A native of Lewin’s-Land on the southern shores of New 
Holland, according to Mr. Brown, its first discoverer. Allan 
Cunningham collected it at King George’s Sound, Preiss and 
Drummond, at Swan River. The latter sent us seeds, which 
produced flowering plants in the spring of 1847. _ It is a species 
nearly allied to Zsopogon longifolius, Br. (figured in Bot. Reg. 
t. 900), but abundantly distinct as a species. 
Descr. With us this has formed a shrub two to three feet 
high, with rounded, glabrous, fuscous, erect branches. Leaves 
a span and more long, scattered, linear- or oblong- spathulate, 
mucronate, much tapering at the base, glabrous, coriaceous, 
obsoletely three-nerved. A few smaller leaves beneath the capi- 
tulum are villous. Capitulum terminal, hemispherical, formed 
of numerous palish yellow fowers. Scales of the iavolucre imbri- 
cated ; outer ones ovate, scarcely hairy; inner ones narrower, 
‘Villous. Perianth with the tube glabrous, except at the base, where 
it is swollen by the contained gernien, and is hairy. Segments
