 . Genus iiostro sensu a Sarcostcmmatibus geroiitogeis longe diversum, tarn habitu quam corona ex- 

 teriore corollse nee tubo stamineo adnata. Species typic^ corolla vaklo concava breviter lobata 

 potius Oxysfclmati affines sunt, et, mediantibus speciebus corolla semi-o-fida, arete cum parvifloris alto 

 5-fidis {Sarcostcmmate, H. B, et K,) connectuntur.
