SEED-NUMBER AND FRUIT-SIZE 



335 



B. — Table comparing the Relation between the Number of 

 Seeds and the Weight of the Entire Fruit and its Parts 

 IN the Moist and Dry Condition for the Legumes of 

 Leuc^na glauca and Albizzia Lebbek. 



The shrinking ratios employed for Leucana glauca are 100 - 22 for the pericarp, and 

 100 - 40 for the seeds; the pericarp thus losing 78 per cent, of its weight in the drying 

 process, and the seeds 60 per cent. 



The ratios used for Albizzia Lebbek are 100-25 fo"^ the pericarp, and 100-60 for 

 the seeds. 



estimated, as I had no opportunity of experimenting on the 

 living fruits. On the average, in moist mature leguines of 

 this character the pericarp loses about 75 per cent, of its weight 

 during the drying process, whilst the weight of the seeds is 

 diminished by about 60 per cent. ; and these are the ratios 

 applied to the dry Albizzia pods. The estimate for the moist 

 fruit thus obtained cannot be far wrong, and since any error 

 would uniformly aiFect all the results, the relations between 

 them would be unaffected.
