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. |
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
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. |
dyad |
|
STRUCTURE |
|
A pair of coherent pollen grains shed as a unit. |
panicle |
|
nominative |
inflorescence |
A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |
umbellet |
|
nominative |
inflorescence |
A single set of pedicellate flowers in a compound umbel. |
terrestrial |
|
habit |
plant |
Growing upon the ground, usually rooted in it. |
epiphyllous |
|
insertion |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
pollen |
|
STRUCTURE |
|
Collectively, the spores or grains produced within the thecae of anthers, each containing a very small microgametophyte (or its evolutionary homologue); serving as disseminules from which microgametes are released after transport to a receptive micropylar pollen droplet (in Pinophyta) or stigma (in Magnoliophyta) by a variety of vectors, notably wind, water, insects, bats, and birds. |
wiry |
|
architecture |
axis |
Relatively very narrow and elongate, tough, and resiliently flexible. |
floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
wall (fruit, ovary, pollen, spore) |
|
STRUCTURE |
|
The exterior layer of tissue(s) enclosing anatomically distinct interior tissues and sometimes fluid and/or one or more cavities. |
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. |
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. |
