scarious |
|
texture |
|
Very thin, dry, and not green. |
mesochilium |
|
STRUCTURE |
|
The central portion of a labellum (lip) that has distinct proximal, distal, and central parts; in Orchidaceae. See also epichilium, hypochilium. |
apiculate |
|
apex |
|
Terminating abruptly in a short, slender, angular tip that is not notably harder or stiffer than the main body of the structure. See also mucronate, mucronulate. |
dimidiate |
|
solid shape |
|
Halved, figuratively; bilaterally asymmetric, nearly or wholly lacking one side as implicitly compared with some corresponding bilaterally symmetric structure, real or imagined. |
trichotomous |
|
architecture |
axis |
Branching by division of the apical meristem producing three coordinate but not necessarily equal derivatives from each division. |
acrodromous |
|
venation |
|
Having two or more primary and/or strongly developed secondary veins that diverge at or above the laminar base and are thence convergently arcuate toward the apex, reaching it or not. |
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
herb |
|
nominative |
plant |
Annual, biennial, or perennial with no woody (lignified) tissue in any part of the shoot; when persisting over more than one growing season, the parts of the shoot dying back seasonally. |
polygamous |
|
reproduction |
taxon |
Having both bisexual and unisexual flowers, borne on the same or on different plants. |
rhizophore |
|
STRUCTURE |
|
A stem branch that bears no leaves and from which roots eventually arise; esp. in Selaginellaceae. |
elliptic(al) 1 |
|
arrangement |
bundle scars |
Forming an ellipse |
follicetum pl. folliceta |
|
STRUCTURE |
|
An aggregate of follicles produced from a single flower with multiple simple pistils. |
homosporous |
|
reproduction |
taxon |
Producing only one type of spore, each spore giving rise to a gametophyte that bears gametangia of both sexual types. |
parietal |
|
placentation |
|
Upon the inner wall surface of a unilocular ovary, thus peripheral within the locule. |
germination 1 |
|
CHARACTER |
|
The process wherein a dormant embryo resumes active metabolism and growth, the primary root and shoot emerging from the seed coat, the young sporophyte thereupon entering the seedling stage. |
tetrad |
|
STRUCTURE |
|
A group of four pollen grains originating from a single pollen mother cell. |
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
basifixed |
|
fixation |
|
Attached at its base. |
spathe |
|
STRUCTURE |
|
A usually relatively large, sometimes showy, foliose bract subtending and sometimes partially enclosing an inflorescence, esp. a spadicate one; in Liliidae (monocotyledons). |
ochrea |
|
STRUCTURE |
|
See ocrea. |
nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
lineate 1 |
|
coloration |
|
Having very narrow, straight, clear or colored lines that contrast with the ground color. |
floral |
|
position |
|
Upon, within, or associated with the flowers. |
bulb |
|
STRUCTURE |
|
A thickened underground perennating structure consisting of a stem with numerous closely proximate nodes bearing many tightly imbricate, thickened, often fleshy, foliaceous organs containing large amounts of stored food, usually in the form of starch; the whole usually enveloped and protected by imbricated scarious or fibrous foliaceous organs. |
