Nota. Genus Gautleyae re vera. Roscoeae valde afflnis at corollae lobe postico anteriores 

 subaequante non multo latiore et colore florum luteo ab eo mea sentontia haud male diversum. 

 Semina cujusque loculi capsulae in massas conglutinata characterem minus essentialem praebent 

 qui in genera Roscoeae ad hunc usque diem non ubique notus evadit.
