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. |
corona pl. coronae, coronas |
> gynostegium |
STRUCTURE |
|
A crown-like set of connate or distinct appendages or enations borne upon a corolla or androecium or between them. |
planoconcave |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one concave. |
lepidote |
= squamose; < scaly |
pubescence |
|
Bearing lepides (squamae). See also squamellose. |
oblique 1 |
|
apex |
|
Asymmetric about its longitudinal axis. |
chewed |
= ruminate |
relief |
|
Irregularly convoluted, as if chewed. |
hexa… |
= six-… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in hexandrous, hexacarpellate, hexacolporate. |
stilt root |
|
STRUCTURE |
|
A relatively stout or strong adventitious root arising from a woody stem branch and extending downward directly toward the substrate, within which it ultimately becomes anchored, thus supporting the branch of origin; as in some Ficus (Moraceae). |
discal |
|
position |
|
Upon or otherwise directly associated with the floral disc. |
pubescent 1 (broad sense) |
|
pubescence |
|
Bearing trichomes. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
trichome |
> bristle, capillus, glochid, glochidium, hair, lepis, scale, seta, squama, squamella, squamule; >< cilium |
STRUCTURE |
|
Any superficial, unicellular or multicellular structure arising entirely from an epidermis. Unlike other epidermal enations or coverings, trichomes are cellular structures. |
medullose |
= pithy |
texture |
|
Loose or spongy internally, denser and firmer externally. |
flanged |
|
plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
papillar(y) |
= papilliform |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
supervolute |
|
vernation |
|
Each with one side rolled adaxially inward from the margin and enveloped by the abaxially rolled opposite side. |
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
valleculate |
= colpate, fossulate, furrowed, grooved, sulcate |
architecture |
|
Having one or more relatively narrow and shallow longitudinal depressions; esp. fruits of Apiaceae (Umbelliferae). |
bud scale |
|
STRUCTURE |
|
A scale that, alone or aggregated with others, envelops and protects a bud. |
nodal |
> interpetiolar |
insertion |
|
Upon or associated with the nodes. |
wrinkled |
= corrugate, rugose |
relief |
|
Having irregular, narrow ridges or creases, the intervening areas flat to shallowly concave or convex, appearing overall as though crumpled and then spread out. See also rugulose. |
small-sawtoothed |
= serrulate |
margin |
|
Finely sawtoothed (serrate). See also scalloped (crenate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
headless 2 |
= acephalous |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
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. |
