prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in monandrous, monocolpate, monocyclic. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |

plant |
Normally reproducing sexually only once, then promptly senescent. |
|

monochasium pl. monochasia |
|
nominative |
inflorescence |
Determinate and falsely dichotomous with each axial segment bearing a single, sessile terminal flower; presumably derived from a dichasium by loss of the lateral flowers. See also cincinnus, cyme, cymule, dichasium, helicoid cyme, scorpioid cyme. |

Having all flowers or spikelets functionally unisexual, and all plants having both staminate and pistillate types. See also dioecious. |
|
