Elongate, basically triangular in transverse section, tapering at one or both ends, the outer edge thus somewhat arcuate, the whole resembling the keel of a boat. |
|
dusty |
= lentiginose, lentiginous |
coating |
|
Covered with a more or less even deposit of minute, dry, macroscopically indistinguishable particles. See also powdery (pulverulent), which is not clearly distinct in its application. |
|
ramal |
|
insertion |
|
Upon or otherwise directly associated with the stem branches. |
|
aseptate |
|
architecture |
|
Lacking internal walls or partitions (septae). |
|
motile |
|
habit |
|
Able to translocate by intrinsic means, as by flagellar propulsion. |
|
villous |
= shaggy, villose |
pubescence |
|
Bearing sparse, long, slender, soft, capillate trichomes that are not intertwined. See also villosulous. |
|
cauline |
|
position |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
|
spinulose |
|
apex |
|
Finely spinose. |
|
cyclic |
= seriate, verticillate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted around the axis at the same level. |
|
plumule |
= epicotyl |
STRUCTURE |
|
A distinguishable nascent shoot developed in the embryo in some taxa, consisting of a shoot axis with unexpanded internodes and one or more leaf primordia, being that portion of the embryo above the level of cotyledon insertion; the primordial shoot, when developed by the embryo within a seed; the first bud of a spermatophyte, when developed by an embryo within the seed. In other taxa the shoot is represented in the embryo only by a quiescent apical meristem at the summit of the embryonic axis. |
|
rough 1 |
= scabrous |
pubescence |
|
Of or bearing coarse, stiff, ascending, trichomes and markedly rough to the touch. |
|
blunt 1 |
= obtuse |
apex |
|
Bluntly angular; having an angular tip whose generalized sides intersect at an angle of 90° or more. |
|
flexuose |
|
course |
|
See flexuous. |
|
obturbinate |
|
solid shape |
|
Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
|
columella 2 pl. columellae, columellas |
= carpophore; < stalk |
STRUCTURE |
|
The stalk supporting a mericarp after dehiscence of a schizocarpic fruit, the central axis of the fruit having split longitudinally to yield two or four such stalks; composed of receptacular and (primarily) gynoecial tissues; esp. in Apiaceae (Umbelliferae). |
|
homomorphic |
> homocladic, homophyllous, homostylous |
architecture |
|
Occurring in only one form within the taxon in point. |
|
stomatal pore 2 |
= stomium |
FEATURE |
|
The opening in the wall of a sporangium, between the lip cells, through which the spores exit; in Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta. |
|
pungent 1 |
= acrid |
apex |
|
Terminating abruptly in a rigid, relatively short, sharp point composed of both vascular and laminar tissues. |
|
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
|
selliform var. sellaeform |
= saddle-shaped |
solid shape |
|
Relatively thin, broad and long, strongly compound-curved, concavely from end to end and convexly from side to side; like the generalized shape of a saddle. |
|
glandless |
= eglandular |
architecture |
|
Lacking glands. |
|
crowded |
= compact, congested |
architecture |
|
Having equivalent constituent parts disposed very near to one another. |
|
intravaginal |
|
position |
|
Within the leaf sheath. |
