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. |
|

|
Olfactory stimulation. |
|
cone scale |

|
commissure |
|
FEATURE |
|
Precisely, the joint or common boundary between the facing surfaces of two coherent or mutually appressed structures such as mericarps or stigmas, but traditionally (though imprecisely) applied to such a facing surface itself. |
|
horn |
= corniculum |
STRUCTURE |
|
A straight or curved, slenderly conic or conoidal protrusion or terminal portion that resembles an animal horn. |
|
streaked 2 |
= striate; < lineate |
relief |
|
Covered with very narrow and shallow, relatively long, more or less straight and parallel depressions. |
|
dome-shaped |
= tholiform |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
|
quadr(i)… |
= four-…, tetra… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in quadrangular, quadrilocular. |
|
microsporophyll |
> cone scale |
STRUCTURE |
|
A sporophyll that bears only microsporangia. |
|
venation |
|
CHARACTER |
|
Configuration of laminar vasculature as to its hierarchical organization and the dispositions of component orders. For descriptive purposes, the orders of vasculature are ranked with reference only to the lamina in point, irrespective of rank within any larger vascular context. |
|
carinate |
= keeled |
solid shape |
|
Having an elongate median longitudinal ridge that is basically triangular in transverse section, resembling the keel of a boat; esp. a leaf blade or sheath, glume, lemma, palea, sepal or petal. |
|
glochidiate |
|
pubescence |
|
Bearing glochids (glochidia). |
|
spatula-shaped |
= spatulate |
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. |
|
patelliform |
= kneecap-shaped |
solid shape |
|
Thickly meniscoid, like a human kneecap. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
placenta pl. placentae, placentas |
|
STRUCTURE |
|
An ovule-bearing zone of the tissue surface bordering an ovary locule; of merely topographic, not histological, significance; may be a part of the ovary wall proper or an extension from it, or a part of the central axis of the ovary or an extension from it. |
|
involucre 2 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts (phyllaries) surrounding (proximal to) the compound receptacle (torus) and florets of a capitulum (head); in Asteraceae (Compositae). |
|
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. |
|
rigid |
= rigent, stiff |
texture |
|
Strongly resisting deformation over its length. |
|
obdeltoid |
< three-angled, trigonous, triquetrous |
solid shape |
|
Three-angled (trigonous, triquetrous), broadest distally, and regularly attenuate to an angular base; inversely deltoid. |
|
close |
= approximate |
arrangement |
|
Disposed relatively near to one another. |
|
sterigma pl. sterigmata |
|
STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
|
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
|
lentiginose |
= dusty, lentiginous |
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. |
