cotyledons, are the internal substances which constitute 

 the bulk of the seed; and the heart, or embryo, is that 

 small part, which is the first principle of a new plant and 

 is commonly situated between the cotyledons. 



To obtain a practical knowledge of these parts, yon should take a 

 common bean, as the most easy for illustration. On examining this 

 seed whole, you will perceive the part by which it was attached to 

 the seed-vessel, by the scar, therefore that part is called the eye; in 

 the second place, you must take off the husk, above denominated as 

 the seed-coat ; which done, the remaining part, you will observe, 

 easily divides into two equal parts of considerable size, called the 

 seed-lobts ; and, situated between these lobes, you will find a small 

 peck or seed called the embryo.

37. The receptacle is the seat or base upon which the 

 different parts of the flower are situated. 



The receptacle is not always distinguishable by any particular 

 figure, except in compound flowers, in which it is very remarkable 

 and important. (F. 9.) If you select, for example, the sun-flower, 

 and detach the calyx, corolla, and florets, you will have a complete 

 base or receptacle In the daisy you will find the receptacle conical ; 

 in the chrysanthemum, convex ; and in others, flat, and so on.
