irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
panicle |
|
nominative |
inflorescence |
A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |
carinal |
|
aestivation |
|
Having the petals of the keel (carina) enclosing the others. |
herbaceous 2 |
|
texture |
|
Composed entirely of relatively soft, non-woody (unlignified) tissues derived from primary growth. |
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
amplexicaul |
|
architecture |
foliaceous structure |
See amplexicaulous. |
reticulodromous |
|
venation |
|
Having a single median primary vein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, branching repeatedly, becoming less distinct, and yielding a dense higher-order reticulum near the margin. |
limb 1 |
|
STRUCTURE |
|
A relatively broad portion of a syntepalous (gamotepalous) perianth, synsepalous (gamosepalous) calyx, or sympetalous (gamopetalous) corolla distal to a narrower tube, spreading outward or ascending from the tube, comprising the distinct or connate distal portions of the tepals, sepals, or petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
excurrent |
|
architecture |
axis, laminar vein |
Branching laterally such that the initial axis retains its prominence over the length of the structure, the succesive orders of branches relatively smaller. See also deliquescent. |
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. |
barb 2 |
|
STRUCTURE |
|
A trichome terminated by one or two small, relatively short, stiff, sharp, acutely reflexed appendages. |
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. |
epichilium |
|
STRUCTURE |
|
The distal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also hypochilium, mesochilium. |
continuous 1 |
|
architecture |
inflorescence |
Having the flowers or branch units distributed evenly along the axis, with no significant interruption. |
infrafoliar |
|
insertion |
|
Upon the stem directly below a leaf insertion. |
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
actinocytic |
|
architecture |
stomate |
Having several subsidiary cells oriented radially to its center. |
peltate |
|
architecture |
foliaceous structure |
Petiolate with the petiole attached to the abaxial face of the blade at some point within the margin and otherwise free from the blade. |
samara |
|
nominative |
fruit |
Dry, indehiscent and having one or more integral alate portions that aid in aerial dispersal. |
thyrse |
|
nominative |
inflorescence |
An elongate, indeterminate main axis bearing numerous lateral branches, each the principal axis of a cymose subdivision. |
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
mesochilium |
|
STRUCTURE |
|
The central portion of a labellum (lip) that has distinct proximal, distal, and central parts; in Orchidaceae. See also epichilium, hypochilium. |
strict |
|
course |
|
Lacking any curve or bend. |
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |
