STRUCTURE |
|
A relatively small outgrowth from an otherwise regular boundary or surface of a larger structure. |
|
suprafoliar |

|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
|
bursicle |
|
STRUCTURE |
|
A pouch- or flap-like protrusion from the stigma that encloses the caudicle of a pollinium. |
|
tomentose |
|
pubescence |
|
Bearing dense, short, stiff, capillate trichomes. See also tomentulose. |

exindusiate |
|
architecture |
sorus |
Lacking an indusium. |
|
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
|
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. |
|
fastigiate |
|
arrangement |
branches |
Closely parallel to one another and to the axis of origin over most of their lengths. |
|
pollinium pl. pollinia |
|
STRUCTURE |
|
A mass of coherent pollen grains disseminated as a unit by adhering to a pollinating insect, representing the entire content of a single theca or of fused thecae; often distally attenuate to a sterile caudicle (translator arm), which may attach to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
woody-clumping |
|
habit |
plant |
Having or developing the character of a woody clump. See also arboreous, arborescent, bushy, frutescent, fruticose, shrubby, subshrubby, suffrutescent, suffruticose, tree-like. |
|
floral |
|
insertion |
|
Upon, within, or associated with the flowers. |
|
pseudopetiole |
|
STRUCTURE |
|
A distinctly constricted, more or less stalk-like, proximal portion of a leaf, evolutionarily derived from the blade, the original petiole reduced to the point of absence or vestigiality; esp. in Poaceae (Gramineae). |
|
glandular 1 |
|
architecture |
|
Having one or more glands. |
|
coleorhiza |
|
STRUCTURE |
|
A sheath-like structure enclosing the radicle (embryonic root) in an embryo; esp. in Poaceae (Gramineae). |
|
prismatic |
|
solid shape |
|
Uniformly polygonal in transverse section, basally and apically truncate, all faces essentially plane. |
|
collar 1 |
|
STRUCTURE |
|
The free portion (if any) of a floral tube, distal to its casing and/or neck when one or both is/are present. |
|
pyxis pl. pyxides |
|
nominative |
fruit |
Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. |
|
hypocotyl |
|
STRUCTURE |
|
That portion of an embryo axis between the level of cotyledon insertion above and the root meristem (or radicle, if present) below. |
|
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
|
anchoring |
|
habit |
trichome |
Serving as a means of attachment to some external support. |
|
sellaeform |
|
solid shape |
|
See selliform. |
|
apotropous |
|
orientation |
ovule |
Anatropous but the whole recurved such that the raphe (adnate portion of the funiculus) faces the ovary wall (placenta) and the ovule is parallel to it, the micropyle facing the free basal portion of the funiculus. |
|
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
|
leaf scar |
|
FEATURE |
|
A scar on a twig or stem due to abscission of a megaphyll; having an outline like that of a transverse section through the base of the petiole, sheath, or blade that was inserted there. |
|
basicaulous |
|
insertion |
|
At or very near the stem base. |
