406 PHYSIOLOGY AT THE FARM. 



Gesneracece, Gesnera order. Natives chiefly of the warm 

 regions of America. The succulent fruits are occasionally 

 edible. 



CordicKece, Sebesten order. The drupes of Cordia Myxa 

 and C. latifolia are called sebesten plums, and are used as food. 



Boraginacece, Borage order. The leaves of borage were 

 formerly employed in cookery or as salads, the flowers in cup 

 and cool tankards. Mertensia maritima, a sea-shore plant, 

 has leaves which taste like oysters. Sympliytum asperrimum, 

 a native of the Caucasus, has been cultivated in Britain as 

 forage. It is particularly nourishing to pigs. 



Solanacece, Potato order. Capsicum, the genus from which 

 the red peppers come. Lycopersicum esculentum affords the 

 tomato or love-apple for sauces. Physalis Peruviana yields 

 the edible Peruvian winter cherry. Puneeria coagulans, 

 the Puneer plant of Khorassan, to coagulate milk and make 

 cheese. 



Solatium tuberosum, potato. The agriculture of the potato 

 does not fall within our plan. It will be enough to indicate 

 its fitness for the food of man and the farm animals by refer- 

 ence to its chemical composition.
