 emarginato-bifida, minute reticulata, areolis oblongis. Stipidcc 

 rotundatae, planiusculse apice bifidae, marginibus spinuloso-den- 

 tatis. Calyx terminalis, foliis perichaetialibus laciniatis basi cinctus, 

 sesquilineam longus, oblongus, purpureus, subplicatus, versus

Among several very interesting plants obligingly communi- 

 cated to me by Mr. Burchell from Rio Janeiro, is the present 

 beautiful variety of a species, which has already been found 

 in Jamaica and in the Isle of France. It appears therefore 

 to have a widely extended geographical range.
