I, H. Burkill — Flower of Ranunculus arvensis. 



115 



(iij — At 23 the stamens are a little above what would seem 

 reasonable, the carpels below. 

 I do not intend to attempt any explanation of these facts, but I 

 must observe that if we cut out of our figures all flowers which have both 

 their sepals and their petals other than five in number, the irregulari- 

 ties jusfc noted almost disappear: and thej do not disappear if we cut 

 out only those flowers with sepals other than five: and this indicates 

 that between 15 and 20 the stamens are able to add to their number 

 from the petals. This is done in table XXVII.
