acephalous 1 |
= headless |
architecture |
|
Not terminated or surmounted by a head-like structure, esp. when one might be expected. |
unilateral 1 |
= one-sided |
architecture |
|

neck (floral tube) |
|
STRUCTURE |
|
The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
fusiform |
= spindle-shaped |
solid shape |
|
Elongate, transversely round, broadest at the middle and regularly attenuate to either end. |
declined |
= inclined |
orientation |
|
Directed downward or backward. |
club-shaped |
= clavate |
solid shape |
|
Elongate and basically round in transverse section, the diameter greatest at or near a blunt apex, thence attenuate toward the base, the degree of taper greatest between the middle and the upper quarter. |
petiole |
< stalk, stipe (broad sense, not recommended) |
STRUCTURE |
|
The stalk, when present, of a leaf. |
laminar 1 |
|
position |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
distant |
= remote |
arrangement |
|
Disposed relatively far from one another along the axis. |
thallus 1 pl. thalli |
|
STRUCTURE |
|
The vegetative portion of a shoot when not differentiated into stem and leaves; esp. in Lemnaceae. |
sarcous |
= carnose, fleshy |
texture |
|
Fairly firm and dense, juicy or at least moist, and easily cut. |
conjugate |
= geminate, paired |
arrangement |
|
Inserted by pairs, the members of each fused or not. |
calyculus 2 pl. calyculi |
|
STRUCTURE |
|
Collectively the bractlets (bracteoles) sometimes subtending (beneath or outside) the involucre in a capitulum (head); in Asteraceae (Compositae). |
operculum pl. opercula |
= lid |
STRUCTURE |
|
A distal, cover-like portion of a structure whose main body is otherwise closed, transversely discontinuous with the main body around most of the circumference, or becoming partially or wholly separate by transverse dehiscence; as of an ascidium (pitcher), pollen grain, pyxis, or sporangium (spore case). |
squamose |
= lepidote, squamate; < scaly |
pubescence |
|
Bearing squamae (lepides). See also squamellose. |
opposite 1 |
|
arrangement |
|
Disposed in pairs along the axis, the members of each pair inserted at the same level across from one another. |
squamule 1 |
= squamella; < scale |
STRUCTURE |
|
A diminutive squama (lepis). |
arrowhead-shaped 2 |
= sagittate |
plane shape |
|
Generally triangular, tapering gradually from the base to an acute apex, the base with a relatively large, acute, retrorse lobe to either side; like the outline of the broad lateral face of an arrowhead. |
primary axis |
> ray |
STRUCTURE |
|
A main or first-order axis within any specified, uniformly delimited structural context. |
loose 2 |
|
texture |
|
Soft overall, discontinuously and only weakly cohesive. |
four-… |
= quadr(i)…, tetra… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in four-angled, four-petaled, four-ranked. |
archegonium pl. archegonia |
|
STRUCTURE |
|
A female gametangium; a multicellular fertile organ of a mature gametophyte within which female gametes (eggs, ova) are produced and fertilized; having a broad, bulbous base and a narrower distal neck. Technically present but highly reduced and of no descriptive significance in Magnoliophyta. |
seta 2 pl. setae |
= bristle; > glochid, glochidium |
STRUCTURE |
|
A trichome that is elongate, slender, more or less straight, terete, fine-pointed, and stiff. |
culm |
< cane, stem |
STRUCTURE |
|
A stem of a sedge (Cyperaceae) or grass (Poaceae), usually hollow. Use of this term or cane instead of stem is a matter of tradition and preference, not of descriptive precision or necessity. |
