Characters of some GNAPHALIOID ComPosiTÆ of the Division ANGI- 
ANTHEJE ; by Asa GRAY. 
Some Australian Composite, chiefly of the subtribe Gnaphaliea, having 
been placed in my hands by Sir William Hooker, for examination, I 
here offer the characters of those which belong to De Candolle’s divi- 
sion Angianthee. Figures of the more interesting, now in preparation, 
will appear in the forthcoming volume of the * Icones Plantarum.’ Mr. 
James Drummond’s collections in Sonth-western Australia furnish so 
many plants of this groupe which I am obliged to consider as the 
types of new genera, that it becomes needful to preface the account 
of them with an arrangement of the whole Division. 
This groupe is not so perfectly limited in nature as it is by the cha- 
racter assigned to it by De Candolle. Calocephalus, Br., and Pycno- 
sorus, Benth., want the general involucre altogether ; in Chamespherion, 
&e., it is represented merely by a circle of radical leaves; in several 
genera the capitula are pedicellate, as in Craspedia, where there is merely 
a subtending bract for each; and in the plants which I have referred 
to the obscure genus Crossolepis, Less. the compound glomerule is 
merely subtended by the more crowded uppermost leaves, making an 
evident transition to the Helichrysea, as do Chamespherion and Chtho- 
nocephalus to the Cassiniee. 
The capitula are homogamous in all the known Angianthea, although 
some of the flowers, otherwise perfect, are occasionally sterile by the 
abortion of the ovary, or, in Pycnosorus, according to Bentham, one of 
them is neutral.
