bristle 1 |
= arista, awn, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
epidermal cell |
|
STRUCTURE |
|
Any of the unspecialized cells of an epidermis; i.e., any other than stomatal guard cells or cells directly associated with trichomes. While the latter specialized cells are also properly epidermal cells, they are treated separately for descriptive purposes and, for the sake of convenience, use of the general term is restricted to the unspecialized cells that constitute the bulk of an epidermis. |
carpophore 3 |
= columella; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
diamond-shaped |
= rhomboid |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
lancehead-shaped 1 |
= lanceolate |
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. |
barbellulate |
|
architecture |
|
Bearing one or more barbellules (barbellulae). |
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
albumen |
= endosperm |
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. |
inflorescence 1 |
|
architecture |
|
Mode or progressive pattern of bearing flowers; most appropriately described using adjectival terms. |
fimbriate |
= fringed |
margin |
|
Regularly divided into slender, closely adjacent, more or less flexible segments, or having protrusions that give the appearance of such division. See also fimbrillate (fine-fringed). |
seven-… |
= hepta… |
prefix |
|
Indicating presence of or constitution by seven entities of the type denoted by the term's stem; as in seven-leafleted, seven-loculed, seven-winged. |
apical |
< distal |
insertion |
|
At or very near the developmental end or tip (apex) of a structure. |
platter-shaped |
= scutellate, scutelliform |
solid shape |
|
Relatively thin with opposite broad oval faces, shallowly concave-convex; like a serving platter. See also buckler-shaped (scutate, scutiform), which is not clearly distinct in its application. |
apical |
< distal |
position |
|
At or very near the developmental end or tip (apex) of a structure. |
taeniate |
= tapeworm-shaped |
solid shape |
|
Slender, elongate, basically cylindric or compressed-cylindric with shallow, narrow, more or less regular constrictions along its length, the whole apparently segmented and straight or variously curved. |
unilateral 2 |
= one-sided |
orientation |
|
Disposed or directed toward one side only. |
forked |
= furcate; > bifurcate |
solid shape |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
hypochilium |
|
STRUCTURE |
|
The proximal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also epichilium, mesochilium. |
rostellum 2 pl. rostella |
= beaklet |
STRUCTURE |
|
A sterile excrescent stigma lobe protruding between the anther and the functional stigma lobes of a column; sometimes forming one or more viscidia at pollinium maturity; esp. in Orchidaceae. |
blade |
= lamina |
STRUCTURE |
|
The expanded, more or less planate, distal portion, when present, of a leaf, leaflet or bract. |
oily 1 |
= greasy, oleaginous, unctuous |
coating |
|
Of a grease- or oil-like film. |
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
costal |
|
insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
puncticulate |
= small-dotted |
relief |
|
Finely punctate (dotted). |
farinose |
< mealy |
pubescence |
|
Bearing minute, relatively stout trichomes, collectively meal- or flour-like (farinaceous) and easily detached. See also farinaceous. |
