Floral (cf. also under Flower) diagram (cf. those given here under 

 many fams.), an imaginary section through the bud, showing the 

 arrangement of parts, aestivation, &c. ; it may also be used (cf. Poly- 

 gonaceae) to express theoretical views as to multiplication or sup- 

 pression of organs. At the top is the original stem upon which the 

 fl. is a branch, and at bottom the bract; lat. are the bracteoles ; 

 then follow K, C, A, and G, showing their relative positions to one 

 another and lo the br. When free they are shown separate; when 

 concrescent, they are joined by lines ; the anthers show the mode of 

 opening, the ovary the placentation, stigmas, &c. ; -envelope, the 

 perianth ; -formula, a convenient way of showing many features of 

 a fl., largely used here. K 3, C 3, A 3, G 3, means calyx of 3 free 

 sepals, co_rolla of 3 free petals, &c.; ovary superior. K (3), C (3), 

 A 3 + 3> G (3), means calyx (corolla) of 3 concrescent sepals (petals), 

 stamens in two whorls of 3 each, free, ovary of 3 concrescent carpels, 

 inferior, and so on ; -kingdoms, see Floral Regions ; -leaves, the 

 parts of the fl., esp. K and C ; -mechanisms, mechanism* to contrive 

 as far as possible cross-fertilisation for a fl., and to ensure that the 

 visiting insect shall receive pollen or touch the stigma, or to ensure 

 self-fertilisation. They may be classed as follows (see individual 

 headings for examples): Anemophily, see Pollination by Wind; 

 Cleistogamy (production of self-fertilising fl.) ; Dichogamy (ripening 

 of cf and ? at different times, with or without movements of sta. 

 and style); Dioecism and other sex-distributions (q.v.)\ Explosive 

 mechanisms ; Heterostylism ; Loose-pollen mechanisms ; Piston- 

 mechanisms; Pollen-prepotency \ Pollination by Animals; Pollination 

 by Water ; Pollination by Wind ; Self-sterility ; Sensitive stamens ; 

 Sensitive stigmas ; Special mechanisms, such as Asclepiadaceae, Ficus, 

 Orchidaceae, Salvia, Yucca, &c. ; Style-projection; Trap Flowers, &c.
