A very singular-looking small tree, but I fear generically undistinguishable 
from Senecio, from which it differs technically only in the want of sphacel ated 
apices to the involucral scales, a character of no constancy in Senecio itself. 
Until, however, the Senecionideous genera are wo orked up from the pew ma- 
extent that heterogeneous Tribe may require subdivision® De Candolle’s L. 
Leucadendron is a totally different genus (Pladarozxylon, Tab. wen 1055), 
and his doubtful L. euneifolia is probably an Aster.—J. D. Hoo
