Comments to the Table: With L. ovata living in colonies and with a single plant having the ability to produce more than one stem, it is obviously impossible to count the number of individuals by the method described. Therefore, the figures in the table are the recorded number of stems. (To see graph, point at ).
A ' ? ' indicates that no registration was done in the year in question.
