Root annual, fibrous. Stem a foot or a foot and a half high, branched, most- 
ly red; every where, as indeed is the whole plant except the coroUa, 
clothed with a soft hairiness or down. Leaves alternate, lanceolate' 
much attenuated, sessile, of a rather rigid texture, singularly waved and 
crisped at the margin, and slightly toothed, nerved, the nerves pale ; 
mid-rib prominent, and red beneath. 
Flowers solitary, axillary, very large, bright yellow, showy. Germen ob- 
scurely 4-sided, red, pubescent. Calyx with the lower part tubular, 
the limb of four segments which remain united, bursting open only on 
one side, the apices furnished with a distinct mucro. Petab obcordate, 
waved. Stamens yellow, with the filaments curved to one side. An- 
thers linear. Style cylindrical, longer than the stamens. Stigmas 4. 
During the early part of the present year, I had the good 
fortune to receive from my valued friend Dr Gillies of Men- 
doza, South America, amongst other rare botanical acquisitions 
of that country, seeds of the present plant. Raised in a hot- 
bed frame, and planted in a warm border, in the month of June, 
the plant produced blossoms plentifully in the month of Au- 
gust, which opened every evening at six, diffusing a powerful 
odour.
