one of the sepals as long as the petals. The most curious variation 
found, was one in which the place of the third sepal was taken by 
an irregularly shaped foliage leaf. 
The following tables which deal only with the ascertained number 
of sepals and petals in 2116 cases, show some interesting results : —
