witness of the fact, tells us, that the Indians, after rubbing 
themselves with the juice of this plant, handle the Rattle- 
snake without fear of harm. 
The species had not been recorded in any general system 
of Vegetables previous to the appearance of the Synopsis of 
Persoon. It comes very near to the Ipomea sagittata of 
Messrs. Poiret and Desfontaines (the Convotvutus Wheleri 
of Willdenow’s Species Plantarum), a native of Spain and 
Barbary; but there the lower leaves are cordate and only 
the upper sagittate; in all other respects, however, as far 
as we can judge from a middling engraving and the short 
descriptions by which alone sagittata is known’ to us, the 
two resemble each other very exactly, even to the colour of 
the flower, and both are attached to wet maritime spots of 
the mutually distant regions to which they respectively be- 
long. 
Perennial. Root thick. Stem smooth round, twining 
about small bushes, rarely prostrate. Leaves oblongly sa- 
gittate, smooth, entire round the edge, the front lobe much 
broader than the two hinder ones, which are divergent 
longly tapered and sharply pointed: petioles from one to 
two inches long. Flowers large, of a purplish rose-colour; 
peduncles solitary, axillary, one-flowered, stouter than the 
petioles, upright, with two small opposite close-pressed 
bractes situated about the middle of it. Leaflets of the 
calyx upright, imbricately connivent, ovately oblong, 
rounded at the end, nearly equal, three outer ones more 
conspicuously mucronate than the two inner ones. Corolla 
funnelform; limb cornerless; faux of a pale flesh colour on 
the outside, cylindrical, an inch long, 3 times the length of ` 
the calyx. Filaments unequal, bearded at the base. An- 
thers linearly oblong, whitish, upright, sagittate at the 
base. Style longer than the stamens; stigma didymously 
capitate, white, enclosed within the faux. Capsule 2-3- 
valved, 2-celled.
