^ The ovary is described as 5-locular : I do not find it so, but certainly 

 -;- and also 3-locular in tlie few flowers at my disposal for analysis. 

 ■Ine changes in the placenta, its division and complex lamination in 

 more advanced stages make it very difficult to understand or describe 

 intelhgibly without adequate material. I do not find the ridges on 

 tfte ovary, conspicuous in the flowering stage, but obsolete later, to 

 correspond very definitely with its internal arrangements. The in- 

 equality in size of the leaves in at least some, possibly in all, of the 

 pairs was first noted by Miss Smith in preparing her drawing for our 

 nograph. — D. Oliver.
