Comments to the Table: In principle, as all vegetative (sterile) parts of C. trifida are present underground, no sterile individuals can be counted by this method. However, in some cases very diminutive specimens are found that are at least functionally sterile. Thus, the numbers given in the second row of the table represent such individuals. Also included here are shoots which disappeared prior to flowering. (To see graph, point at ).
