64 THE STORY OF PLANT LIFE 



indefinite series. There is usually a calyx and 

 corolla. The stamens are inserted on the recep- 

 tacle and hypogynous, being below and free from 

 the ovary and calyx, or on a short or long stem or 

 upon a disc at the extremity of the flower-stalk. 

 The ovary is superior; the stamens are, therefore, 

 inferior. 



In this group are included some forms in which 

 the stamens are apparently perigynous or epigynous, 

 as in Nymphcea, and in some Caryophyllaceae. 



The ovary is apocarpous with one or more carpels, 

 with the ovules sutural or basal in Ranunculaceae 

 and Berberidaceae. 



The ovary is syncarpous, i- or more celled, in 

 Nymphaeaceae, Papaveracese, Fumariaceae, Cruciferae, 

 Resedaceae, Cistaceas, Violaceae, Caryophyllaceae, 

 Portulaceae, Tamaricaceae, Polygalaceae, Elatinaceae, 

 Hypericaceae, Malvaceae, Tiliaceae, Linaceae, Gera- 

 niaceae, Ilicaceae, Empetraceae. 



Aquifoliaceae or Ilicaceae are sometimes included 

 in Calyciflorae. Droseraceae are included in Thala- 

 miflorae. Empetraceae are included in Apetalae, 

 amongst which Illecebraceae are often ranked near 

 Caryophyllaceae. The Portulaceae are placed in 

 Calyciflorae by some authorities, and Paronychiaceae 

 are included in Illecebraceae amongst Mono- 

 chlamydeae, but are by some included next the former 

 in Calyciflorae. 



Balsaminaceae and Oxalidacese are sometimes 

 included in Geraniaceae.
