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. Calycifloroe, 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. ThymelaBineae. 
Families: i. Thymelaeaceae, 
2. Elaeagnaceae, 
3. Proteacese. 
B. CoroUiflorcs. Calyx, corolla, and andrcecium placed on a flat (Order r)-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).
