|
spike |
|
nominative |
inflorescence |
An elongate, determinate or usually indeterminate axis bearing sessile flowers inserted singly along it, unbranched or sometimes bearing lateral branches of the same nature. |
|
incumbent 2 |
|
orientation |
anther |
Oppositely parallel to the filament on the adaxial side of the latter. |
|
stilt root |
|
STRUCTURE |
|
A relatively stout or strong adventitious root arising from a woody stem branch and extending downward directly toward the substrate, within which it ultimately becomes anchored, thus supporting the branch of origin; as in some Ficus (Moraceae). |
|
course |
|
CHARACTER |
|
Linear pattern of the centerline through the length of an axis or vein. |
|
collar 2 |
|
FEATURE |
|
The junction between the sheath and blade of a leaf; esp. in Poaceae (Gramineae). |
|
isopetalous |
|
architecture |
flower, perianth, corolla |
Having the petals essentially alike in size and shape. |
|
anthelate |
|
architecture |
inflorescence |
Comprising one or more anthelae; esp. in Juncaceae. |
|
striped |
|
coloration |
|
Having one or more elongate, relatively narrow and, when multiple, more or less parallel, areas of contrasting hue and/or intensity. |
|
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
synandrous |
|
architecture |
flower, androecium |
Having the stamens connate. |
|
superposed 2 |
|
position |
buds |
Axillary in pairs, one member of each pair directly above the other. |
|
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
|
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
|
thyrsate |
|
architecture |
inflorescence |
Comprising one or more thyrses. |
|
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
|
prickle |
|
STRUCTURE |
|
Any unvascularized spine-like enation originating in the epidermis, cortex, or mesophyll of any shoot part. See also spine, thorn. |
|
fistulose |
|
solid shape |
|
Basically tubular with closed ends. |
|
perforate |
|
architecture |
foliaceous structure |
Having portions of the laminar (blade) area naturally devoid of any tissue. |
|
floret |
|
STRUCTURE |
|
A very small, structurally specialized flower, especially when occurring in capitulum (head; Asteraceae), or in a spikelet (Poaceae), where it includes the immediately subtending bracts (lemma and palea). |
|
dimidiate |
|
plane shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
|
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
|
embryo |
|
STRUCTURE |
|
The rudimentary spermatophyte contained within a viable seed. |
|
acrocaulous |
|
position |
|
At or very near the stem tip. |
|
dwarfed |
|
size |
plant |
Strongly reduced; unusually or unexpectedly very small throughout. |
