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 co! 
determination may be obtained. Prunus Zappeyana ? var. subsimplez has been 
omitted as being of a too doubtful position. 
CowsPECTUS SPECIERUM QUARUM FLORES NOTI. 
Folia semper acuminata. Sepala semper, saepe parce, brevissime glanduloso- 
fimbriolata. Cupula glabra (excepta in P. micromeloide). 
Flores coaetanei. 5 
Sepala intus plus minus pilosa. Petioli 6-10 mm. glabri v. superne parce pilosi.
