Broadly obovoid-obconic; like a spinning top. See also pear-shaped (pyriform), obturbinate. |
|
filiform |
= thread-like |
solid shape |
|
Elongate and very slender, basically round in transverse section and of more or less uniform diameter, variously curved over its length or not. See also capillary (capillate, hair-like). |
|
bracteole 2 |
= bractlet, prophyll(um); < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
|
palea 2 pl. paleae, paleas |
= pale, palet |
STRUCTURE |
|
The distal bract of the (usually) two that immediately subtend the flower in a grass (Poaceae) spikelet; the other is the lemma. |
|
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
|
subulate 2 |
= awl-shaped |
solid shape |
|
Slender, essentially terete, and straight, gradually attenuate from a relatively narrow base to a very narrow, blunt to angular apex. |
|
elliptic(al) 2 |
= oval |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
recurved |
= arching |
orientation |
|
Curving outward (abaxially), downward, or backward. |
|
many-… |
= multi…, pluri…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in many-angled, many-pistilled, many-seeded. See also few-… (oligo…). |
|
unguis pl. ungues |
= claw |
STRUCTURE |
|
The abruptly much narrower proximal portion, when present, of a laminar structure, esp. a petal; of variable shape itself, but usually attenuate toward the base. |
|
furcate |
= forked; > bifurcate |
apex |
|
Having two or more terminal, antrorse branches or divisions arising from a common point or level, like the prongs of a fork. |
|
carpophore 3 |
= columella; < 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). |
|
costa pl. costae |
= rib; > midnerve (not recommended), midrib, midvein; >< lateral vein |
STRUCTURE |
|
A primary vein of a laminar structure, having a longitudinal course, either medial or lateral, often prominent. See also secondary vein, tertiary vein, veinlet. |
|
aerial |
|
location |
|
Above ground or water level. |
|
base |
|
CHARACTER |
|
Configuration of the lowermost or proximal portion of a structure, its extent determined somewhat subjectively in relation to the shape of the structure as a whole. The concept of base varies from one descriptive context to another, since the base is not a clearly delimited, morphologically distinct entity. The terms for describing basal condition are not strictly coordinate logically — some are more inclusive than others, and some describe conditions involving what can be regarded as appendages — and precise characterization may require using more than one descriptor. The semantic antecedent of some descriptors is "base," whereas the antecedent of others is the structure as a whole (e.g., leaf ). |
|
lageniform |
= ampulliform, flask-shaped |
solid shape |
|
Generally circular in cross-section, broadest at or below the middle, approximately globose below that and constricted above to a relatively narrow neck; like a flask. |
|
tetra… |
= four-…, quadr(i)… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in tetrandrous, tetracarpellate, tetracolporate. See also individual entries for terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
|
farina pl. farinae, farinas |
|
SUBSTANCE |
|
A dry, meal- or flour-like covering. |
|
…whorled |
= …cyclic, …seriate, …verticillate |
arrangement |
|
Disposed in the number of whorls (cycles, series, verticils) indicated by the prefix; as in three-whorled, 1-whorled. |
|
one-sided 3 |
= unilateral |
insertion |
|
Upon or arising from one side only of the bearing structure. |
|
squamate |
= lepidote, squamose; < scaly |
pubescence |
|
Bearing squamae (lepides). See also squamellose. |
|
cochleate |
= snail-shell-shaped |
solid shape |
|
Relatively broad and short, basically round in transverse section, resembling a rapidly tapering spire overall, the exterior helically convoluted; like a snail shell. |
