hypochilium |
|
STRUCTURE |
|
The proximal portion of a labellum (lip) that has distinct proximal, distal, and sometimes also central parts; in Orchidaceae. See also epichilium, mesochilium. |
|
homochlamydeous |
|
architecture |
flower |
Having a perianth undifferentiated into distinct proximal and distal envelopes (calyx and corolla); composed of tepals, all essentially alike. |
|
scarious |
|
texture |
|
Very thin, dry, and not green. |
|
intercostal |
|
position |
|
Between the costae. |
|
induplicate |
|
aestivation |
|
Basically valvate but with each member involute, the lateral abaxial surfaces of adjacent members contiguous. |
|
andromonoecious |
|
reproduction |
taxon |
Having all plants with both bisexual flowers and staminate ones. |
|
lacunate |
|
relief |
|
Having relatively large and deep depressions overall. |
|
soft |
|
texture |
|
Yielding under slight pressure. |
|
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
|
axis pl. axes |
|
STRUCTURE |
|
Any unitary and longitudinally continuous structure that bears laterally the subordinate portion(s), if any, of a plant root or shoot or any subdivision thereof and that represents the main line of structural development and/or symmetry distal to its origin, irrespective of the particular ontogenetic growth pattern involved. See also primary axis. |
|
aestivation |
|
CHARACTER |
|
Disposition of perianth (undifferentiated), calyx, or corolla members in the bud. |
|
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
|
brachiate |
|
architecture |
axis |
Having alternate, divaricate branches. |
|
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
|
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. |
|
diplotegium pl. diplotegia |
|
nominative |
fruit |
A pyxis with accessory tissue adnate to the pericarp; derived from an inferior ovary. |
|
syngenesious |
|
fusion |
flower, androecium |
Having the anthers connate or coherent and forming a ring. |
|
enation |
|
STRUCTURE |
|
A relatively small outgrowth from an otherwise regular boundary or surface of a larger structure. |
|
suprafoliar |
|
insertion |
|
Upon the stems, each directly above (distal to) and very near a point of leaf insertion. |
|
tomentose |
|
pubescence |
|
Bearing dense, short, stiff, capillate trichomes. See also tomentulose. |
|
exindusiate |
|
architecture |
sorus |
Lacking an indusium. |
|
epirhizal |
|
insertion |
|
Upon or arising from the roots. |
|
cilium 2 pl. cilia |
|
STRUCTURE |
|
A motile hair- or whip-like structure extending from the surface of a cell. |
|
epirhizal |
|
position |
|
Upon or arising from the roots. |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
