Pinnately divided. |
|
adventitious bud |
|
STRUCTURE |
|
A vegetative or floral bud that arises directly from a root or from some site on a shoot other than a leaf axil or stem apex. |

STRUCTURE |
|
A root that arises laterally from some part of a shoot, often from the lower portion of a main stem. |
|
fibrous root |
< diffuse root |
STRUCTURE |
|
A diffuse root that includes a significant component of woody or sclerotic strands and is consequently tough and often wiry. |
|
scallop |
= crena |
FEATURE |
|
A rounded, marginal convexity or concavity in a series of such that alternate regularly and are oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scalloplet (crenule), tooth (dens), toothlet. |
|
…colpate |
= …fossulate, …furrowed, …grooved, …sulcate, …valleculate |
architecture |
|
Having the number of colpi indicated by the prefix; esp. pollen grains; as in monocolpate, polycolpate, 3-colpate. |
|
axile |
|
placentation |
|
Upon the central axis of a compound, plurilocular ovary. |
|
staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
|
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. |
|
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
|
endophytic |
|
habit |
|
Growing within some portion of another, unrelated, living plant. |
|
main stem |
= primary stem; > bole, trunk |
STRUCTURE |
|
The one, or any of the more than one, first-order stem(s), or first-order portion(s) of the collective stem, of a shoot. |
|
short-shoot |
= spur |
STRUCTURE |
|
A first- or higher-order woody stem branch having relatively unelongated internodes, thus proximate nodes, and limited duration of growth, usually branching little if at all; often a main locus of flower production; usually more or less perpendicular to the axis that bears it and resembling a spur projecting from it; sometimes becoming more or less spinose after elongation ceases; esp. in Rosaceae. |
|
crateriform |
= goblet-shaped |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
|
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. |
|
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
|
laciniate |
= slashed; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|
receptacular bract |
= pale, palea, palet |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle (torus) of a capitulum (head) in Asteraceae (Compositae). |
|
exudation |
|
CHARACTER |
|
Discharged substance, as to type. |
|
S-shaped 2 |
= sigmoid |
solid shape |
|
Elongate with more or less constant width or diameter and curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
|
mushroom-shaped |
= fungiform |
solid shape |
|
Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
|
claw |
= unguis |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
|
waxy 2 |
= ceraceous, cereous, waxy |
texture |
|
Having the consistency of wax. |
|
articulation |
= joint |
STRUCTURE |
|
A distinct, relatively narrow zone of demarcation between adjacent main portions of an elongate structure, often thicker than the rest of the structure and sometimes a site of eventual abscission. |
