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 and 

 styles. 



From all the race of Byttneriaceae, to which this belongs, 

 it difi^ers 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 (rrupoQ sterile, in allusion to the want of 

 sterile stamens.
