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. |
…adelphous |
|
architecture |
flower, androecium |
Having two or more distinct sets of stamens, the sets differing from one another in the arrangements, insertions, positions and/or morphologies of the included stamens, the number of sets indicated by the prefix, at least one set with two or more members; as in diadelphous, monadelphous, triadelphous. |
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. |
apiculum 1 pl. apicula |
|
STRUCTURE |
|
A short, slender, angular tip that is not notably harder or stiffer than the main body of the bearing structure. See also mucro. |
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. |
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
saprophytic |
|
nutrition |
plant |
Heterotrophic and obtaining essential nourishment directly from the decomposing remains of other organisms. |
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. |
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
isosepalous |
|
architecture |
flower, perianth, calyx |
Having the sepals essentially alike in size and shape. |
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
leptosporangiate |
|
reproduction |
|
Having relatively small sporangia each of which develops from a single initial cell that, by periclinal division, gives rise to an outer and an inner cell, the former then giving rise to the entire sporangium, including contents and sporangiophore, the latter contributing nothing to it; in some Polypodiophyta. |
latrorse |
|
dehiscence |
anther |
Opening laterally, on the tangential sides. See also extrorse, introrse. |
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. |
cymose |
|
architecture |
inflorescence |
Comprising one or more simple or compound cymes. See also cincinnate, cymulose, dichasiate, helicoid-cymose, monochasiate, rhipidiate, scorpioid-cymose. |
cuboid |
|
solid shape |
|
Generally but not strictly cubic; more or less equilaterally six-sided, each side basically square. |
neuter |
|
architecture |
flower, floret |
Lacking both stamens and pistils. |
dimidiate |
|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
syncarpous |
|
architecture |
flower, gynoecium |
Having one or more compound pistils. |
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
