THE FLORAL ENVELOPS, OR PERIANTH. 



463. HYPOGYNOUS (VTTW, under, yvvf), pistil) is an adjective term in 

 frequent use, denoting that the 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- 

 cups are hypogynous. 306

Section of flowers. 304, Jeffersonia diphylla, hypogynous. 305, Viola rotundifolia. 306 

 Phaseolus multiflorus (bean, organs spirally twisted). 307, Pyrus (Pear), perigynous ; ovaries 

 nearly inclosed. 308, Primus (plum) ; ovary not inclosed. 



464. PERIGYNOUS (rapt, around) denotes that the organ is inserted 

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

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

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

 be perigynous. 



465. EPIGYNOUS (e-rrt, 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. 



466. THERE is ALSO ANOTHER SET OP TERMS in use, of the same application, 

 founded upon a more modern view of the floral structure, viz., "calyx adherent," 

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

 location of the receptacle.
