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. |
|
waxen 1 |
= ceraceous, cereous, waxen; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
|
androgynophore |
< stalk |
STRUCTURE |
|
A stalk that rises above the level of perianth insertion and bears the free portions of both androecium and gynoecium from its summit; as in Passifloraceae. |
|
barb 2 |
|
STRUCTURE |
|
A trichome terminated by one or two small, relatively short, stiff, sharp, acutely reflexed appendages. |
|
microsporophyll |
> cone scale |
STRUCTURE |
|
A sporophyll that bears only microsporangia. |
|
campanulate |
= bell-shaped |
solid shape |
|
Circular in transverse section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
oleaginous 1 |
= greasy, oily, unctuous |
coating |
|
Of a grease- or oil-like film. |
|
pseudoaxillary |
|
position |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
|
dot-like |
= punctiform |
plane shape |
|
Very small and generally circular in outline. |
|
rigent |
= rigid, stiff |
texture |
|
Strongly resisting deformation over its length. |
|
septal |
|
position |
|
Upon or otherwise directly associated with the septum or septa. |
|
furrow |
= colpus, fossula, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
translator arm |
= caudicle |
STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
vernation |
|
CHARACTER |
|
Disposition of leaves in the bud. |
|
alate 1 |
= winged |
architecture |
|
Having one or more elongate, relatively thin protrusions or appendages that resemble wings. |
|
asymmetric(al) 1 |
|
architecture |
|
Not divisible into essentially equal halves along any line or plane. |
|
maturation |
|
CHARACTER |
|
Timing of the attainment of functional maturity, sometimes relative to other structures, sometimes as to constituent structures relative to each other. |
|
bulblet |
= bulbil |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
|
oblate |
|
plane shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
|
pellucid |
= hyaline; > translucent, transparent |
coloration |
|
Transmitting light uniformly. |
|
craspedodromous, mixed- |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
|
discal |
|
insertion |
|
Upon or otherwise directly associated with the floral disc. |
|
replum pl. repla |
< dissepiment, septum |
STRUCTURE |
|
The persistent wall or partition that separates the two locules of a silicle or silique. |
|
erose 2 |
= eroded |
relief |
|
Appearing as if chewed or gnawed; having very irregular localized deviations from its generalized line. |
|
second glume |
|
STRUCTURE |
|
The upper (distal) member of a pair of small bracts inserted at the base of a grass (Poaceae) spikelet. |
