Has. In cane-fields near Crato, Province of Ceará, Oct., 1838 
(1728); and in similar situations near Arrayas, Province of 
Goyaz, March, 1840 (3848). 
Annuum, 1i—3-pedale, erectum, ramosum. Folia opposita, 
summa alterna, 3-42 poll. longa, 1-2} poll. lata: petioli villosi. 
Tnvolucrum 3 lin. longum. Ligule late oblongæ, obtusissime, 
obtuse bidentate. 
1729. E. Zanceolatum ; ramis adpresse piloso-scabris, foliis petio- 
` latis ovato-lanceolatis versus apicem valde attenuatis acuminatis 
basi obtusiusculis serratis tri- vel subtriplinerviis utrinque ad- 
presse piloso-pubescentibus scabridis, pedunculis terminalibus 
subcorymbosis, involucri squamis exterioribus oblongo-lanceo- 
latis acutis hispidis, interioribus paleiformibus. 
Has. Near Aracaty, Province of Ceará. Aug., 1838. 
Annuum, 2-3-pedale, erectum, ramosum. Rami superiores di- 
chotomi. Folia opposita, summa alterna, 3—43 poll. longa, 6-12 
ln. lata: petioli 4-6 lin. longi, villosi. Involucrum 3 lin. 
longum. Ligulæ late oblongæ, obtusissimæ, obtuse bidentate. - 
This differs principally from the preceding species in its stouter 
habit, much narrower leaves, and less acuminated involucral scales. 
The acicular points of the scales of the receptacle are also one 
half shorter. 
3848 (bis). E. angustifolium; ramis subscabris, foliis petiolatis 
lineari-lanceolatis utrinque attenuatis subtriplinerviis distanter 
dentatis utrinque adpresse piloso-pubescentibus scabridis, pedun- 
culis terminalibus subcorymbosis, involucri squamis exterioribus 
lanceolatis acuminatis, interioribus paleiformibus. 
Has. Near Sapé, Province of Goyaz. Feb., 1840. 
Annuum, bipedale, erectum, ramosum. Folia 3-6 poll. longa, 
6-10 lin. lata: petioli villosi. Involucrum 3 lin. longum. 
This differs from both the preceding species in its much nar- 
tower leaves, which are besides truly dentate, not serrate.
