This species belongs to Clioiay"s aub-soetioii MiiHiloha' of Sirophlpomaa as laid 

 down in DC. Prod. \'ol. ix. As considered by i)lhers, it would be referred to the 

 section OpcrcuHna; for although the capsule is not strictly ciriaimsoissilo, yet 

 it is clearly differentiatctl into an upper and lower part. A. Peter in Englor and
