 stamens arise from the thalamos (the old name for 

 the floral receptacle, as the extremity of the flower- 

 stalk, or pedicel, is now called), and are polypetalous, 

 i.e. with all the petals separate or free. The petals 

 and stamens are lii/pogynovs, or " under the ovary," 

 arising directly out of the receptacle.

 or a thick ring or disc (from the Latin discus, a " quoit "), 

 as in Bar OS ma. 



Division III. Ccdyciflora\ — The corolla is poly- 

 petalous as in the two previous divisions, but now 

 stands on the edge of a receptacular tuhe} This con- 

 sists of an outgrowth from the receptacle below the 

 pistil. It is sometimes dish-like, as in strawberry and

 it forms a characteristic feature. See above, p. 52.
