It has been impossible to draw up a good conspectus of the species of this group, 

 as the flowers of five species are unknown, and I have been obliged to separate 

 those of which the flowers are known from those of which only the fruits are known 

 and to indicate the distinguishing characters more fully, that in some degree a correct 

 determination may be obtained. Primus Zappeya7ia ? var. subsimplex has been 

 omitted as being of a too doubtful position. 



Conspectus Specierum quarum Flores noti. 



Folia semper acuminata. Sepala semper, saepe parce, brevissime glanduloso- 

 fimbriolata. Cupula glabra (excepta in P. micromeloide) . 

 Flores coaetanei.
