FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
craspedodromous, simple- |

venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
|
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). |
|
locule |
= cell (not recommended), chamber (not recommended) |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
|
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
|
obsolete (not recommended) |
= rudimentary; > vestigial |
manifestation |
|
Not developing fully and not functional compared with corresponding structures in other taxa. |
|
bellied |
= ventricose |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
runner |
= stolon |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
|
near-bald |
= glabrate |
pubescence |
|
Nearly glabrous, with only a very sparse covering of trichomes. |
|
ear |
= auricle |
STRUCTURE |
|
A small, rounded, lateral lobe at the base of a laminar structure, lying in more or less the same plane as the remainder of the lamina. |
|
glochid |
= glochidium; < bristle, capillus, hair, seta, trichome |
STRUCTURE |
|
A capillus (hair) or bristle (seta) that bears one or more barbs; esp. in Cactaceae. |
|
septum pl. septa |
> dissepiment, replum, trabecula |
STRUCTURE |
|
A topologically and/or texturally distinct wall or partition that separates chambers or locules within an ovary, fruit or sporangium. |
|
peripheral |
|
insertion |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
|
hepta… |
= seven-… |
prefix |
|
Indicating presence of or constitution by seven entities of the type denoted by the term's stem; as in heptacolpate, heptafoliolate, heptapterous. |
|
exalate 1 |
= wingless |
architecture |
|
Lacking elongate, relatively thin protrusions or appendages that resemble wings. |
|
scale 2 |
> lepis, squama, squamella, squamule; < trichome |
STRUCTURE |
|
A planate trichome. |
|
lamina 1 pl. laminae |
= blade |
STRUCTURE |
|
The expanded, more or less planate, distal portion, when present, of a leaf, leaflet or bract. |
|
forked |
= furcate; > bifurcate |
solid shape |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
raphides sing. raphis |
|
STRUCTURE |
|
Needle-like crystals of calcium oxalate contained within the cells of some plants; esp. in Araceae. |
|
corky |
= suberous |
texture |
|
Firm, relatively light, discontinuous but strongly cohesive, and resilient. |
|
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. |
|
placenta-shaped |
= placentiform |
solid shape |
|
Thickly discoid (disciform); like the generalized form of a human placenta. |
|
nodulose |
|
solid shape |
|
Diminutively nodose; esp. roots of Fabaceae (Leguminosae), the nodules harboring nitrogen-fixing bacteria. |
|
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
|
ring-porous |
|
porosity |
|
Heterogeneously porous, with macroscopically distinct concentric seasonal growth increments (rings), each with numerous large vessels toward the inside and fewer and smaller ones toward the outside. |
