|
perennate |
|
duration |
structure |
Persisting in a functional state through the entire growing season. |
|
veinlet |
|
STRUCTURE |
|
A strand belonging to the ultimate (least in diameter) order of vasculature in a leaf or other basically laminar structure when that order consists of strands ending freely within areoles and/or connecting distally by pairs across areoles; absent in some taxa. See also costa (rib), lateral vein, midvein (midnerve, midrib), primary vein, secondary vein, tertiary vein, vein (nerve). |
|
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
|
farina pl. farinae, farinas |
|
SUBSTANCE |
|
A dry, meal- or flour-like covering. |
|
pliestesial |
|
duration |
plant |
Perennial and monocarpic, living several to many years before reproducing sexually, dying promptly thereafter. |
|
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
|
funicular |

derivation |
aril |
Produced from or a modification of the funiculus (funicle). |
|
radical |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the root. |
|
habit |
|
CHARACTER |
|
General appearance and/or function, usually including explicit or implicit reference to one or more aspects of habitat or other features of the external environment; a logically imprecise traditional category of terms that overlaps conceptually with architecture, arrangement, duration, insertion, location, orientation, position, shape, and texture. |
|
radical |
|
position |
|
Upon, arising from, or otherwise directly associated with the root. |
|
haft |
|
STRUCTURE |
|
The narrow portion of a structure that is notably constricted. |
|
rhizoid |
|
STRUCTURE |
|
Any structure that is similar to a root in appearance and function but that is not a true root ontogenetically and anatomically, especially one produced from a gametophyte thallus. |
|
hilum 2 pl. hila |
|
FEATURE |
|
The more or less central point within a starch grain of intracellular origin, about which the successive layers of starch were accreted more or less symmetrically. |
|
crassate |
|
architecture |
|
Relatively thick for the type of structure or in the taxonomic context. |
|
included |
|
position |
anther, style |
Not protruding beyond the floral envelope. See also exsert(ed). |
|
hygroscopic |
|
architecture |
structure |
Increasing or decreasing in size according to the presence or absence of surrounding moisture, due to differential swelling or shrinking of component anatomical structures. |
|
apocarpous |
|
architecture |
flower, gynoecium |
Having two or more simple pistils (carpels). |
|
cymule |
|
nominative |
inflorescence |
A diminutive cyme, with few flowers, few or no branches, and short axes. |
|
irregular 1 |
|
architecture |
perianth, calyx, corolla |
Imperfectly actinomorphic, the constituents disposed symmetrically but unequal in size and/or shape. See also peloric. |
|
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
|
aggregate fruit |
|
nominative |
fruit |
Compound and derived from the two or more simple, superior ovaries of a single apocarpous flower; the ovaries connate, coherent, or contiguous in the fruit, the whole with or without accessory tissue. |
|
lateral |
|
insertion |
|
To, toward, at, or upon a side, not apical or basal. |
|
spicy |
|
odor |
|
Pleasantly pungent, reminiscent of spices. |
|
lip cell |
|
STRUCTURE |
|
Either of a pair of adjacent, narrow, transversely oriented, thick-walled cells bordering the pore (stomium) of a sporangium. |
|
stigmatic |
|
habit |
trichome |
Borne on the surface of the stigma and serving to hold pollen deposited there, variously shaped, often glandular, sometimes contractile. |
