induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
|
undulate |
= wavy |
margin |
|
Having regular, curved, smoothly connected, alternating, wave-like deviations upward and downward from the general plane of the structure. |
|

solid shape |
|
Having the number of lobes indicated by the prefix; as in bilobate. |

STRUCTURE |
|
The short, persistent, thickened, more or less erect, main stem of a perennial plant that otherwise has annual stems. |
|
pallid |
|
coloration |
|
Relatively pale; not strongly colored. |
|
connivent |
|
arrangement |
|
Converging and distally contiguous; esp. arcuate stamens with anthers contiguous. |
|
placentation |
|
CHARACTER |
|
Disposition of the placenta(e) within an ovary. |
|
rachilla 2 var. rhachilla |
|
STRUCTURE |
|
A second-order axis in an inflorescence, especially the axis bearing the florets in a spikelet; esp. in Cyperaceae, Poaceae (Gramineae). |
|
embryotega pl. embryotegae, embryotegas |
|
STRUCTURE |
|
A small, hardened, lid-like portion of the testa (seed coat) at the micropyle of some seeds, detaching at germination. |
|
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
|
fixation |
|
CHARACTER |
|
Mode of attachment to a supporting structure. |
|
glutinous 2 |
> mucilaginous, mucous, viscid |
texture |
|
Sticky or slimy. |
|
sterigma pl. sterigmata |
|
STRUCTURE |
|
A portion of a lamina that is prolonged and adherent to the supporting axis beneath the point of vascular insertion. |
|
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. |
