232 PASTORAL AND AGRICULTURAL BOTANY 



Quince (Cydonia oblonga). The quince tree produces a fruit hairy 

 when young, becoming smoother with age. The skin is yellow at matu- 

 rity and the seeds are surrounded by a mucilaginous covering. 



Plum (Prunus). This genus includes a number of species of trees 

 which yield a plum-like fruit. 



Sweet Cherry (Prunus avium). The sweet cherry is produced on a 

 tall European tree, which has been cultivated in America for many years. 



Sour Cherry (Prunus cerasus). The tree which produces the sour 

 cherry is smaller than the sweet cherry tree, but like it it is a native of 

 Europe. 



Apricot (Prunus armeniaca). This species is considered to be a native 

 of southern Asia. 



Peach (Prunus persica). The peach tree is probably a native of 

 China and was long ago introduced into Europe and later America through 

 central Asia. 



Almond (Prunus amygdalus). The almond is cultivated for its kernel 

 with seed, therefore the outer fruit coats are fibrous and not fleshy as in 

 the peach with which the alrnond is closely related. 



Olive (Olea europaa). The olive tree with evergreen, grayish-green 

 foliage is a native of the Mediterranean region, 'where it has been culti- 

 vated since ancient times. 



Ash Pumpkin (Benincasa cerifera). A large, handsome, oval-shaped 

 gourd grown throughout China and Japan. 



Water-melon (Citrullus vulgaris). This fruit because of its refrigerant 

 pulp is deservedly popular in late summer. 



Melon (Cucumis meld). 



Native Cucumber (Cucumis sativus). The fruit is usually peeled, 

 sliced and served in vinegar. 



Pumpkin (Cucurbita pepo). The fruit of this annual species has a 

 ribbed usually reddish-orange rind. A 



Squash (Cucurbilia maxima). There are several kinds of squashes, 

 such as the turban, Hubbard, Marblehead and marrow squashes. 



Cantaloupe (Cucumis melo). The true cantaloupes are usually deep- 

 ribbed, hard-rinded and warty, or scaly. 



Tomato (Lycopersicum esculenlum). The fruit of this short-lived 

 perennial of the family Solanacea used to be considered poisonous and was 

 known then as love-apple. It is now one of our most important fruit 

 vegetables.
