species is described as decidedly exogenous, possessing pith and 
vascular wedges, traversed by medullary rays. In some species 
the central tissue is formed of long 4 wood-tubes.’ Special modi¬

XXIII.— On the Existence of two forms of Peloria. By 
Maxwell T. Masters, M.D., F.L.S., Lecturer on Botany, St. 
George’s Hospital. 
In collecting materials to illustrate the nature of Peloria, I have 
been much struck with the fact of the existence of two varieties of 
this exception to the ordinary rule of floral structure, and the more 
so, as this duality is almost entirely unnoticed by systematic writers 
on this subject.
