Mr. J. Miers on the genus Nectouxia. 137 
vaide ramosus, foliis inferioribus obovatis, acutis, imo rotun- 
datis, obsolete dentatis, utrinque fere glabris, venis subpilosis, 
margineque ciliolatis, superioribus lanceolatis, petiolo canali- 
culato sparse pubescente.—Mexico (Papantla, Schzede). 
This plant appears to have very much the habit of a Physals ; 
its lower leaves are 4 inches long, 2} inches broad, on a petiole 
of } to 5 inch; the upper leaves are 24 inches long, 10 lines broad, 
on a petiole of half an inch ; the peduncles are 1 line long; the 
calyx 1 line, and the corolla 2 to 24 lines in diameter ; the calyx 
increases to the size of half an inch, is globular in form, reticu- 
late, and incloses a berry of 3 lines in diameter. 
NECTOUXIA. 
This genus appears to have been little known hitherto except 
from the details given by Prof. Kunth (Nov. Gen. i. p. 10), 
where a figure of Nectouxia formosa is given in plate 198 of that 
work. On comparing a specimen of this genus im the herbarium 
of Sir Wm. Hooker, I am led to conclude it to be a second spe- 
cies, as I can hardly imagine that so accurate an observer could 
have been mistaken. In this species the difference lies in the 
calycine segments being much narrower, in the greater length of 
the corolla, in the segments of the border being narrower, in the 
lower insertion of the stamens, in the longer and more linear 
anthers, and more especially in the singular expansion of the 
upper portion of the filament, and finally m the exsertion of the 
style. Kunth describes his plant as bemg herbaceous and not 
higher than 8 inches, whereas this appears to be a much taller 
plant. Nectouxia evidently approaches very closely to the 
genus Salpichroma, and were it not for the remarkable peculiarity 
of the promiment corona in the mouth of the corolla, it could 
hardly be distinguished from that genus. Like Salpichroma it 
possesses the character of its flowers becoming black im drying : 
the expansion of its filament is also another distinguishing fea- 
ture. I have not been able to examine its perfect fruit, but it is 
evidently a berry: the form and structure of its ovarium quite 
correspond with that of Salpichroma. The following is its 
amended character :— 
Necrouxia. Char. emend.—Caly# 5-partitus, lacmis sequa- 
libus, erectis, linearibus, acutis, persistens. Corolla hypocra- 
teriformi-tubulosa, tubo 5-nervi, 5-angulato, superne paulo 
ampliato, calyce 2-plo longiore, limbo patente, 5-partito, laci- 
nis «zqualibus, oblongis, acuminato-obtusiusculis, estivatione 
induplicato-valvatis, fauce in coronam brevem urceolatam ex- 
sertam 10-nervem 10-dentatam producta. Stamina 5, inclusa,
