cane |
< culm, stem |
STRUCTURE |
|
A woody, aboveground culm. Use of this term or culm instead of stem is a matter of tradition and preference, not of descriptive precision or necessity. |
|
cancellate |
= clathrate, latticed |
architecture |
foliaceous structure |
Having portions of the blade naturally devoid of any but vascular tissue, which forms an open lattice in those areas. |
|
canaliculate |
= channeled |
solid shape |
|
Having a longitudinal, transversely rounded depression; esp. a petiole or petiolule. |
|
canalicular |
|
insertion |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
canalicular |
|
position |
|
Upon or otherwise directly associated with the channel of a petiole or petiolule. |
|
campylotropous |
|
orientation |
ovule |
Having the (reniform) ovule curved toward the ovary wall, the micropyle facing the wall, and the funiculus attached near the center of the concave side, the curvature and displacement of funicular insertion due to asymmetrical growth during ontogenesis. |
|
campylodromous |
|
venation |
|
Having several primary and/or strongly developed secondary veins that diverge from a point or small area near the base of the blade and run thence ultimately toward the apex, recurving proximally, arcuate and converging distally, reaching the apex or not. |
|
campanulate |
= bell-shaped |
solid shape |
|
Circular in transverse section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
calyx tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a synsepalous (gamosepalous) calyx proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the sepals. |
|
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
|
calyptriform |
|
solid shape |
|
Hollow, roughly circular in cross-section, broader and open distally, and tapering to a closed apex, like a candle snuffer or elongate hood. |
|
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
|
calyptra pl. calyptrae |
|
STRUCTURE |
|
A distal hood- or lid-like portion that detaches as a unit from the remainder of the structure; esp. in some Papaveraceae the unopened calyx that separates from the rest of the flower at anthesis. |
|
calyculus 2 pl. calyculi |
|
STRUCTURE |
|
Collectively the bractlets (bracteoles) sometimes subtending (beneath or outside) the involucre in a capitulum (head); in Asteraceae (Compositae). |
|
calyculus 1 pl. calyculi |
= epicalyx |
STRUCTURE |
|
A whorl of bracts immediately subtending (beneath or outside) a calyx; literally, a little calyx. |
|
calyculate 2 |
|
architecture |
flower |
Subtended by a calyculus (epicalyx). |
|
calyculate 1 |
|
architecture |
capitulum (head) |
With the involucre subtended by a calyculus; in Asteraceae (Compositae). |
|
calyciform |
= cup-shaped, cupulate |
solid shape |
|
Truncate-globose with the distal margin more or less entire; like the bowl of a cup. |
|
callus |
|
FEATURE |
|
A small, relatively hard covering, outgrowth, or swelling of tissue; esp. in axes of grass (Poaceae) inflorescences just distal to points of eventual disarticulation. |
|
callous |
= callose |
texture |
|
Hard-leathery; callous tissue usually is also thicker than comparable adjacent tissue. |
|
callose |
= callous |
texture |
|
Hard-leathery; callose tissue usually is also thicker than comparable adjacent tissue. |
|
calceolate |
= slipper-shaped |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
|
calcarate |
= spurred |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
caespitose |
|
habit |
|
See cespitose. |
|
caesious |
< ceraceous, cereous, pruinose, waxen, waxy |
coating |
|
Greenish pruinose; covered with a thin, opaque, greenish deposit (bloom) of macroscopically indistinguishable waxy particles that rubs off easily. See also glaucescent, glaucous. |
