Mixed inflorescences are those in which the definite and indefinite both appear. 

 In the Labiatw {Lamium, fig. 167) the general inflorescence is indefinite, while

the separate heads are true axillary cymes or fascicles. In the Mallows the same 

 arrangement occurs (fig. 168). In Compositw {Groundsel, fig. 169) the general 

 inflorescence is a definite corymb, and the separate portions are heads. The definite 

 inflorescence is sometimes reduced to a single flower, and resembles the one-flowered 

 pedicels of an indefinite infiorescence {Heartsease, fig. 170) ; but a little below the 

 flower two small bracts {bracteoles) will be found, in the axils of which are two 

 obyious or suppressed shoots, which sometimes flower {Bindweed, fig. 171). The 

 two bracteoles of a one-flowered pedicel are therefore the evidences of a two- or three- 

 flowered cyme, of which the primary axis only is developed. 



The inflorescence of certain plants has been called epiphyllous, from the flowers
