and retrorse. The other floral characters, however, would 
agree with Micrandra as originally understood: a lobate 
disk in the staminate flower and a thin annular disk in 
the pistillate flower. The staminate flower has eight sta- 
mens, which is rather intermediate between the two 
generic concepts. 
It is obvious from all of the foregoing considerations 
that Micrandra Rossiana is truly an intermediate con- 
cept and that the characters upon which Cunuria has 
rested are unstable. 
Micrandra Rossiana appears to be without close allies 
amongst the known species of the genus.

It is unfortunate that the International Rules of Bo- 
tanical Nomenclature will not permit the adoption of the 
binomial Micrandra Cunuri, which would have avoided 
the use in the same genus of the genitive (see below 
under M. Spruce) and adjectival forms of the same epi- 
thet. There is no possibility of taking up Micrandra 
Cunuri, however, and the new combination made above 
is necessitated.
