rugulose |
|
relief |
|
Slightly or finely rugose (corrugate, wrinkled). |
throat 1 |
|
STRUCTURE |
|
The far distal portion of a perianth, calyx, or corolla tube, or of a leaf sheath, surrounding the orifice of the tube or sheath, sometimes constricted relative to the diameter of the main body of the tube or sheath; except in disc florets of Asteraceae (Compositae). |
cymulose |
|
architecture |
inflorescence |
Comprising one or more cymules. |
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
ligulate 2 |
|
architecture |
floret |
Bisexual with a zygomorphic corolla; in Asteraceae (Compositae). |
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
odor |
|
CHARACTER |
|
Olfactory stimulation. |
trapeziform |
|
plane shape |
|
Four-sided and either asymmetrical or bilaterally symmetrical like a triangle truncated distally perpendicular to its central axis. |
second glume |
|
STRUCTURE |
|
The upper (distal) member of a pair of small bracts inserted at the base of a grass (Poaceae) spikelet. |
disc 2 var. disk |
|
STRUCTURE |
|
Collectively, the disc florets of a capitulum (head), or the surface presented by them. |
floating 1 |
|
habit |
plant |
Buoyant and growing entirely at or near the surface of water, not rooted in any substrate. |
longitudinal 1 |
|
dehiscence |
|
Parallel to the central axis. |
pseudoaxillary |
|
position |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
aciculate |
|
coloration |
|
Having fine, irregularly oriented, straight streaks of contrasting hue and/or intensity. |
floating 2 |
|
location |
|
At or upon the surface of water. |
longitudinal 2 |
|
orientation |
|
Parallel to the long axis of the context of reference. |
pseudobulb |
|
STRUCTURE |
|
An enlarged internode of an aboveground stem, storing water and photosynthate, resembling a bulb; esp. in Orchidaceae. |
coetaneous |
|
maturation |
dissimilar structures |
Maturing concurrently. This adjective is frequently used to mean contemporary maturation of leaves and flowers, but without actually stipulating that those are the structures involved. Such usage is erroneous according to the construction and literal meaning of the term, which properly applies to structures, not to the taxon or plant. See also synanthous. |
marginal |
|
position |
|
Upon or otherwise directly associated with the margins. |
concentric |
|
position |
|
Having a center or axis of symmetry coincident with that of the context of reference. |
bud |
|
STRUCTURE |
|
A rudimentary, unexpanded stem, stem branch, inflorescence, inflorescence branch, or flower, or a combination thereof, in a resting state; enveloped or not by subtending protective scales. |
vallecular |
|
position |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
elaminate |
|
architecture |
foliaceous structure |
Lacking an expanded, more or less planate, distal portion (lamina or blade). |
anatropous |
|
orientation |
ovule |
Having the funiculus distally recurved and the (straight) ovule lying beside and parallel to the proximal portion of the funiculus, to which it may be adnate or adherent, the micropyle facing the ovary wall (placenta). |
fusion |
|
CHARACTER |
|
Physical connection of equivalent or dissimilar structural entities (as recognized on evolutionary, morphological, anatomical, ontogenetic, and/or topological grounds). Terms that denote the interconnection of equivalent structures are predicated on a single collective subject and suffice in themselves to describe the condition; e.g., "sepals connate." However, those that denote the connection of dissimilar structures require explicit notation of each type of structure involved, in either a compound-subject construction or else a single-subject/object-of-preposition construction; e.g., "stamens and corolla adnate" or "stamens adnate to corolla." Qualifying detail is sometimes appropriate; e.g., "filaments connate basally," "filaments adnate to the petals over their lower halves." |
