of none at all. Various parts of subserrate leaves may be entire. 
I could have counted teeth and reached a quantitative expression of 
the serrateness of some leaves, but the entire parts of leaves and the 
great difference in the teeth made such data rather meaningless. 
As the lower surface is described, the majority again of course occu- 
pies the broad middle ground, but there is no tendency toward any 
particular part of it. 
These specimens were all collected in the vicinity of Woodside 
(a post-office a few miles from Palo Alto), which avoided the chance 
of extending the apparent range of variation by introducing geographt- 
cal varieties. Selection of extremes in any direction was also avoided, 
by such devices as choosing a bush at too long range to more than
