tomentose |
|
pubescence |
|
Bearing dense, short, stiff, capillate trichomes. See also tomentulose. |
|
decumbent |
|
habit |
axis |
Reclining upon the substrate proximally, ascending to erect distally. |
|
cladodromous |
|
venation |
|
Having a single median primary vein that branches to either side along its length, the secondary veins running thence toward the margin, but freely ramifying and becoming indistinct before reaching it. |
|
limb 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae). |
|
prickly |
|
architecture |
|
Bearing prickles. |
|
barbed 1 |
|
apex |
|
Terminated by a small, relatively stiff, acutely reflexed, hook-like structure. |
|
trigamous |
|
reproduction |
inflorescence |
Bearing flowers of three differing sexual constitutions; esp. in Asteraceae (Compositae). |
|
palate |
|
STRUCTURE |
|
The lower, prominent labium (lip) of a personate (gaping, ringent) corolla. |
|
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
|
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). |
|
bract 2 (strict sense) |
|
STRUCTURE |
|
Any primary or first-order lateral structure ontogenetically and anatomically analogous with, and therefore presumably homologous with, but relatively smaller than, a leaf, especially when subtending an inflorescence, other reproductive structure, or portion thereof; putatively, an evolutionarily reduced leaf. |
|
indument |
|
STRUCTURE / SUBSTANCE |
|
See indumentum. |
|
pappus scale |
|
STRUCTURE |
|
A pappus element that is more or less planate and relatively thin and broad; may terminate in one or more awn- or bristle-like appendages. |
|
drooping |
|
orientation |
|
Erect to salient (patent, porrect, spreading) proximally and curving downward distally. |
|
alete |
|
architecture |
spore |
Lacking a tetrad scar (surficial ridge or angle resulting from coherence with others produced from the same spore mother cell). |
|
silicle |
|
nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
|
vascular |
|
position |
|
Upon or otherwise directly associated with the vasculature. |
|
elongate |
|
plane shape |
|
Longer in one dimension than in any other. |
|
andropetalous 1 |
|
architecture |
flower, androecium |
Having petaloid, sterile stamens. |
|
superposed 2 |
|
insertion |
buds |
Axillary in pairs, one member of each pair directly above the other. |
|
corolla pl. corollae, corollas |
|
STRUCTURE |
|
Collectively, the petals of a flower, whether distinct or connate; the inner or distal envelope of a differentiated perianth, whether the other envelope (calyx) is actually present or is deemed to be absent due to evolutionary reduction. |
|
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
solitary 1 |
|
arrangement |
|
Disposed singly, each remote from any others. |
|
villosulous |
|
pubescence |
|
Finely villose (shaggy, villous). |
|
antisepalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
