His Grace the Duke of Northumberland received this 
plant from the Mauritius, at the end of the year 1833, along 
with Trochetia grandiflora, already figured in this volume 
(t. 21.) It flowered at Syon at the end of March last, when 
our drawing was made. 
The fine broad heart-shaped leaves, and close clusters of 
pink flowers, render it a rather handsome plant. Fig. 1. 
represents a portion of its stamens, and 2, the ovary 
styles. 
From all the race of Byttneriacez, to which this belongs, 
it differs in the want of sterile stamens, with the exception of 
Ruizia. From Ruizia it is distinguished by having a 5-celled 
and not a 10-celled ovary, and not having hairy capitate stig- 
* From a privative, and ørspoç sterile, in allusion to the want of 
sterile stamens. `
