186 FLOWER. 



When the Corolla is inserted into the receptacle be- 

 neath the germen, as in Foxglove and Stramonium, it is 

 termed hypogynous. When it is inserted into the calyx 

 and surrounds the germen, as in the Currant, it is 

 termed perigynous, and when it is inserted upon the 

 germen, as in the Trumpet honeysuckle, it is termed 

 epigynous. 



The stamens are hypogynous as in the Poppy and 

 Tulip tree ; perigynous as in the Currant and Rose ; 

 and epigynous as in Sassaparilla and in the umbellifer- 

 ous plants. When they arise from the corolla they 

 are said to be epipetalous. 



A flower furnished with both calyx and corolla is 

 said to be complete ; destitute of a calyx it is said to be 

 naked ; and without a corolla it is apetalous or incom- 

 plete. When the stamens and pistils both occur ia 

 one flower it is perfect or united ; when they occur 

 only in different flowers of the same species as in the 

 Indian Corn, the flowers are separated or diclinious, 

 that which bears the stamens being unfertile or barren 

 and that with pistils being fertile and bearing the seed. 

 When barren and fertile flowers both occur on the 

 same plant, they are said to be monoecious, if they grow 

 on two separate plants as in the Poplar they are dioe- 

 cious ; but when united and separated flowers occur in 

 the same species M making a sort of compound house- 

 hold," they are said to be polygamous. 



A compound flower has numerous sessile florets sit- 

 uated on a common receptacle and enclosed in a com- 

 mon calyx. These florets are monopetalous and su- 

 perior, each standing on the germen or seed, and usual- 

 ly five cleft at the summit. They enclose five stamens 

 whose anthers are united into a cylinder, and hence the 

 compound flowers are usually termed Syngenesious,
