partite |
? cleft, dissected, divided, lobate, lobed, parted, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protrusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |

recurved |
= arching |
orientation |
|
Curving outward (abaxially), downward, or backward. |
|
episepalous |
|
position |
|
Upon the sepals, or partially adnate thereto and apparently arising therefrom. |
|
spatulate var. spathulate |
= spatula-shaped |
plane shape |
|
Elongate, broadest near a rounded apex, gradually attenuate to a narrower base; like the outline of the broad face of a spatula blade. |
|
strigulose |
= strigillose |
pubescence |
|
Finely strigose. |
|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
|
testes-shaped |
= testicular |
solid shape |
|
Bilaterally symmetrical, each side essentially oblate and constrictedly confluent with the other; like the overall shape of a pair of mammalian testes. |
|
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
|
acerose |
= acicular, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |
|
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
|
acetabuliform |
|
solid shape |
|
Transversely circular, broader than long, widest near or at the middle, relatively thin-walled, the hollow interior open distally; like a shallow bowl with strongly incurved sides. |
|
blotch |
= macula, spot |
FEATURE |
|
An area that differs in color from the rest of a structure's surface. See also eyespot. |
|
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. |
