NOTES ON THE GENERA DARWINIA HOLOKANTHUS AND RYLSTONEA. 67 
“Tt is on the shape of the calyx and the calyx-lobes that my 
genus is based,—characters upon which Cunningham founded the 
cognate genus of Homoranthus, and which determination was 
supported by Bentham and Hooker, in their ‘Genera Plantarum,’ 
and from these features alone [ think I am justified just as much 
as Cunningham in establishing a new genus on my material.” 
Mr. Baker had apparently overlooked the statements of 
both Bentham-Hooker, and Baillon in connection with 
Homoranthus, which, as stated by them, was retained to 
facilitate the distinction between Darwinia and Verti- 
cordia. In Verticordia everything in the flower is equally 
that presented by Darwinia, but the sepals, usually 5 to 
10 in number are cut up into rather long plumose or ciliate 
strips (except in D. verticordina and V. Thomasii), which 
as already explained, are very shortly and irregularly 
denticulate ciliate. The flowers are also accompanied 
with two lateral bracteoles which are comparatively wide, 
rounded concave and imbricate in such a manner as to form 
around the bud a complete accessory envelope; these are 
very caducous. 
The anthers in both Verticordia and Darwinia are 
practically the same, being more or less globose opening in 
two almost dorsal pores in the former and in the latter 
terminal pores or short slits. The ovary and ovules appear ~ 
to be very variable, as in general the ovary is 1-celled, in 
all the genera under consideration, but the ovules are said 
to be 2, 3, and 4 in Darwinia, 4 in Homoranthus, 2 or 4 on 
a central excentric placenta, or about 8 or 10 on a more or 
less peltate placenta in Verticordia, It is interesting to 
note that the ovary and ovules of Rylstonea cernua are 
practically the same as those of Verticordia as the follow- 
ing particulars will show, as given in Mr. Baker’s descrip- 
tion of Rylstonea, namely, “‘ Ovary 1-celled, about 8 ovules 
on a peltate central placenta, with two processes at the
