Melbourne, I have had the opportunity of comparing the latter 

 with a large number of species of the former, and the difference 

 is quite marked. 



The pedunculate, pedicellate inflorescence is very characteristic, 

 and the two pedicellate flowers have, I believe, no parallel 

 amongst the species of the cognate genera. 



Homoranthus has rarely, if ever, only two flowers, and then 

 these are not pedicellate nor pedunculate. 



The distinct exsertion of the style is a character which allies 

 it more with Darwinia than with the other two genera. 



Of all the Verticordias it is pei'haps more closely related 

 to V. Wilhelmi, F.v.M., than any of the others, and this is 

 the first species of that genus, so that Rylstonea, having calyx 

 and anthers similar to those of Darwinia and Homoranthus, and 

 calyx-lobes and placenta of Verticordia, I place it in botanical 

 sequence between this latter genus and Homoranthus.
