I could find no Genus to*correspond with this till some 
months after my drawing was made, when I received from 
my friend Dr. Torrey, the fifth vol. of the Journal of the 
Acad. of Nat. Sciences of Philadelphia, and found a very 
accurate figure and description of a species of the Genus, 
under the name of Strrepranruus (crpegw to turn or twist, 
and avbos, a flower, in allusion to the twisted petals) macu- 
latus. ‘That author discovered his species “ amongst rocks 
and on shelving hills, near the banks of the Kiamesha of 
Red River in Arkansa territory,” and observes that it isa very 
showy and remarkable plant; a character equally applicable 
to our present species, which differs strikingly in the leaves 
from Mr. Nurratx’s S. maculatus. 1t will no doubt bear 
the open air of our climate, though Mr. Murray has hitherto 
had the precaution to keep it in the greenhouse. The 
Genus may rank next to Aranis. 
Descr. Root annual. Stem erect, simple, or branched, 
rounded, glabrous. Leaves few, oblong or more frequently 
elliptical, amplexicaul, with a very deep narrow sinus or 
cleft at the base, obtuse, forming two straight parallel lobes, 
glaucous-green. The branches terminate in long racemes 
of large flowers. Calyx of four ovate, much acuminated, 
membranaceous, pale purple sepals, concave at the base, 
two opposite inserted lower down and more concave or 
saceate at the base. Petals obovate, on long and at length 
twisted claws, fine rose-colour with a very deep lake- 
coloured spot at the base of each limb. Stamens very 
slightly unequal in length. Filaments short, subulate, 
white. Anthers longer than the filaments, pale purple, 
much acuminated, opening chiefly below. Pollen yellow. 
Germen linear. Stigma almost sessile, shortly two-lobed. 
Pod four to five inches long, linear, compressed, but some- 
what tetragonal from the valves having a dorsal carina for 
their whole length: there are besides some obscure veins. 
Seeds in a single series, much compressed, with a rather 
broad, membranous, wrinkled margin. Embryo greenish- 
yellow : Cotyledons flat. Radicle directed to the margins 
of the cotyledons.
