phus; but I rely rather on the strongly five-ribbed fruit, with the 
at length dilated and scarious involucre, to distinguish that genus. 
Quamoclidion, strengthened by this and the following species, 
itseems most convenient to retain as a genus, although it differs 
from Mirabilis only as the first section of Oxybaphus differs from 
he second. While the form of the perigonium of the present 
Species is as in Oxybaphus, that of the following resembles that 
of Mirabilis. |

etectis; foliis breviuscule petiolatis subcordatis acutis ; involucro 
magno glabro campanulato 5-fido 4-8-floro; perigonio infundi- 
buliformi, limbo expanso; staminibus 4~5. Oxybaphus mullti- 
Wislizenus, &c. The involucre is an inch in length; and the 
full-grown perigonium fully two inches long. In the original de- 
Stiption, Dr. " orrey plainly stated that the involucre is “ quin- 
quefid,” and therefore gamophyllous.
