cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
tomentulose |
|
pubescence |
|
Finely tomentose. |
epirhizal |
|
position |
|
Upon or arising from the roots. |
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). |
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. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
androgynecandrous |
|
reproduction |
taxon |
Monoecious, each inflorescence having distal and proximal sectors with only staminate flowers and between them a central sector with only pistillate ones. |
indusiate |
|
architecture |
sorus |
Having an indusium. |
laesura pl. laesurae |
|
FEATURE |
|
An elongate aperture in the proximal face of a spore at or near its pole, coterminous with a tetrad scar; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. Depending upon tetrad configuration and resultant scar pattern, a laesura may be either unbranched or branched, the branches when present (usually 3) radiating from the pole and of approximately equal lengths. |
solid shape |
|
CHARACTER |
|
Overall three-dimensional form or aspect(s) thereof. Overlaps conceptually with architecture, arrangement, habit, insertion, orientation, position, relief, and texture (as to thickness). |
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. |
axillary |
|
insertion |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
spinulose |
|
apex |
|
Finely spinose. |
location |
|
CHARACTER |
|
Position with respect to aspects of environmental context. |
coronal |
|
insertion |
|
Upon or otherwise directly associated with the corona. |
