770 SUPPOSED NEW GENUS OF THE N.O. MYRTACEJi, 



think the systematist is justified in separating them. The 

 gradation of generic characters l:)etween the former genus and the 

 latter is much more marked than between the latter and the 

 genus Verticordia. One of the characters wanting in this hiatus 

 will be found, I think, in the new genus. 



The most constant character of this plant is its nodding, 

 pedunculate cluster of two flowers. A sub-sectiou of Darrvinia 

 has some of the flowers nodding, but the calyx-lobes and pedicels 

 differ from those of the species now described. 



Another character which distinguishes it from the three genera 

 above mentioned is that the flowers are not crowded in heads as 

 in D.iricinia and Ilomoraiithus, nor in corymbs as in Verticordia. 



It is allied to Darwinia and Hoinornntlius by its calyx and 

 anthers, but difl^ers from them in its calyx-lobes as above 

 mentioned, and also by its few pedicellate flowers. 



It differs from the two sections of Verticordia mentioned by 

 i3entham (B.Fl Vol. iii), principally in the shape of its anthers, 

 as well as in other minor points. 



The bracteoles are not thick or scarious as in its congeners, nor 

 are they keeled as in Darwinia ; they are folded well over each 

 other and are rather persistent. 



The lobes of the calyx are fewer than generally pertain to 

 Verticordia, and thus the gradation from the single lobe of Homo- 

 ranthus to the extreme, subulate, plumose lobes of Verticordia 

 is apparently complete. 



It is only the calyx-lobes and peltate placenta that connect it 

 with Verticordia, and therefore I do not think I am justified in 

 placing it under that genus. 



The anthers and staminodia are identical with those of 

 Darwinia and Homoranthus, but differ in shape from both the 

 porose and the longitudinally opening anthers of Verticordia. 



The inflorescence of Verticordia, which is mostly corymbose, is 

 quite different from that of Rylestonea. Through the kindness of
