the leaves are 
but slightly and remotely toothed. The flowers are too much eaten up by worms to show the 
structure of the pappus.—San Francisco. 
ie 80. Hererotueca Sloribunda, Sp. D., erecta, elata, hispida et viscoso pubescens, dense foliosa, 
foliis ovatis grosse dentatis inferioribus petiolatis, supremis sessilibus oblongis, panicula oblonga
