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. |
squamule 3 |
= lodicule, squamella |
STRUCTURE |
|
One of two or three small, scale-like structures inserted at the base of the androecium, distal to the palea, in most grass (Poaceae) flowers; often regarded as a vestigial branch or perianth member. |
astomatiferous |
= non-stomate-bearing |
architecture |
|
Lacking stomates in the epidermis. |
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. |
lumen pl. lumina |
|
FEATURE |
|
A space enclosed by the wall(s) or membrane(s) of a structure. |
…celled |
= …cellular |
architecture |
|
Having the number of cells indicated by the prefix; as in one-celled, few-celled, 5-celled. |
two-… |
= bi…, di… |
prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in two-cleft, two-flowered, two-loculed. 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; and also double-… (bi…, twice-…). |
foveate |
= pitted |
relief |
|
Having numerous, small, rounded depressions. See also foveolate (fine-pitted, scrobiculate). |
setiform |
= bristle-shaped, setaceous |
solid shape |
|
Elongate, slender, terete, straight, terminating in a fine point, and apparently stiff; like a bristle. |
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
subopposite |
|
arrangement |
|
Alternate but verging on opposite. |
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
bole |
= trunk; < main stem, primary stem |
STRUCTURE |
|
The relatively stout, columnar, main stem of a distinct aboveground portion of a tree. |
mucilaginous 2 |
= mucous; < glutinous |
texture |
|
Slimy. |
column foot |
= mentum |
STRUCTURE |
|
A lateral, often nectariferous protrusion from the proximal portion of a column, opposite the labellum, projecting in front of the rest of the flower; in Orchidaceae. |
viscid 2 |
< glutinous |
texture |
|
Sticky. |
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. |
pollen sac |
= theca |
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. |
limp |
|
texture |
|
Lacking stiffness in in one or more dimensions, thus drooping or sagging where unsupported. |
carina 1 pl. carinae |
= keel |
STRUCTURE |
|
An elongate, median longitudinal ridge that is basically triangular in transverse section and resembles the keel of a boat; esp. in leaf blades and sheaths, glumes, lemmata, paleae, sepals, petals. |
trulliform |
= trowel-shaped, trullate |
plane shape |
|
Broadest below the middle, more or less straightly attenuate to either end, the sides angled at the level of greatest width; like the blade of a mason's trowel. See also obtrullate, obtrulliform. |
ocellate |
= eyespotted |
coloration |
|
Having a more or less circular area that differes in hue and/or intensity from the remainder of the structure; esp. a corolla with such an area at its center. |
crest |
= crista |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
hood-shaped |
= cucullate, cuculliform |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also helmet-shaped (galeate, galeiform), which overlaps conceptually. |
