birettaform |

solid shape |
|
Approximately square in cross section and shallowly convex at the top; like a biretta (Roman Catholic cleric's hat). |
|
napiform |
= turnip-shaped |
solid shape |
|
Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. |
|
caudicle |
= translator arm |
STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
|
placentiform |
= placenta-shaped |
solid shape |
|
Thickly disciform (discoid); like the generalized shape of a human placenta. |
|
deliquescent 2 |
|
texture |
|
Delicately fleshy and liquifying at maturity or with pressure; e.g., petals of Tradescantia (Commelinaceae). |
|
rachis 1 var. rhachis |
|
STRUCTURE |
|
A main or first-order axis of a compound leaf blade. |
|
fixed |
|
fixation |
|
Attached to the bearing structure in a manner allowing no significant rotation or declination in relation to it. |
|
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
|
goblet-shaped |
= crateriform |
solid shape |
|
Having a distal, concave, relatively thin-walled, basically hemispherical portion surmounting a much narrower, transversely round, pedestal-like base. |
|
hypocotyl |
|
STRUCTURE |
|
That portion of an embryo axis between the level of cotyledon insertion above and the root meristem (or radicle, if present) below. |
|
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
tunic |
|
STRUCTURE |
|
A membranous covering outside the epidermis, especially around bulbs and corms, often becoming loose, sometimes scarious. |
|
wing 2 |
= ala |
STRUCTURE |
|
One of the two lateral petals in a papilionaceous corolla. |
|
capitate 3 |
= capitiform, head-shaped |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
|
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
|
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
|
phyllode |
= phyllodium |
STRUCTURE |
|
A leaf deemed to consist entirely or almost entirely of tissues evolutionarily derived from the petiole, all or a distal portion of which has become expanded and blade-like, the original blade reduced to the point of absence or vestigiality. |
|
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
|
pubescent 2 (strict sense) |
= downy |
pubescence |
|
Of or bearing relatively short, slender, soft, more or less erect, capillate trichomes. See also puberulent. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
|
duration |
|
CHARACTER |
|
Extent of lifetime, or persistence and physical state after maturation. |
|
rostellate |
= small-beaked |
apex |
|
Diminutively rostrate (beaked). |
|
felted |
> panniform, pannose |
pubescence |
|
Of or bearing closely intertwined, capillate trichomes that form a dense, felt-like mat. |
|
gelatinous |
|
texture |
|
Jelly-like; soft, moist, continuously cohesive, texturally homogeneous, somewhat resilient, and easily cut. |
|
square |
|
plane shape |
|
Equilaterally rectangular. |
