…grooved |
= …colpate, …fossulate, …furrowed, …sulcate, …valleculate |
architecture |
|
Having the number of grooves indicated by the prefix; as in three-grooved, 5-grooved. |
|
stolon |
= runner |
STRUCTURE |
|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
|
taproot |
< primary root |
STRUCTURE |
|
A primary root that remains dominant through the life of the plant as the main axis of a vertically oriented system that penetrates the substrate to a considerable depth. |
|
latex pl. latices, latexes |
|
SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
antherozoid |
= spermatozoid; < sperm |
STRUCTURE |
|
A motile male gamete, produced within an antheridium. |
|
bell-shaped |
= campanulate |
solid shape |
|
Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
mucro pl. mucrones, mucros |
|
STRUCTURE |
|
A short, hard, apical point that is a continuation of vascular tissue. See also apiculum. |
|
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
|
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
pungent 2 |
= acrid |
odor |
|
Sharp or astringent. |
|
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
rudimentary |
= obsolete (not recommended); > vestigial |
manifestation |
|
Not developing fully and not functional compared with corresponding structures in other taxa. |
|
fiddlehead |
= crozier |
STRUCTURE |
|
A circinate leaf (frond) prior to full expansion, while still wholly or distally coiled; esp. in Polypodiophyta. |
|
shiny |
= glossy, laevigate, lustrous, polished, shining |
reflectance |
|
Uniformly reflecting a high proportion of incident light at all angles. |
|
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
|
staminode |
= staminodium |
STRUCTURE |
|
Any sterile structure deemed to represent a modified stamen, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes petaloid, sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
hook-shaped |
= unciform |
solid shape |
|
Very slenderly elongate with a more or less straight proximal portion and a recurved terminal portion, the whole resembling a hook. |
|
surficial |
= superficial |
position |
|
Directly upon the surface of the structure in point. |
|
labium pl. labia |
= lip; > labellum |
STRUCTURE |
|
Any substructure that resembles a lip, especially a portion of a perianth, calyx or corolla; in Lamiaceae (Labiatae) sometimes restricted to the abaxial (lower) of the two corolla lips. |
|
truncate 2 |
|
base |
|
Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|
androecium pl. androecia |
|
STRUCTURE |
|
The stamen(s), staminode(s), if any, and their ontogenetically associated structure(s), if any, of a single flower, taken collectively. |
|
banner |
= standard, vexillum |
STRUCTURE |
|
The relatively large, erect adaxial (upper) petal in a papilionaceous corolla. |
|
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. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
