dentibus calloso-mucronatis, corymbo terminali 3-5-cephalo, 
involucro late cylindrico bracteolis lineari-subulatis pilosis caly- 
culato. 
Has. Near Villa de Arrayas, Province of Goyaz (3868), and on 
the ascent of the Corcovado, near Rio de Janeiro (5527). 
Herba annua, 2-3-pedalis, Folia caulina 5-8 poll. longa, radi- 
calia majora, subtus pallida.  Involucrum 6 lin. longum, 
squamis linearibus acuminatis pilosiusculis margine scabridis. 
Capitulum multiflorum, floribus marginalibus  multiserialibus 
fcemineis tenuissimis 5-dentatis, centralibus hermaphroditis 5-den- 
tatis. Receptaculum planum, nudum, minute subpapillosum. 
Styli rami cono superati. Acheenia oblonga, 10-costata, inter 
costas pilosa. Pappus albidus. 
l have been unable to refer this plant, which seems, indeed, 
a very variable one, to any described species. It appears to 
come nearest the E. carduifolia, DO. In n. 3868 the leaves are 
coarsely and irregularly inciso-dentate, while in the other number 
they are deeply pinnatifid: in all other respects they are not 
different. 
5790. E. (Neoceis) Organensis; caule herbaceo erecto sulcato 
ramoso pilosiusculo, foliis pinnatisectis, lobis utrinque 3-5 
Imearibus aut rariter subdentatis supra glabris subtus pilostus- 
culis, capitulis erectis in paniculam corymbosam laxam dispo- 
sitis, involucri cylindrici squamis linearibus acutis flores sub- 
æquantibus. 
Has. Open places on the Organ Mountains, at an elevation of 
about 3000 feet. March, 1841. 
Herba annua bipedalis. Folia subcoriacea. Involucrum 44 lin. 
longum. Achzenia oblonga, 10-costata, inter costas hispida. 
Pappus roseo-hlacinus. 
Near E. valerianafolia, DC., from which it is distinguished by 
its hairy stem, more coriaceous leaves, having much narrower, 
scarcely denticulate, segments, and considerably smaller capitula. 
The achenia of E. valerianefolia are longer, and villous rather 
than hispid, which they are in the present plant.
