A remarkable Boragineous plant, distinguished, as a Genus, 
by Mr. Nuttall, to whom I am indebted for the specimens 
here figured. That able botanist remarks that its flowers have 
an agreeable odour, and open towards sunset as in Mirabilis. 
He contrasts the Genus with Arguzia ; and Mr. Bentham has 
pointed out its near affinity with Schleidenia, Endl. (Presiea, 
Mart. Noy. Gen. Bras. 2, p- 75, t. 164. The resemblance is 
very close indeed; but the latter genus has a deeply lobed 
corolla, with 5 appendages or little hooked seales in the sinuses, 
and 5 tufts of hairs in the tube, filaments to the stamens, a 
short persistent style, and a small conical apex to the stigma, 
_ instead of a tuft or pencil of hairs,
