tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
pericolpate |
|
architecture |
pollen grain |
Having more than three surficial grooves (colpi) oriented such that some or all of them cross meridians. |
vernation |
|
CHARACTER |
|
Disposition of leaves in the bud. |
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
coherent |
|
fusion |
equivalent structures |
Joined superficially, with no significant histological continuity. |
floral |
|
position |
|
Upon, within, or associated with the flowers. |
pseudostem |
|
STRUCTURE |
|
A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
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. |
actinodromous |
|
venation |
|
Having three or more primary veins that diverge radially from a point at or above the base of the blade and run toward the margin, reaching it or not. |
sellaeform |
|
solid shape |
|
See selliform. |
androgynous |
|
reproduction |
taxon |
Monoecious, each inflorescence having a distal sector with only staminate flowers and a proximal sector with only pistillate ones. |
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
connate |
|
fusion |
equivalent structures |
Intimately fused, with strong histological continuity. |
simple 2 |
|
architecture |
trichome |
Unicellular and unbranched. |
connate-perfoliate |
|
architecture |
opposite laminar structures |
Having the bases in each pair fused and together encircling the bearing axis. See also amplexicaulous, perfoliate. |
spinulose |
|
apex |
|
Finely spinose. |
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
coronal |
|
insertion |
|
Upon or otherwise directly associated with the corona. |
deciduous 1 |
|
duration |
structure |
Separating and falling away from the bearing axis, organ or plant prior to senescence of the latter, usually by developing an anatomically distinct, transverse, basal zone of cells (abcission layer), where separation occurs. See also seasonally deciduous. |
oblate |
|
plane shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
tertiary vein |
|
STRUCTURE |
|
A strand belonging to the third order of vasculature in a leaf or other basically laminar structure, except when that is the ultimate order (consisting of veinlets); branching from a primary or secondary vein. See also costa, lateral vein, primary vein, rib, secondary vein, veinlet. |
