suprabracteal |
|
position |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
mealy 2 |

theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
hemispheric(al) |
|
solid shape |
|
Half-spheric(al); broadest at the base and uniformly rounded to the apex, circular in any transverse section, and half-circular in any median longitudinal section. |
oblique 1 |
|
base |
|
Asymmetric about its longitudinal axis. |
pistil |
> carpel |
STRUCTURE |
|
Any simple or compound, discrete or histologically distinct, female (ovule-producing) floral structure, or any putatively homologous sterile structure; comprising an ovary and one or more stigmas borne either directly upon the ovary or upon one or more intervening styles. See also gynoecium. |
ring-shaped |
= annular |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
involucral bract |
= phyllary; < bract (broad sense) |
STRUCTURE |
|
One of the bracts composing the involucre of a capitulum (head,); in Asteraceae (Compositae). |
star-shaped 2 |
= stellate |
solid shape |
|
Having a distal aspect like the stylized shape of a star; stipitate or sessile with elongate branches or appendages radiating widely in three dimensions from a common point at the apex of the proximal axis or, when sessile, upon the bearing surface. |
erose 1 |
|
margin |
|
Having rough, very irregular depressions throughout. |
present |
|
presence |
|
Occurring within the context in point. |
macrosporangium pl. macrosporangia (not recommended) |
= megasporangium |
STRUCTURE |
|
A sporangium that produces megaspores. |
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
balding |
= glabrescent |
pubescence |
|
Becoming bald (glabrous, psilate) with age. |
foveolate |
= fine-pitted, scrobiculate |
relief |
|
Finely foveate (pitted). |
subterminal |
= subapical |
insertion |
|
Lateral and just below the apex. |
bundled 2 (not recommended) |
= fascicled, fasciculate |
arrangement |
|
Disposed in one or more fascicles, the members of each inserted close together and only slightly if at all divergent from one another. |
secondary root |
|
STRUCTURE |
|
Any root branch that originates directly or indirectly from a primary root. |
rachis 1 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of a compound leaf blade. |
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
decurved |
|
orientation |
|
Curving abaxially. See also incurved. |
nodal |
> interpetiolar |
insertion |
|
Upon or associated with the nodes. |
perisperm |
|
STRUCTURE / SUBSTANCE |
|
A genetically diploid (2n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from the nucellus. See also endosperm (albumen). |
