Interior of subtropical New Holland, Mitchel/.—This plant has more 
points of resemblance with Leucophyía than with Calocephalus, but it 
is abundantly distinct from both, and strictly belongs to the division 
Helichryseæ, next to Stenocline. Not having been incorporated into 
the Hookeriau herbarium, it escaped my attention when elaborating 
the Angianthee; otherwise it would have been mentioned, along with 
the preceding genus, as exhibiting another evident transition from the 
Angiantheæ to the Helichryseæ*. 
HgrrPTERUM, DC. 
The subgenera here proposed might be altogether separated from 
Helipterum, with nearly or quite as good reason as Hyalosperma, Steetz, 
Rhodanthe, Lindl., Hyridanthe, Lindl, and. perhaps even Schænia, 
Steetz. The following has exactly the aspect of Hyalospermat, but 
the achænia are neither glabrous nor plano-compressed, and the more 
numerous sete of the pappus are barely barbellate: from Schenia it is 
principally distinguished by the few merely infertile central flowers (as 
in many of the allied genera) having the same bifid style as the fertile 
flowers. |
