absent |
|
presence |
|
Not occurring within the context in point. |
|
persistent |
|
duration |
structure |
Remaining attached and conspicuous until the bearing structure reaches maturity. |
|
vascular |
|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
|
zygomorphic |
|
architecture |
perianth, calyx, corolla |
Bilaterally symmetric; divisible into two essentially equal portions along only one median logitudinal plane. |
|
gynaecium |
|
STRUCTURE |
|
See gynoecium. |
|
resupinate |
|
orientation |
lateral structure |
Inverted due to twisting distal to the point of insertion during development. |
|
haustorium pl. haustoria |
|
STRUCTURE |
|
An absorbing and anchoring organ, often root-like, excrescent from a vegetative part of a parasitic or hemiparasitic plant, by which the plant communicates intimately with and derives sustenance and support from its host plant, into whose tissues the haustorium intrudes. |
|
rugulose |
|
relief |
|
Slightly or finely rugose (corrugate, wrinkled). |
|
hysteranthous |
|
maturation |
non-floral structure, esp. leaf |
Maturing later than the flowers. |
|
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
|
ringed |
|
relief |
bark |
Fissured, mainly horizontally, with at least some of the fissures individually encircling the stem more or less completely. |
|
intricate |
|
arrangement |
|
Entangled; irregularly intertwined and not readily disentangled. |
|
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. |
|
infrabracteal |
|
insertion |
|
Upon the axis directly below a bract insertion. |
|
laminar 1 |
|
insertion |
|
Upon or otherwise directly associated with the lamina (blade) of a foliaceous structure. |
|
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
|
knee root |
|
STRUCTURE |
|
A specialized secondary root of a wetland tree, a portion of which projects above mean water level and appears to bend as a leg does at the knee, its distalmost portion being anchored in the substrate beneath the water. The knee of the root is commonly regarded as a conduit for gas exchange between root interior and atmosphere, a function whose need is posited on the basis of the highly anaerobic and saturated conditions prevailing in wetland substrates. |
|
circumscissile |
|
dehiscence |
|
Splitting transversely through the exterior wall about its entire circumference, the resulting upper cap-like portion falling away. |
|
liguliflorous |
|
architecture |
capitulum (head) |
Bearing florets that all are bisexual and have zygomorphic corollas; in Asteraceae (Compositae). |
|
sinuous |
|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
|
continuous 3 |
|
architecture |
rachilla, rachis |
Not disarticulating at maturity. |
|
subequal |
|
size |
equivalent structures |
Nearly uniform in extent. See also equal, unequal. |
|
decussate |
|
arrangement |
|
Opposite with successive pairs radially oriented at right angles to one another, thus polystichous with four equidistant ranks. |
|
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. |
|
obovoid |
|
solid shape |
|
Inversely ovoid (egg-shaped). |
