endocarp |
|
STRUCTURE |
|
The innermost tissue layer of a pericarp. |
|
sapwood |
|
STRUCTURE |
|
That portion of the wood (xylem) of a stem or root whose cells are still living and functional; concentric about the heartwood once the latter has begun to form. |
|
flaccid |
|
texture |
|
Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). |
|
single-veined |
= hyphodromous, one-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
…gonous |
= …angled |
solid shape |
|
Elongate with the number of longitudinal angles indicated by the prefix, the intervening sides transversely straight to concave; as in hexagonous, trigonous. See also deltoid, …gonal (…angular), obdeltoid, triquetrous. |
|
stigma pl. stigmata, stigmas |
|
STRUCTURE |
|
An exposed, localized portion of a pistil that retains deposited pollen and stimulates its germination, the pollen tubes then growing through or along it toward the ovule(s). |
|
flagelliform |
= whip-like |
solid shape |
|
Very slender, terete, generally straight, and apparently supple. |
|
sinistrorse |
= leftward |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also dextrorse (rightward). |
|
lancehead-shaped 2 |
= lanceoloid, lanciform |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanceoloid (oblanciform). |
|
turnip-shaped |
= napiform |
solid shape |
|
Depressed-globose overall and strongly concave-tapered (acuminate) at the base; like the generalized form of a turnip. |
|
annular |
= ring-shaped |
solid shape |
|
More or less evenly tubular in a closed circle; like a ring or doughnut. |
|
comose |
|
pubescence |
|
Bearing a prominent single tuft of relatively long and slender, flexible, capillate trichomes (coma). |
|
pilosulous |
|
pubescence |
|
Finely pilose. |
|
cycle |
= series, verticil, whorl |
STRUCTURE |
|
A set of three or more lateral structures that are inserted around an axis at the same level. |
|
pulvinate 2 |
= cushion-shaped, mound-shaped, pulviniform |
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 |
= auricle |
STRUCTURE |
|
A small, rounded, lateral lobe at the base of a laminar structure, lying in more or less the same plane as the remainder of the lamina. |
|
rostrum 2 pl. rostra |
= beak |
STRUCTURE |
|
The inner, horn-like segment of a coronal lobe; esp. in Asclepiadaceae. |
|
setose |
= hispid; < bristly |
pubescence |
|
Bearing relatively long and slender, more or less straight, terete, fine-pointed, stiff trichomes. See also setulose (hispidulous, small-bristly). |
|
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
|
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
|
triquetrous |
= three-angled, trigonous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
|
viscid 1 |
< glutinous |
coating |
|
Of a sticky substance. |
|
axil |
|
FEATURE |
|
The space bounded by and near the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
|
mentum pl. menta |
= column foot |
STRUCTURE |
|
A lateral, often nectariferous protrusion from the proximal portion of a column, opposite the labellum, projecting in front of the rest of the flower; in Orchidaceae. |
|
callous |
= callose |
texture |
|
Hard-leathery; callous tissue usually is also thicker than comparable adjacent tissue. |
