No. 1723, 
GREVILLEA SULPHUREA. 
Class. Order, 
TETRANDRIA MONOGYNIA. 
A native of New South Wales: we raised 
it from seeds in 1826. Mr. Brown has de- 
scribed it in his valuable Supplementum, 
which he has lately presented to us, and 
which contains such an astonishing number 
(nearly 200) of new species of Proteaceæ 
alone, all found since he published his Pro- 
dromus. If in one single order so much has 
been discovered in New Holland, what in- 
deed must there be in that immense country 
of all other plants! 
This species requires the protection of 
the greenhouse : it flowers in May, growing 
to the height of two feet and upwards. It 
should be potted in sandy peat soil, and 
will increase by cuttings.
