DOODIA ASPERA. 
Class. Order. 
CRYPTOGAMIA FILICES. 
This Fern is from New South Wales, and 
recorded by Mr. Aiton to have been intro- 
duced in 1808. It isa very elegant plant. 
The soil which seems to agree best with it is 
sandy peat, and it should be liberally sup- 
plied with water. It seems to thrive best in 
a moderate stove heat, and throws up side 
shoots occasionally, by which it is propa- 
gated; the best season for separating them 
is in the spring.
