463. Hypogynous (vttu), under, yvvrj, pistil) is an adjective term in 

 frequent use, denoting that tlie organs are inserted into the receptacle 

 under or at the base of the free pistil or 

 ovary. It is, therefore, not applicable to the 

 pistil itself. Thus the outer organs of butter- /-/ajji 

 cups are hypogynous. 806 [||iii|||

 Phaseolas raultiflorus (bean, organs spirally twisted). SOT, Pyrus (Pear), perigynous ; ovarieB 

 nearly iaclosed. 308, Pruniis (plum) ; ovary not inclosed. 



464. Pebibynous {nepi, around) denotes that the organ is inserted 

 on the calyx-tube around the free ovary. Thus in Thlox the stamens 

 are inserted on the tube of the corolla.^^ In cherry both stamens mid 

 petals are (apparently) inserted on the calyx-tube. The calyx can never 

 be perigynous. 



465. Epigtnous (crrl, upon) denotes that all the organs are appa/- 

 rently inserted upon the ovary, as seen in the apple, caraway, sunflower. 

 The common phrases " calyx superior," " ovary inferior," have the same 

 signification as calyx epigynous, all implying the apparent insertion 

 of the organs upon or above the ovary. 



■166. Therk is also another set of terms itt U3e, of the same application, 

 founded upon a mora modern view of the floral structm-e, viz., "calyx adherent," 

 " ovary adherent." Which is the better form of expression vrill depend upon our 

 location of the receptacle.
