INFLORESCENCE.

(Sweet William] ; glomerate, when the axes are almost suppressed, and extremely 

 irregular (Box, fig. 166). 



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

 In the Labiates (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 Composites (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 inflorescence (Heartsease, fig. 170) ; but a little below the 

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

 obvious 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 Jias been called epiphyllous, from the flowers
