MORPHOLOGY OF THE SEED 167 



II. The Anatomy and Morphology of the Seed 



4. a. Study the outside of the Horse-chestnut (a typical 



specimen), and minutely observe : - 



What is its shape, its color, and its 



markings ? 



Does it show any feature not in the Beans ? 

 Answer, as before, by drawings and notes. Select 



for yourself the best scale. 



b. Remove the coatings from a soaked seed, and 

 observe : 



(1) How many coats are there, and how 



are the markings related to struc- 

 tures inside ? 



(2) What shapes have the internal parts, 



and how are they connected with 

 one another ? 



(3) Are there any new parts or features 



not present in those already studied ? 

 Answer, as before, by drawings and notes. Care- 

 fully separate with the fingers all parts that 

 can be forced apart without tearing. 



5. In a similar way study the seed of the Morning- 



glory. 



6. In a similar way study the grains of Corn. 



Where parts cling too closely to be separated by 

 the fingers, use a knife, and try clean median 

 sections.
