legume |
|
nominative |
fruit |
Dry, septicidal, one-loculed and derived from a single, superior, simple ovary; dehiscing along two sutures, one abaxial, one adaxial; in Fabaceae (Leguminosae). See also loment. |
cupule |
|
STRUCTURE |
|
A cup-like structure inserted at the base of a fruit, partially enclosing it or not; composed of a persistent, usually dried, sometimes hardened involucre, perianth, or portion thereof, the constituent parts often coalescent, yielding a unitary structure. |
marcescent |
|
duration |
structure |
Persistent in a distinctly withered condition. |
monopodial |
|
architecture |
axes |
Branching laterally, each axis of each order of branches produced by a single, persistently dominant, apical meristem. See also sympodial. |
suture |
|
FEATURE |
|
An evident line of ontogenetic union. |
dehiscence |
|
CHARACTER |
|
Mode of opening (splitting or forming apertures). |

architecture |
flower, androecium |
Diadelphous with four stamens in one set and two in the other. See also didynamous. |
taprooted |
|
architecture |
plant |
Having a taproot. See also diffuse-rooted, fibrous-rooted. |
elater 1 |
|
STRUCTURE |
|
An elongate cell with a helical, hygroscopic thickening in its wall, contained within a sporangium, expanding and contracting with changes in humidity and aiding dispersal of the spores; esp. in Hepaticae. |
extrorse |
|
dehiscence |
anther |
Opening outwardly, on the abaxial side. See also introrse, latrorse. |
erect |
|
orientation |
|
Perpendicular to the horizon or to the general plane of a bearing structure. |

|
texture |
|
Limp, sometimes appearing withered or shrunken. See also tumid (swollen, turgid). |
perulate |
|
architecture |
bud |
Having outer scales that enclose and protect the embryonic components, from which they differ significantly in texture, shape, size, relief and/or vestiture. See also naked. |
bursicle |
|
STRUCTURE |
|
A pouch- or flap-like protrusion from the stigma that encloses the caudicle of a pollinium. |
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |

architecture |
pollen grain |
Having the number of pores indicated by the prefix; as in monoporate, polyporate, triporate. |
vascular bundle |
|
STRUCTURE |
|
A discrete strand of conducting tissues (xylem, phloem) and associated cells (e.g., cambium) within a stem or other axial structure. |
