|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
…celled |
= …cellular |
architecture |
|
Having the number of cells indicated by the prefix; as in one-celled, few-celled, 5-celled. |
|
contorted 1 |
= convolute |
aestivation |
|
Imbricate and whorled, each member in turn overlapped by that to one side and overlapping that to the other, the whole tightly rolled and appearing as though twisted. |
|
plantlet |
|
STRUCTURE |
|
A juvenile, complete plant produced asexually by budding, as from the leaf margin in some Kalanchoë (Crassulaceae); this term is usually applied only while such vegetatively produced offspring remain attached to the plant of origin. |
|
…dentate 1 |
= …-toothed |
apex |
|
Generally truncate but with the number of antrorse, attenuate, distal lobes indicated by the prefix; as in tridentate. |
|
radiate 2 |
= radial, radiant, stellate |
arrangement |
|
Disposed about and mutually divergent from a common geometric center in two or three dimensions, thus collectively actinomorphic. |
|
endosperm |
= albumen |
STRUCTURE / SUBSTANCE |
|
A genetically triploid (3n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from fusion of the two polar nuclei (n + n chromosomes) of the embryo sac with a sperm nucleus from the pollen tube (n chromosomes). See also perisperm. |
|
sarcous |
= carnose, fleshy |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
|
flagellum pl. flagella |
|
STRUCTURE |
|
A very slender whip-like structure that extends from the main body of an antherozoid and, by active undulation, propels the cell through a liquid medium. |
|
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
|
granular |
= granulate, granulose |
texture |
|
Composed of grain-like particles; loose, dry, and coarsely particulate. |
|
stilt root |
|
STRUCTURE |
|
A relatively stout or strong adventitious root arising from a woody stem branch and extending downward directly toward the substrate, within which it ultimately becomes anchored, thus supporting the branch of origin; as in some Ficus (Moraceae). |
|
lanceolate |
= lancehead-shaped |
plane shape |
|
Elongate, moderately narrow, broadest just above the base and gradually attenuate toward the apex, the sides more or less straight; like the outline of the broad lateral face of a lance head. See also oblanceolate. |
|
twelve-… |
= dodeca… |
prefix |
|
Indicating presence of or constitution by twelve entities of the type denoted by the term's stem; as in twelve-loculed, twelve-stamened, twelve-styled. |
|
annulus 1 pl. annuli |
|
STRUCTURE |
|
A small ring-like protrusion from the strobilar stalk near its base and below the lowermost sporangiophores, sometimes bearing small sporangia; esp. in Equisetum. |
|
…morphic |
|
architecture |
|
Existing within the taxon in the number of distinct structural states indicated by the prefix, the states segregated in different sets of plants or not; as in monomorphic, polymorphic, trimorphic. |
|
carina 1 pl. carinae |
= keel |
STRUCTURE |
|
An elongate, median longitudinal ridge that is basically triangular in transverse section and resembles the keel of a boat; esp. in leaf blades and sheaths, glumes, lemmata, paleae, sepals, petals. |
|
osseous |
= bony |
texture |
|
Very hard and rather brittle, like bone. |
|
compact |
= congested, crowded |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
|
pinna pl. pinnae |
< leaflet |
STRUCTURE |
|
One of the first-order divisions or leaflets of a pinnate frond; in Polypodiophyta. See also pinnule. |
|
cyclic |
= seriate, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
|
pulviniform |
= cushion-shaped, mound-shaped, pulvinate |
solid shape |
|
Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. |
|
ear-shaped |
= auriform |
solid shape |
|
Resembling a mammalian outer ear. |
|
fertile frond |
< spore leaf, sporophyll |
STRUCTURE |
|
A frond that bears sporangia; in Polypodiophyta. See also sterile frond (trophophyll). |
|
setulose |
= hispidulous, small-bristly |
pubescence |
|
