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. Calycijlorm. 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. 370) ; stamens fewer than, as many as, or twice as 

 many as the perianth-leaves ; ovary monocarpellary, rarely bilocular, with one or a 

 few seeds ; seed with little or no endosperm. 



Order 1. ThymelsBineaB. 

 Families: i. Thymelaeaceae, 



2. Elaeagnaceae, 



3. Proteaceae. 



B. CorolliJiorcE . 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 2) or several or a large number of mono- 

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

 (Families 4-6).
