A handsome stove-plant, received from Professor Jameson, who 
detected it in the vicinity of Guayaquil. It belongs to M. Alphonse 
De Candolle’s first section of the genus “Lobi calycis breves, 
obtusissimi,” and to the second section of the species “ Flores 
albi, Zvtei vel ex luteo variegati.”. Yet in that group there is 
no species the description of which satisfactorily accords with 
this. Its great beauty consists in the fine red of the peduncles 
and pedicels and outside of the flower, and the rich yellow of the 
upper or inner side of the corolla, and which, together with the
