Notes on the genus Raoulia.—The genus Raoulia may be considered as one 
of the best represented in New Zealand, both as regards number of species, 
and abundance of plants. Not only do they enjoy an almost entire immunity 
from fire, but they increase and spread on the ashes of other plants, they 
flourish on the most barren ground, and cover poverty of soil and gravels with 
much floral beauty; on river flats and mountain sides they are equally 
abundant, proving useful as sand-binders, or in fixing springy hill slopes. 
They may be considered worthless as food, and, in fact, were they other- 
Wise, it would be almost impossible for stock to break in on the hard, close, 
compacted masses of such species as Raoulia eximia, or R. mammillaris, the 
Vegetable sheep of the shepherds. The species of this genus collected were 
Raoulia australis, R. tenuicaulis, R. hectori, R. m‘kayi, R. parkii, BR. sub- 
Serica, R. glabra, R. mammillaris.
