V. Perigyn^. 



Flower displaying a tendency towards the perigynous structure. An annular body 

 is elevated from the floral axis bearing the perianth and the stamens, and enveloping 

 the gynaeceum as a cup-, saucer-, or urn-like receptacle ; or it becomes adherent in its 

 growth to the carpels (B, Order 2, Family 2). In a few families which are placed here 

 provisionally (B, Order 3, Families 4-6) the ovary is truly inferior. 



A. Calyciflora. Perianth simple, either sepaloid or petaloid and usually tetra- 

 merous ; the tubular receptacle is generally of the same nature, and in Family 3 is 

 even quadripartite, corresponding to the four perianth-leaves and to the four stamens 

 superposed on them (see Fig. 339, p. 478); stamens fewer than, as many as, or 

 twice as many as the perianth-leaves; ovary monocarpcllary, rarely bilocular, with 

 one or a few seeds ; seed with little or no endosperm. 



Order 1. ThymelsBinesB. 

 Families: i. Thymelaeaceae, 



2. Elaeagnaceae, 



3. Proteaceae. 



B. CoroUiJlorcB. Calyx, corolla, and androecium placed on a flat (Order i) or 

 cup-shaped receptacle, or on one hollowed out into a deep urn-shape (Order 2 and 

 in part 3), which is often (Order 2) thick and succulent (as in the apple, rose-hip, 

 &c.); sepals distinct or coherent (Order i;); petals always distinct (corolla dialy- 

 petalous) ; the two perianth-whorls usually pentamerous, sometimes tetramerous ; 

 stamens as many as or twice as many as (Order i) sepals and petals, or a much 

 larger number (Order 2), in Order 3, Family 3, commonly branched; gynaeceum 

 composed of one (Order i, and in part 3) or several or a large number of mono- 

 carpellary ovaries; or (in Order 3) ovary polycarpellary, and sometimes inferior 

 (Families 4-6).
