The present plant is very near D. scabra Tuuns. and D. pulchra 
VipaL; but it differs from the former in having dentate stamens 
and in the number of styles which are usually five; and from the 
latter, in having quite obtuse leaves. In Vipat’s plant, the leaves 
are usually more acuminate, and very acute at the apex. Deutzia 
crenata 8. et Z. 9. Taiwanensis Maxm. cited above may possibly 
be identical with this plant, though I have found some different 
points between the description of Maxrtmowicz and that of the 
present one; for the Deutzia credited in Formosa by Maxrmmowicz, 
so far as is considered from the locality given by him, may not 
be otherwise than this plant as it is the only one to be found in 
the lowland of Formosa. Maxrmowicz’s plant is not near D. crenata 
S. et Z., nor is it referable to a variety of that species; but it must 
be a quite different one, so far as the diagnosis is concerned.
