|
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. |
|
laminar 1 |
|
insertion |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
tumid |
= swollen, turgid |
solid shape |
|
Engorged in appearance, convex overall with the surface appearing taut , as though from internal pressure. See also inflated, which is not clearly distinct in its application. |
|
wing 1 |
= ala |
STRUCTURE |
|
Any elongate, relatively thin protrusion or appendage. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
capitate 2 |
= headed |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
|
operculum pl. opercula |
= lid |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of an ascidium (pitcher), pollen grain, pyxis, or sporangium (spore case). |
|
column 1 |
= gynandrium, gynostemium |
STRUCTURE |
|
A central floral structure consisting of the partly to wholly fused (connate and adnate) androecium and gynoecium; esp. in Orchidaceae. |
|
phylloclade |
= cladode, cladophyll |
STRUCTURE |
|
A stem segment that functions as a leaf; often more or less compressed. |
|
cushion-shaped |
= mound-shaped, pulvinate, 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. |
|
pubescent 1 (broad sense) |
|
pubescence |
|
Bearing trichomes. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
|
duplicate 2 |
= conduplicate |
vernation |
|
Each leaf folded sharply inward along its longitudinal axis, the adaxial surfaces of each side facing one another. |
|
feather-shaped |
= plumose |
solid shape |
|
Having a slender central axis bearing two opposite ranks of numerous, closely proximate, ascending, very slender branches or appendages; resembling the generalized form of a feather. |
|
serrulate |
= small-sawtoothed |
margin |
|
Finely serrate (sawtoothed). See also crentate (scalloped), crenulate (small-scalloped), dentate (toothed), denticulate (small-toothed). |
|
squamule 3 |
= lodicule, squamella |
STRUCTURE |
|
One of two or three small, scale-like structures inserted at the base of the androecium, distal to the palea, in most grass (Poaceae) flowers; often regarded as a vestigial branch or perianth member. |
|
hirtellous |
|
pubescence |
|
Finely hirsute. |
|
superposed 1 |
|
arrangement |
|
Approximate to congested, inserted directly above and below one another. |
|
keeled |
= carinate |
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. |
|
villose |
= shaggy, villous |
pubescence |
|
Bearing sparse, long, slender, soft, capillate trichomes that are not intertwined. See also villosulous. |
|
awl-shaped 1 |
= subulate |
plane shape |
|
Narrowly triangular or truncate-triangular and broadest at the base; like the outline of the lateral face of an awl. |
|
megasporophyll |
= macrosporophyll (not recommended); > carpel, cone scale, ovuliferous scale |
STRUCTURE |
|
A sporophyll that bears only megasporangia and, in Pinophyta, naked ovules that develop subsequently. |
|
obtrullate |
= obtrulliform |
plane shape |
|
Inversely trullate (trowel-shaped, trulliform). |
|
crisped |
= crispate, curly |
margin |
|
Having closely and irregularly spaced, irregularly shaped, often compound convexities that curve irregularly through three dimensions. |
|
distant |
= remote |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
rhachilla |
|
STRUCTURE |
|
See rachilla. |
