|
epiphyllous |
|
position |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
|
naked 1 |
|
architecture |
|
Lacking a covering that might have been expected. |
|
rhipidiate |
|
architecture |
inflorescence |
Comprising one or more rhipidia. |
|
biennial 1 |
|
duration |
plant, stem |
Normally living two years; germinating or forming and growing vegetatively during one cycle of seasons, then reproducing sexually and dying during the following one. |
|
winter annual |
|
nominative |
plant |
Annual, germinating in autumn, overwintering in a vegetative state (usually as a rosette aboveground), reproducing sexually from early spring through summer, and dying promptly thereafter. See also summer annual. |
|
explosive |
|
dehiscence |
|
Opening abruptly with almost instantaneous aperture formation and release of accumulated structural tensions, the contents thus forcibly expelled. |
|
non-septate |
|
architecture |
trichome |
Lacking transverse inter- or intracellular septa or partitions. |
|
cuspidate |
|
apex |
|
Tapering gradually to a rigid tip composed of both vascular and laminar tissues. |
|
lenticel |
|
STRUCTURE |
|
A specialized, anatomically distinct structure within the periderm of a stem, consisting of comparatively spongy, sometimes suberized tissue distinct from others of the periderm; extending radially through the periderm and visible as a circular to elongate discontinuity in the color, texture, and/or relief of the outer surface of the stem; serving as a conduit for gas exchange between the stem interior and the atmosphere. |
|
polyadal |
|
arrangement |
pollen |
Shed in groups of more than four, each group comprising grains from two or more original tetrads, the latter intact or not. |
|
alternate 1 |
|
arrangement |
|
Inserted singly along the axis, each at a different level and each diverging on a different radius than the ones next above and below. |
|
sap |
|
SUBSTANCE |
|
Generally, the fluid content of a plant body; more precisely, the sugary fluid transported by the phloem. |
|
deliquescent 2 |
|
texture |
|
Delicately fleshy and liquifying at maturity or with pressure; e.g., petals of Tradescantia (Commelinaceae). |
|
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
|
fixed |
|
fixation |
|
Attached to the bearing structure in a manner allowing no significant rotation or declination in relation to it. |
|
angled |
|
solid shape |
|
Having sides that meet at acute or obtuse angles. |
|
opaque |
|
coloration |
|
Not transmitting light. |
|
scarious |
|
texture |
|
Very thin, dry, and not green. |
|
stilt-rooted |
|
architecture |
plant |
Bearing and partly supported by stilt roots. |
|
hypogynous |
|
insertion |
perianth, calyx, corolla, androecium |
Entirely free from the gynoecium or any floral cup, arising from a level proximal or lateral to the base of the gynoecium. See also epigynous, perigynous. |
|
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
|
strobiloid |
|
architecture |
flower |
Characterized by a general lack of adnation among the different sets of basic floral structures, any significant degree of fusion limited to connation within sets, thus with ovary(ies) superior and lacking a floral tube. |
|
column 2 |
|
STRUCTURE |
|
A fused androecium (connate stamens) closely surrounding but free from the gynoecium; esp. in Malvaceae. |
|
inflated |
|
solid shape |
|
Relatively thin-walled with an essentially empty interior largely enclosed by the walls, which are convex overall and appear taut, as though from internal pressure. See also swollen (turgid, tumid), which is not clearly distinct in its application. |
|
duration |
|
CHARACTER |
|
Extent of lifetime, or persistence and physical state after maturation. |
