I. H. Bui-kill — Flower of Ranunculus arvensis.

(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 fclian five in number, the irregulari- 

 ties just noted almost disappear: and they 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.

 different moods in flowers of various numbers of parts.
