74 GERMINATION 



that I could not determine the length of the radicle, but the 

 seedling was unusually interesting from the fact that a 

 plumule and radicle had grown from each half of the seed, 

 while the seed itself had not suffered any diminution of size. 



As will be seen from the drawings, each half of the seed 

 had subdivided itself into two ; the radicle and plumule 

 being attached to a quarter instead of to half a seed, but 

 in exactly the same way that I have previously described. 

 The larger plumule bore nine leaves and the smaller, which 

 was red in colour, leaf buds only. Although, measured 

 from the upper surface of the seed, the first was only 4-inches 

 in height, it exhibited a distinctly hard, woody and vigorous 

 radicle and its seed substance was almost normal ; that of 

 the second being darker in hue. The following sketch is 

 of the seedling before removal of the seed coat. 



To all appearance the above drawing would seem to be 

 two seedlings growing from one seed but when the seed 

 coat was dissected away the seedlings — not being in any 

 way connected — fell apart, and were drawn^in their relative 

 positions.
