groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
spinulose |
|
apex |
|
Finely spinose. |
arching |
= recurved |
orientation |
|
Curving backward or downward. |
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. |
checkered 2 |
= tessellate |
relief |
|
Having a pattern of regularly disposed squares marked by raised or depressed vasculature. |
rough 1 |
= scabrous |
pubescence |
|
Of or bearing coarse, stiff, ascending, trichomes and markedly rough to the touch. |
acropetal |
|
development |
|
Proceeding toward the apex, thus more advanced basally or proximally than apically or distally within a given frame of reference. |
flexuose |
|
course |
|
See flexuous. |
declined |
= inclined |
orientation |
|
Directed downward or backward. |
obturbinate |
|
solid shape |
|
Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
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. |
beaklet 1 |
= rostellum |
STRUCTURE |
|
A small beak or rostrum. |
pungent 1 |
= acrid |
apex |
|
Terminating abruptly in a rigid, relatively short, sharp point composed of both vascular and laminar tissues. |
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
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. |
dot-like |
= punctiform |
plane shape |
|
Very small and generally circular in outline. |
intravaginal |
|
position |
|
Within the leaf sheath. |
suture |
|
FEATURE |
|
An evident line of ontogenetic union. |
epipetalous |
|
insertion |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
rhomboid |
= diamond-shaped |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
cucullus pl. cuculli |
= hood |
STRUCTURE |
|
A cucullate (cuculliform) structure or component, esp. in an inflorescence or flower. |
nucellus pl. nucelli |
|
STRUCTURE |
|
The distinct, genetically diploid tissue layer immediately surrounding the embryo sac of an ovule; often considered equivalent to a megasporangium wall. |
