CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |
involucrate 2 |
|
architecture |
capitulum (head) |
Having an involucre. |
circular |
|
arrangement |
bundle scars |
Forming a circle. |
tetrad |
|
STRUCTURE |
|
A group of four pollen grains originating from a single pollen mother cell. |
obturbinate |
|
solid shape |
|
Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
trioecious |
|
reproduction |
taxon |
Having some flowers or spikelets functionally unisexual and some bisexual, some plants having only staminate or only pistillate types, other plants having only bisexual types. |
galea pl. galeae, galeas |
|
STRUCTURE |
|
A galeate (galeiform, helmet-shaped) sepal or petal in a zygomorphic calyx or corolla, differing markedly in shape from and sometimes partially enclosing the other sepals or petals. |
enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
rhipidiate |
|
architecture |
inflorescence |
Comprising one or more rhipidia. |
stipel |
|
STRUCTURE |
|
A stipular analogue subtending a leaflet. |
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
reduced |
|
size |
|
Unusually or unexpectedly small. |
staminodial |
|
insertion |
|
Upon or otherwise directly associated with the staminodes. |
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. |
valve |
|
STRUCTURE |
|
Any longitudinal segment of a fruit wall delimited by lines of dehiscence. |
vascular |
|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
abortive |
|
maturation |
spore, pollen, seed |
Never attaining functional maturity due to defective or arrested development. |
sinuous |
|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
decompound |
|
architecture |
|
Comprising two or more orders of equivalent substructural entities; multiply compound. |
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
andromonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and staminate ones. |
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
branchlet |
|
STRUCTURE |
|
A branch of the highest or ultimate order. |
synanthous |
|
maturation |
non-floral structure |
Maturing at the same time as the flowers. See also coetaneous. |
