1 No. 259 should perhaps have been noted on a slightly earlier date. 
The letters L and E in Table II show (as above stated) the 
broad relations between the dates of 1920 and those of 1917, 1918 
and 1919. The letter L means’that the species so marked flowered 
later than in 1920; in the same way E indicates earlier flowering. 
What is at once obvious is that the 1917 dates are universally 
later than the corresponding entries for 1920. The same thing is, 
roughly, true of 1919, there being only three cases in the first 100 
which are earlier than 1920, and one plant flowered on the same 
day in 1919 and 1920. In 1918 the case is different. Taking the 
same material, viz. No. 7 to No. 107, we have: 
March 3-April n 
12 E 
11 L 
April 13-May 13 
iE 
21 L 
2 equal 
May 14-May 27 
8 E 
18 L 
2 equal 
The sums are... 
21 E 
50 L 
4 equal 
We see that the cases in which the spring flowers of 1918 
(March 3-May 27) were earlier than those of 1920 are 21 in number: 
the cases in which 1918 is later being 50; there are also four cases
