flesh |
|
STRUCTURE |
|
Tissue that is fairly firm and dense, juicy or at least moist, and easily cut. |
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
sporophyll |
= spore leaf; > fertile frond |
STRUCTURE |
|
A leaf or homologous structure that bears sporangia. See also megasporophyll (macrosporophyll, not recommended), microsporophyll. |
pale 1 |
= palea, palet, receptacular bract |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle of a capitulum (head) in Asteraceae (Compositae). |
moniliform |
= beaded |
solid shape |
|
Elongate, relatively slender, transversely round, and more or less regularly constricted over its length, the whole straight or variously curved; like a necklace of beads. |
prophyllar |
|
insertion |
|
Upon or otherwise directly associated with the prophylls (bracteoles, bractlets). |
vestigial |
< obsolete (not recommended), rudimentary |
manifestation |
|
Not developing fully and not functional compared with corresponding structures in other taxa, and thought to have devolved to that state from a fully developed and functional structure in an ancestral taxon. |
…cyclic |
= …seriate, …verticillate, …whorled |
arrangement |
|
Disposed in the number of cycles (series, verticils, whorls) indicated by the prefix; as in monocyclic, 3-cyclic. |
lentiginous |
= dusty, lentiginose |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also pulverulent (granuliferous, powdery), which is not clearly distinct in its application. |
annulus 2 pl. annuli |
|
STRUCTURE |
|
A row of protruding specialized sporangial wall cells that extends upward from the base of the sporangium and over its apex, thus forming an incomplete circumferential ring; esp. in Polypodiophyta. The inner and radial walls of the annular cells are markedly thickened and the structure functions as a spore-releasing and -disseminating mechanism as a result of differential stresses developed within the mature sporangial wall upon desiccation. |
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
intravaginal |
|
insertion |
|
Within the leaf sheath. |
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
serrulate |
= small-sawtoothed |
margin |
|
Finely serrate (sawtoothed). See also crentate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed). |
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
spicule |
|
STRUCTURE |
|
A small, fine, stiff, acute protrusion that resembles a little spike. |
one-sided 1 |
= unilateral |
architecture |
|
Having only one side, as compared with presumably equivalent, bilaterally symmetric structures. |
crozier |
= fiddlehead |
STRUCTURE |
|
A circinate leaf (frond) prior to full expansion, while still wholly or distally coiled; esp. in Polypodiophyta. |
lanulose |
|
pubescence |
|
Finely lanate. |
standard |
= banner, vexillum |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
tomentose |
|
pubescence |
|
Bearing dense, short, stiff, capillate trichomes. See also tomentulose. |
dotted 2 |
= punctate |
relief |
|
Having small, round, shallow depressions or low protrusions. See also small-dotted (puncticulate). |
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
costa pl. costae |
= rib; > midnerve (not recommended), midrib, midvein; >< lateral vein |
STRUCTURE |
|
A primary vein of a laminar structure, having a longitudinal course, either medial or lateral, often prominent. See also secondary vein, tertiary vein, veinlet. |
