514 PROF. OLIVER ON A NEW GENUS OF BEGONIACE E. 
leaves is seen, forms an harmonious mass of colour, which tones down the glaring 
contrasts of scarlet and green. 
* You will perhaps notice that in some specimens the leaves are green on both sides. 
This, I think, is not chance, but is due to a variety.” 
At first sight Begoniella recalls, by its general facies, certain Gesneraceous genera; 
and the general analogy is supported by the four stamens of the male flowers, which are 
easily seen on holding the thin translucent flowers against the light; but examination 
of its floral structure affords no indication of affinity either with this or, so far as 1 can 
see, any other Monopetalous Order. Indeed I do not find that the addition to Begoniacee 
of this anomalous genus, unique in its single gamophyllous perianth and definite stamens, 
suggests any new obvious relation for the Order. 
There remain one or two details in the structure of the flowers which I have not 
satisfactorily cleared up from the pressed specimens received. For example, as to the 
stigmatie surface, it may or may not be restricted to the extremities of the much-divided 
style-branches. We hope, however, that Mr. White may be able some day to send us 
fresh seeds, and so introduce Begoniella into home cultivation, for which it would be a 
very valuable acquisition.
