staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
craspedodromous, mixed- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
recurved |
= arching |
orientation |
|
Curving outward (abaxially), downward, or backward. |
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
involucral bract |
= phyllary; < bract (broad sense) |
STRUCTURE |
|
One of the bracts composing the involucre of a capitulum (head,); in Asteraceae (Compositae). |
shoot 2 |
|
STRUCTURE |
|
A vascularized axis that is differentiated into nodes and internodes and that branches exogenously from the former, together with any non-axial structures borne from it. |
friable |
= brittle |
texture |
|
Dry, firm and easily broken. |
arista pl. aristae |
= awn, bristle, 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). |
versatile |
|
fixation |
|
Attached in a manner allowing free rotation and declination. |
downy |
= pubescent |
pubescence |
|
Of or bearing relatively short, slender, soft, more or less erect, capillate trichomes. See also puberulent. |
overlapping 1 |
= imbricate(d) |
aestivation |
|
Having members whorled or spirally inserted and overlapping one another, each overlapping or overlapped to either side, and also above or below if spirally arranged or in multiple whorls. |
determinate |
|
development |
|
Having the terminal (central, apical, or distal) portion differentiating first and the lateral (peripheral, basal, or proximal) portions later, development thus proceeding sequentially downward or outward, growth of the whole thereby organizationally limited. |
lens-shaped 2 |
= biconvex, lenticular |
solid shape |
|
Relatively thin with two round, convex, opposite broad faces intersecting acutely at the circumferential edge; like a double-convex lens. See also disciform (discoid), meniscoid. |
glabrate |
= near-bald |
pubescence |
|
Nearly glabrous, with only a very sparse covering of trichomes. |
sporocarp |
= spore body |
STRUCTURE |
|
A multicellular structure that bears and more or less encloses several to (usually) many sporangia, the latter often aggregated into sori within it See also megasporocarp (macrosporocarp, not recommended), microsporocarp. |
chaff 2 |
|
STRUCTURE |
|
Collectively, the glumes, lemmata, and paleae of mature spikelets; in Poaceae (Gramineae). |
basicaulous |
|
insertion |
|
At or very near the stem base. |
penicillate |
= broom-shaped, muscariform |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
coriaceous |
= leathery |
texture |
|
Moderately thick, tough, and very pliable. |
callose |
= callous |
texture |
|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
infrabracteal |
|
insertion |
|
Upon the axis directly below a bract insertion. |
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
floral tube |
= floral cup (broad sense), hypanthium (broad sense) |
STRUCTURE |
|
A complex structure comprising fused portions of the perianth and/or androecium of a flower, sometimes also including receptacular tissue; surrounding and wholly, partly, or not at all adnate to the gynoecium; subdivided morphologically into casing, collar and/or neck; sometimes bearing free distal portions of the constituent structures. |
apiculum 2 pl. apicula |
|
STRUCTURE |
|
The apex of a connective, when prolonged above the union of the anthers. |
helmet-shaped |
= galeate, galeiform |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also hood-shaped (cucullate, cuculliform), which overlaps conceptually. |
