Calophanes Palmeri, Gray, n. sp. Ilirto-pubernla, herbacea ; 

 caulibus simplicibus strictis pedalibus sequaliter foliosis apice 1-2- 

 floris ; foliis ovatis seu ovato-oblongis basi rotundata arete sessilibus 

 (majoribus vix ultrapollicaribus acutiusculis, imis parvulis rotundatis) ; 

 corolla purpurea, tubo gracili subpollicari sepala angustissime linearia 

 glabella bis superante in faucera late obconicam abrupte ampliato, 

 lobis ovato-rotundis ; staminibus 5 fere asqualibus ; antheris oblongo- 

 sagittatis (loculis basi divergentibus parum apiculatis) filamentis tequa- 

 liter dissitis paullo- longioribus ; ovarii loculis biovulatis. — Rio Blanco, 

 in ravines among shaded rocks; July. (160.) Fruit not seen; 

 the flowers being scanty, only one flower-bud was dissected, so that 

 it is uncertain whether the pentandrous character is normal. Pent- 

 stemonacanthus of Brazil is so characterized, and Bentham remarks 

 that only in that plant had an Acanthacea with five stamens been 

 observed.
