NOTES ON THE GENERA DARWINIA HOMORANTHOUS AND RYLSTONBEA. 63 
The chief characters of the two species referred to above 
under this subsection are as follows:— 
“Leaves mostly opposite, triquetrous or laterally flattened. 
Flowers 2 to 4in the head. Petals ovate. Staminodia 
small and subulate.’’—D. tawxifolia. 
**Leaves semiterete. Flowers sessile or nearly so. Calyx 
5-ribbed, smooth.’’—D. fascicularis. 
HOMORANTHUS. 
The genus Homoranthus was established by A. Cunning- 
ham (in Schau. Myrt. Xeroc. 191, t. 3, 1840), on specimens 
collected on Islands of Moreton Bay, Queensland. In 
addition to H. virgatus, which is the type of the genus, 
Ounningham described another species under the name 
flavescens, from specimens collected in forest lands skirting 
Liverpool Plains and Molle’s Rivulet below Wellington 
Valley. Bentham l.c., united it with H. virgatus, saying 
that he could not discover any difference whatever between 
the two species. 
VERTICORDIA. 
This genus was established by A. P. DeCandolle, who 
took up the species published under the name Chamee- 
laucium plumosa by Desfontanes in Mem. Mus. Par. V, 42, 
t. 4, 1819. The specific name plwmosa, should therefore, 
be the type of the genus, and not V. Fontanesii of 
DeCOandolle, which was not published until 1828, vide DC., 
Prod. iii, 209, 1828. 
Bentham established two sections for the species of this 
genus, namely, Sect. I. Huverticordia with the following 
characters :— 
“Anthers nearly globular, opening in two almost dorsal pores; 
connective either small and inconspicuous or more or less thickened, 
or produced into a concave or hooded appendage concealing the 
pores. Ovules 2 or rarely 4 or 1, on a small or stalk-like placenta.”
