terminal, short, three-flowered. Calyx urceolate in its 
tube, with ten rather obscure elevated lines, and cut at the 
margin into five, linear-reflexed, hispid segments. Corolla 
of five petals, each oval, acute, the extreme point generally 
reflexed, pure white, the margin ciliated; the insertion is 
upon the margin of the calyx, between the segments. 
Stamens ten, alternate five shorter. Filaments white, erect : 
Anthers linear, oblong, yellow, transversely wrinkled, pro- 
truded into a didymous spur at the base, the extremity 
attenuated in a slight degree, brown, and there opening 
with a large pore. Pistil: Germen oval, hid by the per- 
sistent calyx, obscurely striated: Style straight, erect, 
filiform, as long as the stamens: Stigma obtuse, glandular. 
Seeds of this plant were received from Mr. Locxuarr, of 
Trinidad, with many other rarities, in 1827: but the plants 
raised in the stove promise to be only of annual duration. 
The blossoms a Widimmnary. > 
This genus has been recently established by the Professor 
De Canpo.te, who observes, that it is to be distinguished 
from another new Genus, Lastanpra, by its smooth stamina 
and inflorescence ; from Arrurostemma, by the quinary, 
and not quaternary number of the parts of the flower; from 
Ossecx1a, by the absence of appendages between the lobes 
of the calyx ; and from Metastoma by the fruit being cap- 
sular and free. The species are usually shrubs, and all 
from South America.
