BARNADESIA ROSEA. 
(Lindley.) 
ROSE-COLOURED BARNADESIA. 
This plant belongs to that section of com- 
posite plants to which the name of Mutisiaceas 
has been applied. It is one of the smaller 
groups of species into which this large order 
of plants is divided, and most of its members 
exhibit a singular and very elegant struc- 
ture, and some, as in the case of Barnadesia, 
possess considerable beauty. The Mutisiaceaa 
form one of the two divisions into which the 
labiatifloral composites (that is, those in which 
the hermaphrodite or unisexual florets are 
divided into two lips) ; the other division, 
Nassauviaceae, being distinguished from it by 
certain peculiarities in the structure of the 
stigma and style. 
The Barnadesia rosea is not a very hand- 
some plant in its manner of growth, nor is it 
very prolific of blossoms : it is not, therefore, 
adapted for general cultivation, but may be 
regarded as an example of a very beautiful 
flower when viewed individually, both its 
colour and its structure being exceedingly
