arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
linear 2 |
|
plane shape |
|
Elongate and narrow with the sides more or less straight and parallel over most of its length. |
|
stephanocolporate |
|
architecture |
pollen grain |
Stephanocolpate, each groove containing a pore. |
|
fissure |
|
FEATURE |
|
A relatively narrow, split or crack in the outer tissue(s) of a structure. |
|
trilete |
|
architecture |
spore |
Having a triradiate tetrad scar. |
|
dichotomous |
|
architecture |
axis |
Branching by division of the apical meristem producing two coordinate but not necessarily equal derivatives from each division. |
|
hypocotyl |
|
STRUCTURE |
|
That portion of an embryo axis between the level of cotyledon insertion above and the root meristem (or radicle, if present) below. |
|
actinocytic |
|
architecture |
stomate |
Having several subsidiary cells oriented radially to its center. |
|
flower |
|
STRUCTURE |
|
A functionally integrated, complex structure comprising sets of sporophytic and/or associated sterile structures disposed in standard sequence along a common axis; consisting of one or more constituent members each of, in ascending (proximal to distal) order of insertion, perianth (tepals, or else sepals and/or petals), androecium (stamens, staminodes and/or other associated structures), and/or gynoecium (pistils and/or other associated structures), the foregoing all borne laterally from the distal portion (receptacle) of the axis; depending upon the combination of structures present, may be bisexual, staminate only, pistillate only, or sterile; characteristic of and unique to the Magnoliophyta (Angiospermae). When a fertile androecium and gynoecium are both present a flower is termed perfect. When perfect and also with calyx and corolla both present, a flower is termed complete. Both terms are somewhat archaic and of limited descriptive value. |
|
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
|
strict |
|
course |
|
Lacking any curve or bend. |
|
colporate |
|
architecture |
pollen grain |
Having one or more elongate, relatively narrow and shallow depressions (colpi), each containing a pore. |
|
parallelodromous |
|
venation |
|
Having two or more primary veins that run more or less parallel to one another over most of the laminar length and converge near the apex. |
|
fruit |
|
STRUCTURE |
|
Any unitary seed-bearing structure of a flowering plant, consisting of the matured or ripened pistil(s) of one or more flowers along with any other floral or vegetative tissue(s) persisting adnate to them; characteristic of and unique to Magnoliophyta (Angiospermae). |
|
racemose |
|
architecture |
inflorescence |
Comprising one or more racemes. |
|
bulliform |
|
solid shape |
|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
|
interrupted 1 |
|
architecture |
foliaceous structure |
Compound with the leaflets alternately large and small. |
|
pepo |
|
nominative |
fruit |
Like a berry but derived from a single, inferior, compound ovary, with accessory floral-tube tissue adnate to the pericarp, having a relatively thin, hard or leathery rind and a thicker, fleshy inner wall that surrounds a mass of seeds; esp. in Cucurbitaceae. |
|
vasculature |
|
STRUCTURE |
|
The vascular strands of all orders (veins and veinlets) in a particular part or organ, regarded collectively; consisting of conducting tissues (xylem, phloem) and associated supporting and enclosing tissues (e.g., sclerenchyma, collenchyma). |
|
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
|
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
|
corolla tube 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret proximal to the level of filament insertion; in Asteraceae (Compositae). |
|
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
|
spadicate |
|
architecture |
inflorescence |
Generally spicate but with the flowers embedded in a thick, fleshy axis, the whole subtended and usually partially or wholly enveloped by a large bract (spathe). |
