symmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are actinomorphic and equal in number of members. |
haplomorphic |
|
architecture |
flower |
Having the members of each set of basic floral structures numerous and spirally arranged, the flower hemispheric to conoidal overall. |
watery |
|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
pore |
|
FEATURE |
|
A small aperture or opening in a wall or covering that allows transport between interior and exterior. |
full |
|
extent |
|
Reaching from the ovary wall or pericarp to the center of the ovary or fruit and from the apex to the base of its interior, thus separating adjacent locules completely. |
clambering |
|
habit |
plant, axis |
Reclining upon and spreading across other plants or objects without the aid of special holding structures or growth patterns. |
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
extent |
|
CHARACTER |
|
Reach of the septum or septa within the ovary or fruit, relative to the ovary wall or pericarp and its center. |
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
submergent |
|
location |
structure of aquatic plant |
Descending from above the water surface to a point beneath it. |
collateral |
|
insertion |
buds |
In pairs within or immediately straddling the leaf axils, the members of a pair lateral to one another. |
fenestrate |
|
architecture |
pollen grain |
Having more or less isodiametric, regularly disposed lacunae. |
spicate |
|
architecture |
inflorescence |
Comprising one or more spikes. |
asymmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are irregular and/or unequal in number of members. |
bark |
|
STRUCTURE |
|
The outermost portion of any shoot or root axis having secondary growth, consisting of all those tissues outside the vascular cambium; sometimes exhibiting zonation into inner, living bark and outer, dead bark; usually described only as to external appearance. |
spore |
|
STRUCTURE |
|
A simple, usually unicellular, sometimes oligocellular propagule derived by meiotic division of a diploid (2n chromosomes) sporocyte within a sporangium, thus of haploid (n chromosomes) genetic constitution. A spore constitutes the first ontogenetic stage of a gametophytic generation and gives rise to a usually multicellular gametophyte upon germination. Though technically present in seed-bearing plants, by itself it is descriptively significant only in those taxa that do not produce seeds. |
heterogamous |
|
reproduction |
plant, inflorescence |
Having flowers that differ distinctly in size, shape and/or constitution. |
filament |
|
STRUCTURE |
|
The stalk, when present, of a stamen, clearly differentiated from and bearing at its summit an anther. |
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
barbed 2 |
|
solid shape |
|
Having one or more relatively short, stiff, acutely inserted or bent, antrorse or retrorse, terminal and/or lateral hook-like appendages; esp. awns or setae. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
unequal |
|
size |
equivalent structures |
Distinctly differing in extent. See also equal, subequal. |
naked 2 |
|
architecture |
bud |
Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. |
