4i 4 Cutting. — Observations on Variations in the 
styles and stigmas were well developed except in a few forms in which the 
style reached only to the mouth of the tube.

A number of forms (Fig. 4 , a) were also found with short, wide corolla 
tubes, short filaments, abortive pollen, as far as could be found out from 
the alcohol material, and styles which were commonly held in the lower 
lip and had the stigmas dipping into pollen which had possibly dropped 
from the anthers into the depression in the lower lip. No evidence was 
found to show whether this self-pollination was effective or not. If all the 
pollen of the flowers was abortive it could of course have no effect, but if 
some of it was capable of germination and of pollinating other flowers, 
there could be no a priori reason against its being effective on the pistil of 
the flower to which it belonged, for Knuth (23) reports self-pollination as 
usual in the ordinary flowers of this species. 
Similar flowers to these (and certainly not fertile) were formed in the 
summer in large quantities in plants that were obviously diseased, as they
