headless 2 |
= acephalous |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
pinnatifid |
> pinnatisect; < pinnate |
solid shape |
|
Pinnately divided. |
diamond-shaped |
= rhomboid |
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. |
laticiferous |
|
exudation |
|
Producing and exuding latex. |
tiller |
|
STRUCTURE |
|
An erect or ascending stem that branches from the base of another at or below the surface of the ground; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
scale-like |
= squamiform |
solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
collar 2 |
|
FEATURE |
|
The junction between the sheath and blade of a leaf; esp. in Poaceae (Gramineae). |
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
staminal |
|
insertion |
|
Upon or otherwise directly associated with the stamens. |
inclined |
= declined |
orientation |
|
Directed downward or backward. |
prophyll(um) pl. prophylls, prophylla |
= bracteole, bractlet; < bract |
STRUCTURE |
|
A second- or higher-order bract within, and subtending some portion of, an aggregate branching structure, especially when subtending a flower. |
eight-… |
= octa… |
prefix |
|
Indicating presence of or constitution by eight entities of the type denoted by the term's stem; as in eight-carpelled, eight-flowered, eight-stamened. |
maculate |
= blotched, spotted |
coloration |
|
Having one or more areas that differ in color from the rest of the surface. See also eyespotted. |
canescent |
= hoary |
pubescence |
|
Densely covered with gray, fine, relatively short, capillate trichomes. |
shoot 2 |
|
STRUCTURE |
|
A vascularized axis that is differentiated into nodes and internodes and that branches exogenously from the former, together with any non-axial structures borne from it. |
albumen |
= endosperm |
STRUCTURE / SUBSTANCE |
|
A genetically triploid (3n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from fusion of the two polar nuclei (n + n chromosomes) of the embryo sac with a sperm nucleus from the pollen tube (n chromosomes). See also perisperm. |
coronal |
|
insertion |
|
Upon or otherwise directly associated with the corona. |
lacerate |
= cut, incised, torn; > laciniate, slashed |
plane shape |
|
Having straight to irregular lines of separation extending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
terminal |
|
position |
|
Apical and with the same developmental axis as the whole, of which it is the distalmost portion or appendage. |
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
S-shaped 1 |
= sigmoid |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |
muscariform |
= broom-shaped, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |
cladophyll |
= cladode, phylloclade |
STRUCTURE |
|
A stem segment that functions as a leaf; often more or less compressed. |
