…colporate |
|
architecture |
pollen grain |
Having the number of colpi indicated by the prefix, each containing a pore; as in dicolporate, 3-colporate. |
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
channel |
|
FEATURE |
|
A longitudinal, transversely rounded depression; esp. along the adaxial surface of a petiole or petiolule. |
ramal |
|
position |
|
Upon or otherwise directly associated with the stem branches. |
course |
|
CHARACTER |
|
Linear pattern of the centerline through the length of an axis or vein. |
spicule |
|
STRUCTURE |
|
A small, fine, stiff, acute protrusion that resembles a little spike. |
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). |
suprabasal |
|
insertion |
|
Just above the base of the structure in point. |
hip |
|
nominative |
fruit |
Aggregate and consisting of several to many achenes enveloped by a free, urceolate, more or less fleshy, accessory structure derived from floral tube tissue; esp. in Rosa (Rosaceae). |
replicate |
|
vernation |
|
Each with the distal portion of its blade recurved, paralleling and contiguous with the proximal portion. |
cryptocotyloid |
|
germination |
seed |
Having the cotyledon(s) remaining inside the seed coat. |
stephanocolporate |
|
architecture |
pollen grain |
Stephanocolpate, each groove containing a pore. |
resin |
|
SUBSTANCE |
|
A substance of high molecular weight consisting of organic acids, esters, and/or terpenes, produced within plant tissue and exuded from wounds as a liquid that hardens to an amorphous glassy state upon exposure. |
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
unequal |
|
size |
equivalent structures |
Distinctly differing in extent. See also equal, subequal. |
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
fluted |
|
solid shape |
|
Having rounded to angular longitudinal grooves. |
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
faceted |
|
solid shape |
|
Having numerous, relatively small, flat or shallowly curved portions of the external surface that are bounded by more or less distinct angular discontinuities in that surface. |
tuber |
|
STRUCTURE |
|
An enlarged, basically subterranean stem segment or thallus outgrowth containing a high proportion of storage tissue and functioning as a perennating and often vegetatively propagative structure. |
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. |
deliquescent 2 |
|
texture |
|
Delicately fleshy and liquifying at maturity or with pressure; e.g., petals of Tradescantia (Commelinaceae). |
vascular |
|
position |
|
Upon or otherwise directly associated with the vasculature. |
beard |
|
STRUCTURE |
|
A growth of relatively long, erect, flexible, capillary trichomes from one or more limited sectors of a structure's surface. |
floral |
|
position |
|
Upon, within, or associated with the flowers. |
