two pores more or less confluent within. The flowers are in 
terminal capitules and situated in the axil of narrow or often 
wide and coloured bracts, forming a petaloid involucre. The 
sepals are mutichous, sometimes glandular at the summit. Actin- 
odium is a Darwinia with tetramerous diplastemous flowers and 
stamens not accompanied by sterile tongues. Homoranthus on 
the other hand, has these tongues in the intervals of its ten fertile 
stamens, for its flower is pentamerous and in other respects it is 
quite that of a Darwinia, but the sepals are attenuated at the 
summit to a long subulate point, as we shall find those of Calythrix 
are; and this character, which otherwise would be of the smallest 
importance has been thought sufficient here to distinguish this 
quite artificial genus.” 
Having given a brief summary of the characters on which 
the above mentioned genera were founded, we will now 
bring under notice three other species which appear to me 
to have characters very similar to those mentioned above, 
namely, Darwinia Schuermanni Benth., (Schuermannia 
homoranthoides F.v.M.) from Boston Point, Port Lincoln, 
S.A., D. Thomasii Benth., a Queensland plant, and D. 
verticordina Benth. The calyx-lobes of the two latter 
are described as “‘ very shortly and irregularly denticulate- 
ciliate’’ and ‘“‘minutely denticulate.’’ In D. Schuermanni 
(which by the way is to be found in the same locality as 
D. Wilhelnii), the flowers are solitary in the upper axils, 
of short ‘branchlets, on very short pedicels. It will thus be 
seen that, in addition to D. Wilhelmii, there are two other 
species which occur, in South Australia and Queensland 
respectively, and if geographical distribution is to be taken 
into consideration, this fact should be as important as the 
point made by Mr. Baker, in connection with D. Wilhelmii, 
viz:—‘‘so far from the home (Western Australia) of Verti- 
ecordia.’’ In establishing the genus Rylstonea, Mr. Baker 
states,*
