upon all of them. The pods when fresh were very large, often con¬ 
taining eight or nine seeds and being moreover particularly wide ; 
when dry they were deeply constricted between the seeds and had a 
very shrivelled appearance, the parchment layer being quite wanting. 
The first flower appeared upon the plants about 56 days after

B .—The Cross-bred Forms. 
1. Native pea No. 1 x French sugar pea .—From 18 pollinations 
there resulted 6 pods which were gathered on January 30th, 1903. 
They contained 26 seeds which exactly resembled those produced 
upon the same plants by self-fertilization. The average longest 
diameter of these seeds was 6-4 mm., which is almost exactly equal 
to the mean length of a sample of over 2,000 seeds of No. 1 which 
were accurately measured for another purpose. 
Sixteen of these seeds were sown on May 2, and all of them 
germinated. The following table shows some of the characters of 14 
plants which were taken up on July 30 :—
