THE WEIGHT OF THE EMBRYO 409 



THE WEIGHTS OF EMBRYOS IN ALBUMINOUS RESTING SEEDS continued. 



* Proportions of the embryo of Glaux maritima from figure in Das Pflanzenreich, 

 iv. 237. 



t This represents a mean result for three species of Cassia (fistula, grandis, marginata). 



Here we have the weights of the embryos for about fifty- Remarks on 

 three species and generic types of albuminous seeds, of which 

 almost a third belong to palms. For reasons before implied, the 

 relative weight of the embryo in proportion to the kernel is 

 alone given. This is the only ratio that is generally applic- 

 able, it being apparent that the inclusion of the seed-coats in 

 the discussion would have but little significance in a series 

 comprising the seeds of palms, whilst the proportional weight 

 of the embryo with regard to the fruit would possess but little 

 value, if only for the reason of there being many-seeded as 

 well as single-seeded fruits. 



If required, the proportional weight of the embryo with 

 reference to the entire seed (kernel and coats) can be
