lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
drupelet |
|
nominative |
fruit |
Diminutively drupe-like but derived from one of the simple, superior ovaries of an apocarpous flower, having a fleshy fruit wall and a hard seed (pyrene) within, a distinct constituent in an aggregate fruit; esp. in Rosaceae. |
decumbent |
|
habit |
axis |
Reclining upon the substrate proximally, ascending to erect distally. |
puberulent |
|
pubescence |
|
Finely pubescent in the restricted sense of that term. |
nutlet |
|
nominative |
fruit |
A small, relatively hard-coated mericarp; esp. in Lamiaceae (Labiatae), Verbenaceae. |
alete |
|
architecture |
spore |
Lacking a tetrad scar (surficial ridge or angle resulting from coherence with others produced from the same spore mother cell). |
mesocarp |
|
STRUCTURE |
|
The middle tissue layer of the pericarp of a fruit. |
reclinate |
|
vernation |
|
Each with its blade oriented downward and parallel to the proximal portion of its distally recurved petiole. |
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
andropetalous 1 |
|
architecture |
flower, androecium |
Having petaloid, sterile stamens. |
mottled |
|
coloration |
|
Having one or more indistinctly delineated, irregularly shaped, areas of varying size and contrasting hue and/or intensity. |
grumous |
|
solid shape |
|
Having an external aspect like a cluster of grains, basically convex overall. |
antipetalous |
|
position |
equivalent floral structures |
Each inserted directly above or below a petal. In place of this term, the phrase "opposite the petals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |
vesicle |
|
STRUCTURE |
|
A small bladder-like part consisting of an enclosing wall or covering and an empty or fluid-filled interior, sometimes turgid; esp. in citrus fruits (hesperidia). |
tuber |
|
STRUCTURE |
|
An enlarged, basically subterranean stem segment or thallus outgrowth containing a high proportion of storage tissue and functioning as a perennating and often vegetatively propagative structure. |
perfect |
|
architecture |
flower |
Having functional pistil(s) and functional stamen(s) both present, thus bisexual (hermaphroditic). |
tomentulose |
|
pubescence |
|
Finely tomentose. |
arcuate 2 |
|
plane shape |
|
Elongate and more or less regularly curved from one end to the other, one side convex, the opposite concave. |
secund 1 |
|
architecture |
inflorescence |
Having the pedicels oriented such that the main bodies of all the flowers lie to one side of the bearing axis. |
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
hypogynous |
|
insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
weeping |
|
architecture |
plant |
Having elongate, flexible, pendent branches. |
secund 2 |
|
architecture |
stem |
Having the petioles oriented such that the main bodies of all the leaves lie to one side of the bearing stem. |
