|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
|
one-sided 1 |
= unilateral |
architecture |
|
Having only one side, as compared with presumably equivalent, bilaterally symmetric structures. |
|
coloration |
|
CHARACTER |
|
Hue(s), intensity(ies), and/or pattern (if any) of coloring. When more than one hue and/or intensity is involved, a term describing the pattern of contrast will be applicable, and the description as a whole should be phrased to indicate the particular role of each in the pattern; e.g., "ovaries striate, yellow on green"; "petals pink, spotted yellow basally"; "sepals green, suffused with red". |
|
petiolar |
|
insertion |
|
Upon or otherwise directly associated with the petioles. |
|
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. |
|
pseudostem |
|
STRUCTURE |
|
A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
|
downy |
= pubescent |
pubescence |
|
Of or bearing relatively short, slender, soft, more or less erect, capillate trichomes. See also puberulent. |
|
seriate |
= cyclic, 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. |
|
galeate |
= galeiform, helmet-shaped |
solid shape |
|
Convex overall with a more or less smoothly curved apex, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a helmet. See also cucullate (cuculliform, hood-shaped), which overlaps conceptually. |
|
squamella 1 pl. squamellae |
= squamule; < scale, trichome |
STRUCTURE |
|
A diminutive squama (lepis). |
|
vesicle |
|
STRUCTURE |
|
A small bladder-like part consisting of an enclosing wall or covering and an empty or fluid-filled interior, sometimes turgid; esp. in citrus fruits (hesperidia). |
|
almondy |
= hydrocyanic |
odor |
|
Pungently fruity like almonds, due to the presence of hydrocyanin or a closely related compound. |
|
attenuate 2 |
= tapered |
solid shape |
|
Gradually diminishing in breadth or diameter from one end to the other. |
|
medullose |
= pithy |
texture |
|
Loose or spongy internally, denser and firmer externally. |
|
bundle scar |
|
FEATURE |
|
A smaller scar within the bounds of a leaf scar at the point where a vascular bundle traversed the abscission layer between stem and leaf. |
|
obovate |
|
plane shape |
|
Inversely ovate (egg-shaped). |
|
clavate |
= club-shaped |
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. |
|
…crenate |
= …-scalloped |
margin |
|
Having the number of orders of crenae (scallops) indicated by the prefix, one upon another; as in bicrenate, twice-crenate. See also …dentate (…-toothed), …serrate (…-sawtoothed). |
|
primary stem |
= main stem; > bole, trunk |
STRUCTURE |
|
The one, or any of the more than one, first-order stem(s), or first-order portion(s) of the collective stem, of a shoot. |
|
reticulate 2 |
= netted |
coloration |
|
Having a pattern of interconnected fine lines of contrasting hue and/or intensity. |
|
exalate 1 |
= wingless |
architecture |
|
Lacking elongate, relatively thin protrusions or appendages that resemble wings. |
|
seed coat |
= testa |
STRUCTURE |
|
The outer protective layer of a seed, developed from the ovular integument(s). |
|
foveolate |
= fine-pitted, scrobiculate |
relief |
|
Finely foveate (pitted). |
|
spinose 2 |
= echinate, spiny |
architecture |
|
Bearing spines. See also spinulose. |
|
headed 2 |
= capitate |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
