 relation to the number of styles. 



329. The husk -tomato or ground- cherry (one 

 kind is known as strawberry -tomato) is shown in 

 Fig. 277. The flower, with its 

 calyx a half smaller than the 

 corolla, is at 8. The pistil is 

 2-loculed, and ripens into a 

 true berry, very like a small 

 tomato. The 

 calyx, however, 

 grows enor- 

 mously (Nos. 

 9, 10). It is 

 evident that 

 the part which 

 chiefly enlarges 

 is the tube and not the lobes. In the cockle and 

 the husk -tomato, the calyx is not considered to 

 be part of the fruit, because it is not organ- 

 ically united with the capsule or the berry, but 

 merely encloses it. 



329a. Seeds of three or four kinds of husk-tomato (or physalis) 

 are sold by seedsmen, and the plants are easy to grow. Some of 

 them are grown for the brilliant color of the great inflated calyx, 

 and others foi the edible berries. 



330. The agrimony is a rather small herb of 

 rich woods and tangles, bearing small yellow flow-
