foliar |
|
position |
|
Upon or otherwise directly associated with the leaves. |
|
geminicolpate |
|
architecture |
pollen grain |
Having four or more surficial grooves (colpi) disposed in pairs. |
|
epidermal cell |
|
STRUCTURE |
|
Any of the unspecialized cells of an epidermis; i.e., any other than stomatal guard cells or cells directly associated with trichomes. While the latter specialized cells are also properly epidermal cells, they are treated separately for descriptive purposes and, for the sake of convenience, use of the general term is restricted to the unspecialized cells that constitute the bulk of an epidermis. |
|
actinocytic |
|
architecture |
stomate |
Having several subsidiary cells oriented radially to its center. |
|
gynobasic |
|
insertion |
style |
Apparently arising from the ovary base. |
|
false |
|
derivation |
indusium |
Constituting a marginal fold of the lamina as a whole and not a distinct enation from the epidermis. |
|
capitulescence |
|
architecture |
|
Mode or progressive pattern of bearing capitula (heads); most appropriately described using adjectival terms; esp. in Asteraceae (Compositae). |
|
heterocolpate |
|
architecture |
pollen grain |
Having long, narrow, regularly disposed lacunae (pseudocolpi). |
|
tertiary vein |
|
STRUCTURE |
|
A strand belonging to the third order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching from a primary or secondary vein. See also costa, lateral vein, primary vein, rib, secondary vein, veinlet. |
|
appendage |
|
STRUCTURE |
|
Any subordinate structure ontogenetically derived from and associated with a given organ or part. |
|
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
|
involucral |
|
derivation |
aril |
Produced from or a modification of a persistent involucre investing the seed. |
|
rhizomatous |
|
architecture |
plant |
Having rhizomes. |
|
inframedial |
|
insertion |
|
Slightly below the middle of the structure in point. |
|
mucro pl. mucrones, mucros |
|
STRUCTURE |
|
A short, hard, apical point that is a continuation of vascular tissue. See also apiculum. |
|
petiolar |
|
position |
|
Upon or otherwise directly associated with the petioles. |
|
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. |
|
vallecular |
|
position |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
decompound |
|
architecture |
|
Comprising two or more orders of equivalent substructural entities; multiply compound. |
|
ocrea pl. ocreae var. ochrea |
|
STRUCTURE |
|
A tubular sheath that encircles a stem at a node, subtending a petiole; thought to have arisen evolutionarily by lateral fusion of two stipules; in Polygonaceae. |
|
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
|
oblanceolate |
|
plane shape |
|
Inversely lanceolate (lancehead-shaped). |
|
present |
|
presence |
|
Occurring within the context in point. |
|
palmatipinnate |
|
architecture |
foliaceous structure |
Compound with two orders of leaflets, the first order palmate, the second pinnate. |
|
anisopetalous |
|
architecture |
flower, perianth, corolla |
