…adelphous |
|
architecture |
flower, androecium |
Having two or more distinct sets of stamens, the sets differing from one another in the arrangements, insertions, positions and/or morphologies of the included stamens, the number of sets indicated by the prefix, at least one set with two or more members; as in diadelphous, monadelphous, triadelphous. |
|
style |
|
STRUCTURE |
|
A narrow, usually elongate, ontogenetically distal portion of a simple or compound pistil, overtopping the ovary and bearing one or more stigmas; arising from the summit of the ovary, but sometimes apparently from its base at maturity to ontogenetic displacement from its primordial distal position. In a compound pistil the various simple (carpellary) components of the style(s) may not be connate over their entire lengths; the pistil is then regarded as having a branched style or styles. |
|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
|
infrabracteal |
|
insertion |
|
Upon the axis directly below a bract insertion. |
|
dyadal |
|
arrangement |
pollen |
Cohering and shed in pairs, each tetrad having separated into halves. |
|
funicular |
|
derivation |
aril |
Produced from or a modification of the funiculus (funicle). |
|
caducous |
|
duration |
structure |
Deciduous upon or immediately after emergence, with little or no evident senescence beforehand. |
|
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. |
|
endocarp |
|
STRUCTURE |
|
The innermost tissue layer of a pericarp. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
Having petals unequal in size and/or shape. |
|
monochlamydeous |
|
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 |
|
Constricted in width or breadth at or near the middle of its length. |
|
episepalous |
|
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. |
|
woody-clumping |
|
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. |
|
tetradynamous |
|
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. |
|
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
