limb 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae). |
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
convolute 2 |
|
arrangement |
cotyledons |
Each rolled or folded inward longitudinally, one enveloping the other. |
silicle |

nominative |
fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
geminicolpate |
|
architecture |
pollen grain |
Having four or more surficial grooves (colpi) disposed in pairs. |
bottom-rooted |
|
habit |
plant |
Aquatic and rooted in the substrate beneath the water. |
disc 1 var. disk |
|
STRUCTURE |
|
Any distinct, annular to discoid structure produced from or borne upon a floral receptacle between or basal to any of the sets of floral organs; usually fleshy, often nectariferous. |
bulbel |
|
STRUCTURE |
|
A comparatively small bulb branching laterally from a larger, currently primary one. |
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. |
ramal |
|
position |
|
Upon or otherwise directly associated with the stem branches. |
basicaulous |
|
position |
|
At or very near the stem base. |
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
flagellum pl. flagella |
|
STRUCTURE |
|
A very slender whip-like structure that extends from the main body of an antherozoid and, by active undulation, propels the cell through a liquid medium. |
…porate |
|
architecture |
pollen grain |
Having the number of pores indicated by the prefix; as in monoporate, polyporate, triporate. |
epibracteal |
|
insertion |
|
Upon the bracts, or partially adnate thereto and apparently arising therefrom. |
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. |
valvate 2 |
|
arrangement |
planate structures |
Not overlapping, adjacent members laterally contiguous at their margins. |
heteropolar |
|
architecture |
pollen grain, spore |
Having morphologically evident polarity, the proximal and distal halves dissimilar. |
campylodromous |
|
venation |
|
Having several primary and/or strongly developed secondary veins that diverge from a point or small area near the base of the blade and run thence ultimately toward the apex, recurving proximally, arcuate and converging distally, reaching the apex or not. |
interrupted 1 |
|
architecture |
foliaceous structure |
Compound with the leaflets alternately large and small. |
erose 1 |
|
margin |
|
Having rough, very irregular depressions throughout. |
reproduction |
|
CHARACTER |
|
Type, morphology, disposition, function and/or dissemination of reproductive structures. |
limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
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. |
