1. Nectouxia formosa, H. B. K. ii. 10. tab. 193 ;—herbacea, 
caule angulato ; foliis cordatis, ovatis, acutis, hirtellis ; calyce 
piloso-hispido, corolla flava, staminibus tubo haud superan- 
tibus.—Mexico (Real del Monte). 
This plant is described as being scarcely 8 inches in height 
with a fusiform root: its leaves, sometimes geminate, are from 13 
to 13 inch long, and | to 1} inch broad, upon a petiole 9 to 10 
lines in length : the peduncle of its solitary axile flower is half an 
inch long, its calycine segments 6 lines, the tube of its corolla 
10 lines, the lobes of its border 7 lines and 33 lines broad. 
2. Nectouwxia bella (n. sp.) ;—herbacea, caule striato ; folus cor- 
datis, ovatis, acutis, utrinque sparse et mollissime pubescen- 
tibus; flore cernuo, staminibus infra faucem corolle omnino 
inclusis, filamentis superne in ligulam latam membranaceam 
expansis.—Mexico (Real del Monte, Coulter, no. 1270 ;—cirea 
Tolucam, Andrieux, no. 180). 
Although found near the same locality, and in no way differ- 
ing in the shape of its leaves, its herbaceous stem and tapermg 
root, this plant offers many points of structure at variance with 
the foregoing species, if we depend upon the usually accurate 
descriptions of Prof. Kunth. It is double its height, and its 
leaves are proportionally larger, being often geminate, 27 inches 
long, 2 inches broad, upon a petiole 3 inch in length ; the pedun- 
cle of its axillary flower is 1 inch long, its narrow linear acute 
calycine segments are } to 3 inch, the tube of its corolla 1 inch to 
1+ inch in length, and 2 to 3 lines in diameter at the mouth ; the 
lobes of its border are lanceolate, oblong, very patent, and # inch 
long; the corona, with ten obsolete teeth, protrudes 2 lines be- 
yond the throat; the stamens, inserted somewhat above the middle 
of the tube, are 3 lines long ; the ovarium 1s elongated and point- 
edly conical, 3 lines long, 3 line at base, and is seated on a pro-
