staminal |
|
position |
|
Upon or otherwise directly associated with the stamens. |
bud |
|
STRUCTURE |
|
A rudimentary, unexpanded stem, stem branch, inflorescence, inflorescence branch, or flower, or a combination thereof, in a resting state; enveloped or not by subtending protective scales. |
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. |
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
dilate(d) |
|
solid shape |
elongate structure |
Narrow at one end and broadening toward the other; esp. when essentially terete at the narrow proximal end and seemingly flattened distally, as some anther filaments. |
multiciliate |
|
architecture |
|
Having several to many cilia. |
synanthous |
|
maturation |
non-floral structure |
Maturing at the same time as the flowers. See also coetaneous. |
ocrea pl. ocreae var. ochrea |
|
STRUCTURE |
|
A tubular sheath that encircles a stem at a node, subtending a petiole; thought to have arisen evolutionarily by lateral fusion of two stipules; in Polygonaceae. |
oblanceolate |
|
plane shape |
|
Inversely lanceolate (lancehead-shaped). |
thyrse |
|
nominative |
inflorescence |
An elongate, indeterminate main axis bearing numerous lateral branches, each the principal axis of a cymose subdivision. |
evergreen |
|
habit |
plant |
Perennial and bearing some viable leaves at all times during the yearly cycle. |
palmatipinnate |
|
architecture |
foliaceous structure |
Compound with two orders of leaflets, the first order palmate, the second pinnate. |
ternate |
|
architecture |
foliaceous structure |
Palmate with three leaflets. |
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
filamentous |
|
texture |
|
Composed of filiform (thread-like) strands with no intervening tissue. |
perforate |
|
architecture |
foliaceous structure |
Having portions of the laminar (blade) area naturally devoid of any tissue. |
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
follicle |
|
nominative |
fruit |
Dry, longitudinally dehiscent, one-locular, one- to many-seeded and derived from a single, superior, simple ovary; dehiscing along a single adaxial suture. |
winter annual |
|
nominative |
plant |
Annual, germinating in autumn, overwintering in a vegetative state (usually as a rosette aboveground), reproducing sexually from early spring through summer, and dying promptly thereafter. See also summer annual. |
pseudoaxillary |
|
position |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
waisted |
|
solid shape |
|
Constricted in width or breadth at or near the middle of its length. |
hirtellous |
|
pubescence |
|
Finely hirsute. |
anthela pl. anthelae |
|
nominative |
inflorescence |
A cyme with the main axis markedly shorter than the lateral axes, appearing generally paniculate when compound; esp. in Juncaceae. |
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
incurved |
|
orientation |
|
Curving adaxially. See also decurved. |
