solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
|
antipetalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
|
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. |
|
spinulose |
|
apex |
|
Finely spinose. |
|
arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
|
…ternate |
|
architecture |
foliaceous structure |
Compound with the number of orders of leaflets indicated by the prefix, each order ternate; as in biternate, thrice-ternate. |
|
pneumatophore |
|
STRUCTURE |
|
A structurally and functionally specialized root serving as an aboveground aerating organ; found in some woody taxa of wet habitats, notably some mangroves. |
|
asymmetric(al) 1 |
|
solid shape |
|
Not divisible into essentially equal halves along any line or plane. |
|
oblique 2 |
|
orientation |
planate lateral structure |
Lying in a plane not coincident with the one defined by its longitudinal axis and that of the bearing structure. |
|
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). |
|
seedling |
|
PLANT |
|
A plant in the first stages of its growth following emergence from the seed. |
|
tunic |
|
STRUCTURE |
|
A membranous covering outside the epidermis, especially around bulbs and corms, often becoming loose, sometimes scarious. |
|
disk |
|
STRUCTURE |
|
See disc. |
|
acroramous |
|
architecture |
axis |
Branching at or near the apex. |
|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
pterocaulous |
|
architecture |
plant |
Having alate (winged) stems. |
|
unequal |
|
size |
equivalent structures |
Distinctly differing in extent. See also equal, subequal. |
|
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. |
