|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
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. |
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
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. |
hypocotyl |
|
STRUCTURE |
|
That portion of an embryo axis between the level of cotyledon insertion above and the root meristem (or radicle, if present) below. |
corymb |
|
nominative |
inflorescence |
An indeterminate, more or less condensed raceme with the pedicels progressively shorter toward the distal end, the flowers all borne at approximately the same level, the whole generally plane or convex at the top, the flowers maturing from the edge inward (i.e., the proximal or outer flowers maturing first). |
internodal |
|
insertion |
|
Upon or otherwise directly associated with the internodes. |
sellaeform |
|
solid shape |
|
See selliform. |
dichlamydeous |
|
architecture |
flower |
Having a perianth differentiated into a distinct calyx (sepals) and corolla (petals). |
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
dehiscent |
|
dehiscence |
|
Splitting or forming one or more apertures at maturity, the contents thereby released for dispersal. |
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
leaf scar |
|
FEATURE |
|
A scar on a twig or stem due to abscission of a megaphyll; having an outline like that of a transverse section through the base of the petiole, sheath, or blade that was inserted there. |

|
odor |
|
Sickeningly sweet. |
disk |
|
STRUCTURE |
|
See disc. |
circinate 1 |
|
solid shape |
|
Terete and rolled downward from the apex in a tight coil. |
ephemeral |
|
duration |
plant |
Annual with a very short life span; germinating, growing, reproducing, and dying within a brief period of favorable conditions, the entire cycle being completed within a few weeks. |
conoidal |
|
solid shape |
|
Generally but not strictly conic. |
