summit.’’? Maiden and Betche in describing Verticordia 
darwinioides state that. the ovary is 1-celled wih 2 ovules. 
Then we have Darwinia Thomasii with 6 ovules. Thus it 
will be seen that the stamens and staminodia, together 
with the anthers and their cells and openings, as well as the 
calyx-tube and the lobes with their digitately-plumose, 
fringed, ciliate or denticulate margins, are extremely vari- 
able in the different genera, and as yet there appears to be 
no distinct line of cleavage in the number of ovules of the 
different genera as defined above. In view of this I pro- 
pose to submit the following descriptive key, which 
embraces those species found in New South Wales, (Jueens- 
land, Victoria, and South Australia, and which are best 
retained in two genera, namely Darwinia and Homoranthus.

DARWINIA, Rudge. 
(Section Genetyllis Benth.) 
A—Calyx-tube narrow, ribbed, the calyx-lobes entire or 
very minutely ciliate or denticulate, not exceeding half the 
length of the petals and often very minute. 
(a) Leaves semiterete, crowded. Flowers sessile 
or, neanlyis0.9.. 0, ; _D. fascicularis. 
(b) Leaves triquetrous, or laterally flattened, 
mostly opposite and bifarius. Leaves 15—20 
mm.long. Flowers sessile, about 8 mm. long, 
usually 4 together in terminal heads. Bracts 
broad, truncate. D. grandiflora. 
Leaves 6—8 mm. long. Flowers sessile, about 
5mm. long. Bracts mucronate-acute, slightly 
longer than the flowers. D. taxifolia. 
Flowers sessile, usually only 2 in the axils of the 
upper leaves, 7 mm. long. Bracts obtuse about 
as long as the flowers. D. taxifolia var. bifiora.
