FLORA OF BRAZIL. 411 
Has. Dry upland Campos between Arrayas and San Domingos, 
Province of Goyaz. May, 1840. . 
Suffrutex 3-pedalis. Folia 14-2 poll. longa, angustissima. 
Pedicelli brevissimi, ad apicem incrassati, striati. Involucrum 
cylindricum, 9 lin. longum, squamis 3-nerviis, margine mem- 
branaceis, 14 lin. latis, achænium 33 lin. longum. 
This comes very near P. dineare, DC., of which I possess 
numerous specimens from different parts of Brazil, but may be 
distinguished from it by its numerous leaves, shorter pedicels, 
narrow cylindrical, not oblong, capitula, involucral scales a third 
longer, its very much narrower, shorter achænia, and longer and 
less scabrous pappus. The involucrum is almost that of P. pre- 
nanthoides, DC., but shorter; while the leaves are like those of 
P. lineare, only narrower.

dricum, squamis pluriserialibus adpresse imbricatis siccis, exte-

parvum, conicum, nudum. Corolle tubulosæ, 5-fidæ. Anthere 
ecaudatæ, exsertæ. Styli rami apice truncati, subcapitati, his- 
piduli. Achænia lineari-oblonga, tetragona, resinoso-punctata, 
villosa. Pappus uniserialis, paleis circiter 12 scariosis enerviis 
lineari-lanceolatis acuminatis ad apicem lacerato-pilosis. —

corymbum amplum compositum. dispositis; floribus luteis. 
This genus is established for the reception of two plants, one 
of which was collected by myself in Brazil, the other is Calea ? 
gentianoides, DC. : The latter, indeed, I have not seen, but, 
judging from De Candolle’s description, I have no hesitation 
in considering it a congener of my plant. The latter has very 
much the habit of Lemmatium, DC., and of some species of
