' Except where otherwise mentioned the plants selected for measurement are normal and fairly representative of the 

 subspecies to which they are assigned. The figure given is the average of a number of measurements, but the fluctuation 

 usually is slight on any given plant. In the case of involucres and corollas only the larger ones were measured, on the as- 

 sumption that the smaller ones were not fully developed. ' Minor variation 17.
