ACROCLINIUM roseum; glaberrimum, caulibus sulcatis, foliis linearibus acumi- 
natis, involucri squamis exterioribus subappresse patentibus, receptaculo 
planiusculo pilosiusculo. : 
A native of the interior of South-west Australia, between the 
Moore and Murchison rivers, from whence the seeds were sent 
in 1853 by Mr. James Drummond, together with dried speci- 
mens (No. 157 of his Herbarium). It flowered freely in the 
Royal Gardens at Kew during the present summer, and forms 
a graceful greenhouse annual, conspicuous for its bright rose- 
coloured heads and pale stems and leaves. Our garden speci- 
mens are considerably larger than the wild ones, both in stature 
and the size of the flowers. Though differing from the previ- 
ously-described species of Acroclinium in the flat receptacle, we 
have no hesitation in referring it to that genus, and have modi- 
fied Professor A. Gray’s generic character in consequence. ‘The 
other species, of which three are enumerated in“the ‘ London 
Journal of Botany,’ are all natives of South-west Australia, as 
is a fifth and new one, sent to us from the same country by our 
intelligent correspondent Mr. Roe, the Colonial Surveyor.
