position |
|
Within, upon, or otherwise directly associated with the bark. |
|
non-septate |
|
architecture |
trichome |
Lacking transverse inter- or intracellular septa or partitions. |
|
secund 1 |
|
architecture |
inflorescence |
Having the pedicels oriented such that the main bodies of all the flowers lie to one side of the bearing axis. |
|
dichlamydeous |
|
architecture |
flower |
Having a perianth differentiated into a distinct calyx (sepals) and corolla (petals). |
|
spinulose |
|
architecture |
|
Finely spinose. |
|
pollinial |
|
arrangement |
pollen |
Polyadal with the grains of individual thecae (pollen sacs), or of fused thecae, compacted and forming tightly coherent masses (pollinia) that constitute the basic dispersal units, these sometimes distally attenuate to a sterile caudicle (translator arm), sometimes united by caudicles in groups of two or more, the caudicle(s) sometimes attached to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
adenopetalous 2 |
|
derivation |
flower, perianth, corolla |
Having petals derived from glandular structures. |
|
shoot 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the root, the component axes differentiated into nodes and internodes, and branching exogenously from the former. |
|
face |
|
FEATURE |
|
A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. |
|
septifragal |
|
dehiscence |
fruit |
Splitting through the exterior wall suture(s) but not the septum(-a), the valves of the wall then separating from the septum(-a) and the locules thus opened directly to the outside. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
disk |
|
STRUCTURE |
|
See disc. |
|
lateral |
|
insertion |
|
To, toward, at, or upon a side, not apical or basal. |
|
lateral |
|
position |
|
To, toward, at, or upon a side, not apical or basal. |
|
multiciliate |
|
architecture |
|
Having several to many cilia. |
|
prismatic |
|
solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |
|
lemma pl. lemmata, lemmas |
|
STRUCTURE |
|
The proximal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) floret; the other is the palea. |
|
periclinal |
|
orientation |
|
Parallel to some given plane of reference; applied especially to the plane of cell division when it is oriented parallel to the generalized plane of the structural surface. |
|
appendage |
|
STRUCTURE |
|
Any subordinate structure ontogenetically derived from and associated with a given organ or part. |
|
vallecular |
|
position |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
|
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. |
|
panicle |
|
nominative |
inflorescence |
A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |
|
involucre 1 |
|
STRUCTURE |
|
One or more closely proximate whorls, or a compact spiral, of bracts immediately subtending an inflorescence, the bracts sometimes leaf-like, sometimes petaloid. |
|
circinate 2 |
|
vernation |
|
Having each leaf (frond) rolled adaxially from the sides and downward from the apex, forming a tight, flat coil; esp. in Polypodiophyta. |
