|
corneous |
= horny |
texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |
|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
galea pl. galeae, galeas |
|
STRUCTURE |
|
A galeate (galeiform, helmet-shaped) sepal or petal in a zygomorphic calyx or corolla, differing markedly in shape from and sometimes partially enclosing the other sepals or petals. |
|
petiolule |
< stalk |
STRUCTURE |
|
The stalk, when present, of a leaflet, analogous to the petiole of a leaf. |
|
theca pl. thecae |
= pollen sac |
STRUCTURE |
|
Any of the one, two or four ontogenetically distinct, pollen-producing sectors (microsporangia) of an anther. In some taxa the walls between pairs of adjacent thecae break down as an anther approaches maturity, the mature anther thus ultimately containing half as many locules as thecae. |
|
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. |
|
sausage-shaped |
= botuliform |
solid shape |
|
Arcuately cylindric with rounded ends. |
|
opposite 2 |
|
arrangement |
|
Having the members of each whorl inserted directly above and/or below those of the next adjacent whorl(s). See also antipetalous, antisepalous. |
|
squamule 2 |
= squamella; < scale |
STRUCTURE |
|
A small, dry bract borne on the compound receptacle (torus) of a capitulum (head); in Asteraceae (Compositae). |
|
primary root |
> taproot |
STRUCTURE |
|
The one, central root directly basal to a shoot, developing directly from the embryonic radicle; the first-formed root of a plant, being the only one truly central in nature (i.e., belonging to the original central axis of the plant). All other roots of a plant develop subsequently and are lateral in nature. The primary root may be permanently dominant, developing into a taproot; otherwise it may be transitory or become functionally subordinate, with secondary and/or adventitious roots becoming dominant. |
|
lorate |
= liguliform, strap-shaped |
solid shape |
|
Elongate and relatively thin with the opposite faces more or less plane and moderately narrow, their edges more or less straight and parallel over most of their length; resembling a strap. |
|
cone scale |
< macrosporophyll (not recommended), megasporophyll, microsporophyll; > ovuliferous scale |
STRUCTURE |
|
One of the membranous, fleshy, or woody sporophylls of a cone (strobilus); esp. in Pinophyta. |
|
fovea pl. foveae |
= pit, scrobis |
FEATURE |
|
A small, rounded depression. |
|
setaceous |
= bristle-shaped, setiform |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
|
dome-shaped |
= tholiform |
solid shape |
|
Convex overall, broadest at the base, and transversely more or less circular to elliptical throughout. |
|
knee 1 |
|
STRUCTURE |
|
An abrupt bend in an axial or other elongate structure. |
|
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. |
|
mucilaginous 1 |
= mucous; < glutinous |
coating |
|
Of a slimy substance, or becoming so upon wetting. |
|
viscid 1 |
< glutinous |
coating |
|
Of a sticky substance. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
bell-shaped |
= campanulate |
solid shape |
|
Circular in cross-section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
viscid 2 |
< glutinous |
texture |
|
Sticky. |
|
bellied |
= ventricose |
solid shape |
|
Bulging unilaterally near the middle, as though with a belly. |
|
gummy |
|
texture |
|
Highly viscous and sticky, liquid or more or less deformably solid, sometimes more or less elastic. |
|
spiral 1 |
= acyclic, helical |
arrangement |
|
Disposed helically about and along the axis, each on a different radius than the one(s) vertically adjacent. |
