===Phyllotaxis=== As with [[leaf|leaves]], flowers can be arranged on the stem according to many different patterns. See '[[Phyllotaxis]]' for in-depth descriptions. <gallery> Image:Inflorescences Raceme Kwiatostan Grono.svg|Alternate flowers Image:Traube dekussiert (inflorescence).svg|Opposite flowers </gallery> Similarly arrangement of leaf in bud is called Ptyxis. When a single or a cluster of flower(s) is located at the axil of a bract, the location of the bract in relation to the stem holding the flower(s) is indicated by the use of different terms and may be a useful diagnostic indicator. Typical placement of bracts include: * Some plants have bracts that subtend the inflorescence, where the flowers are on branched stalks; the bracts are not connected to the stalks holding the flowers, but are [[adnation|adnate]] or attached to the main stem (Adnate describes the fusing together of different unrelated parts. When the parts fused together are the same, they are connately joined.) * Other plants have the bracts subtend the [[pedicel (botany)|pedicel]] or peduncle of single flowers. Metatopic placement of bracts include: * When the bract is attached to the stem holding the flower (the pedicel or peduncle), it is said to be '''recaulescent'''; sometimes these bracts or bracteoles are highly modified and appear to be appendages of the flower calyx. Recaulescences is the fusion of the subtending leaf with the stem holding the bud or the bud itself,<ref>Kubitzki, Klaus, and Clemens Bayer. 2002. ''Flowering plants, Dicotyledons: Malvales, Capparales, and non-betalain Caryophyllales. The Families and genera of vascular plants, 5.'' Berlin: Springer. p. 77</ref> thus the leaf or bract is adnate to the stem of flower. * When the formation of the bud is shifted up the stem distinctly above the subtending leaf, it is described as '''concaulescent'''. <gallery> Image:Bluete und Tragblatt (inflorescence).svg|Flower and subtending bract Image:Türkenbund dunkel.jpg|''[[Lilium martagon]]'' (flower and subtending bract) Image:Konkauleszenz (inflorescence).svg|Concaulescence Image:Tomato scanned.jpg|''[[Tomato|Solanum lycopersicum]]'' (concaulescence) Image:Rekauleszenz (inflorescence).svg|Recaulescence Image:Tilia cordata Owoce lipy 656.jpg|''[[Tilia cordata]]'' (recaulescence) </gallery>
