A cyme with the main axis markedly shorter than the lateral axes, appearing generally paniculate when compound; esp. in Juncaceae. |
|
adventitious bud |
|
STRUCTURE |
|
A vegetative or floral bud that arises directly from a root or from some site on a shoot other than a leaf axil or stem apex. |
|
embryo |
|
STRUCTURE |
|
The rudimentary spermatophyte contained within a viable seed. |
|
symmetric(al) 1 |
|
plane shape |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
obturbinate |
|
solid shape |
|
Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
|
pseudostem |
|
STRUCTURE |
|
A structure that resembles a stem but is not part of the axial system of a shoot, lacking anatomical differentiation into nodes and internodes. |
|
knee 2 |
|
STRUCTURE |
|
An emergent portion of an otherwise normally submerged secondary root of a wetland tree, resembling a bent human knee. |
|
contiguous |
|
arrangement |
|
Touching one another. |
|
appressed |
|
orientation |
lateral structure |
Angled at or near the base and closely flattened against the surface of the bearing structure, thus more or less parallel to it. |
|
epipetalous |
|
position |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
tepal |
|
STRUCTURE |
|
Any member of an undifferentiated perianth; may be green and foliaceous or colored and petaloid, distinct or else connate with one or more others, and/or free or else adnate with one or more other floral structures. |
|
spikeleted |
|
architecture |
inflorescence |
Having the penultimate subdivisional order consisting of spikelets. |
|
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
|
fruit |
|
STRUCTURE |
|
Any unitary seed-bearing structure of a flowering plant, consisting of the matured or ripened pistil(s) of one or more flowers along with any other floral or vegetative tissue(s) persisting adnate to them; characteristic of and unique to Magnoliophyta (Angiospermae). |
|
pyxis pl. pyxides |
|
nominative |
fruit |
Like a capsule but circumscissile, the one or more seeds being released from the locule(s) upon separation of the distal, cap-like portion of the pericarp. See also diplotegium. |
|
circumcaulous |
|
position |
|
Upon and surrounding the stem. |
|
raphe |
|
STRUCTURE |
|
That portion of the funicle adnate to the integument of an anatropous ovule; represented by a longitudinal ridge or other discontinuity in the surface and/or color of the testa on one side of the mature seed. |
|
levering |
|
habit |
trichome |
Forming part of a pappus and reflexing at maturity, thus helping to loosen the individual fruit (cypsela) from the capitulum (head); in Asteraceae (Compositae). |
|
stamen |
|
STRUCTURE |
|
A seed-plant organ that produces and releases pollen; usually comprising a stalk (filament) that bears a locular structure (anther) containing sporogenous tissue; however, the filament may be lacking and the anther sessile, or the stamen may be undifferentiated, the whole then consisting of microsporangia embedded in or borne upon the surface of a more or less planate body of sterile tissue; one of the constituent organs of a bisexual or a staminate flower; may be distinct or else connate with one or more others and/or may be free or else adnate with one or more other floral structures. |
|
scar |
|
FEATURE |
|
A discontinuity in surface color and/or relief due to abscission of a structure formerly borne there. |
|
meniscoid |
|
solid shape |
|
Relatively thin with opposite, round, broad faces, one convex and one concave (as viewed externally), the circumferential edge angular or rounded; like a meniscus. See also discoid (disciform), lenticular (biconvex, lens-shaped), patelliform (kneecap-shaped). |
|
scarious |
|
texture |
|
Very thin, dry, and not green. |
|
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
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. |
