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. |
|
dyad |

STRUCTURE |
|
A pair of coherent pollen grains shed as a unit. |

|
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
|
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
|

STRUCTURE |
|
The innermost tissue layer of a pericarp. |
|

architecture |
flower, perianth, corolla |

architecture |
flower |
Having a monocyclic perianth. |
|
reduced |
|
size |
|
Unusually or unexpectedly small. |
|
supramedial |
|
insertion |
|
Just above the middle of the structure in point. |
|
waisted |
|
solid shape |
|

|
insertion |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
|
apocarpous |
|
architecture |
flower, gynoecium |
Having two or more simple pistils (carpels). |
|
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
|
caudex pl. caudices |
|
STRUCTURE |
|
The short, persistent, thickened, more or less erect, main stem of a perennial plant that otherwise has annual stems. |
|

|
habit |
plant |
Having or developing the character of a woody clump. See also arboreous, arborescent, bushy, frutescent, fruticose, shrubby, subshrubby, suffrutescent, suffruticose, tree-like. |
|
extent |
|
CHARACTER |
|
Reach of the septum or septa within the ovary or fruit, relative to the ovary wall or pericarp and its center. |
|

|
architecture |
flower, androecium |
Diadelphous with four stamens in one set and two in the other. See also didynamous. |
|
cyathium pl. cyathia |
|
nominative |
inflorescence |
Resembling a single flower, the unbranched axis very short with a terminal pistillate flower and several lateral staminate flowers, the whole subtended and to some degree enclosed by a cupulate envelope of bracts, the flowers diminutive and presumed to be evolutionarily reduced; characteristic of Euphorbia. |
