This most distinct genus, the propriety of the name of which 

 will be recognised by everybody, has sufficient characters to deter- 

 mine its affinity without any doubt. True porous anthers occur in 

 the family only in the Martalmn Ophiorrhiziphyllon, which, how- 



', has two bilocular anthers and no retinacula to the seeds. 

 Ctirdtmthera (Adenosma, Nees) is the only genus, besides the one 

 here described, with non-indicated retinacula; but besides the 

 entirely different corolla, andrcecium, habit, &c, our plant has 

 imbricated and not contorted aestivation of the corolla. Its place 

 is doubtless between Opkiorrhiziphylkm and Cardanthera ; and it 



links together the tribe Xetmmiea and Rudliee, sub-tribe Hygivpkilem.
