HAZEL NUTS

The seedling was washed clear of soil and sketched. 



There was merely a split in the 

 seed-coat to accommodate the collar 

 and it is worthy of observation that 

 this protrudes farther from the seed 

 than the collar of the Acorn ; the 

 radicle and plumule being rather 

 more than l/l6th-inch from the seed; 

 those of the Acorn are always close 

 up. 



Cut in section along the line of the 

 spht in the seed coat it was seen that 

 the collar was not adherent to both 

 halves — as in the Acorn — but emerged 

 whole from the apex of the seed.

The following is a sketch of the seedling, and seed cut

At the Meeting of The 

 British Association at 

 Bournemouth in September, 

 1919, I found occasion to 

 mention the want of uni- 

 formity in germination and 

 growth common to all seeds 

 and expressed the opinion 

 that it was due to inequality 

 in the matter of develop- 

 ment of the embryo at the 

 time of sowing ; instancing 

 trials of Hazel Nuts which 

 although potted on the same 

 day varied as long as 

 several months in germina- 

 tion.
