STRUCTURE |
|
The basic architectural unit of the flower-producing portion of a plant; comprising one or more flowers, their associated supporting axes (peduncles, main axes, branches and pedicels), if any, and the appendages thereto (bracts, bractlets or bracteoles or prophylls, involucres, involucels, and glumes), if any; delimited by the insertion or gradation of a single peduncle, peduncle cluster, pedicel, pedicel cluster, or sessile flower, as the case may be, directly upon or into some proximal vegetative structure not of one of these types; depending upon the type(s) of flowers included, may be bisexual (all flowers bisexual), staminate (all flowers staminate), pistillate (all flowers pistillate), sterile (all flowers sterile), or mixed (two or more types of flowers present); most appropriately described using nominative terms. |
