STRUCTURE |
|
A more or less dry, hard or fibrous, simple or compound enclosure or outer layer of a seed, fruit or inflorescence. |
strigose |

A small, generally round sector of distinct coloration or relief. |
bursicle |

STRUCTURE |
|
A pouch- or flap-like protrusion from the stigma that encloses the caudicle of a pollinium. |
mitre-shaped |
= mitriform |
solid shape |
|
Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. |
vermiculate |
= worm-shaped |
solid shape |
|
Basically cylindric, elongate, and slender with bluntly rounded ends, variously curved over its length. |
spheric(al) |
= globose, globular, orbicular, rotund, spheroid(al) |
solid shape |
|
Uniformly convex, circular in any median section and in outline when viewed from any angle; like a sphere or globe. |
cuculliform |
= cucullate, hood-shaped |
solid shape |
|
Convex or compressed-convex overall with a distal peak or ridge, relatively thin-walled and essentially hollow with the interior open to one side below the distal portion; resembling a hood or cowl. See also galeiform (galeate, helmet-shaped), which overlaps conceptually. |
anther |
|
STRUCTURE |
|
The fertile, loculate, pollen-bearing portion of a stamen, containing one, two, or four thecae (pollen sacs), when that portion is differentiated from and borne at the summit of a narrower supporting stalk (filament), or when such differentiation is deemed to have occurred in the evolutionary past with subsequent reduction of the filament (the anther then sessile and constituting the entirety of the stamen). |
plaited 2 |
= pleated, plicate |
vernation |
|
Having alternately adaxial and abaxial lengthwise folds, resembling a closed fan. |
irregular 2 |
|
course |
|
Deviating asymmetrically from a straight line. |
equitant |
|
arrangement |
|
Alternate, distichous, basal, and congested, each conduplicate with its lateral edges overlapping and/or overlapped by those of the immediately adjacent one(s). |
root 1 |
|
STRUCTURE |
|
Collectively, all those portions of a plant body that are anatomically distinct from the shoot, the component axes not differentiated into nodes and internodes, and branching endogenously. |
chaffy 1 |
= paleaceous |
pubescence |
|
Of or bearing small, thin, more or less erect, papery (chartaceous) to membranous, planate trichomes. |
oblate |
|
plane shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
oblate |
|
solid shape |
|
Symmetrically elongate and broader than long perpendicular to the developmental or polar axis. |
discal |
|
insertion |
|
Upon or otherwise directly associated with the floral disc. |
axillary |
|
insertion |
|
Within the axil; nodal and at or very close to the vertex of the distal angle between a lateral structure, especially a leaf, and the axis that bears it. |
pubescence |
|
CHARACTER |
|
Collective aspect of trichomes borne on the surface. Many of the terms traditionally used for describing pubescence have been defined and used in so many differing and often contradictory ways that they have become hopelessly ambiguous. This is attributable mainly to overdefinition within this portion of the traditional lexicon — that is, to highly arbitrary and widely variant restriction of a term's scope to some one detailed combination of trichome character states (shape, size, orientation, etc.). By derivation these are essentially general terms, really suited only for denoting overall aspect. The diversity actually encountered in nature defies comprehensive and unambiguous resolution into any limited suite of precisely specified, mutually exclusive, complex character states that can be associated with these terms, which are best used only in their general senses. Sometimes, such description will be sufficient in itself; more often, additionally or alternatively, the various attributes of the individual trichomes should be described. This is the only strategy that allows for full description of any possible condition, including the presence of more than one type of trichome. The various terms used for describing pubescence have never been semantically consistent; in some cases they refer to the trichomes themselves, while in others they apply to the bearing surface or structure; e.g., sericeous (the trichomes themselves are collectively silky) versus barbate (the structure is bearded). See also coating, indumentum (vesture). |
branch |
|
STRUCTURE |
|
Any higher-order division of or outgrowth from an axis, vein or veinlet when such division or outgrowth is equivalent in nature to the structure of origin. |
tri… 2 |
= thrice-…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in tripinnate. See also entries for particular terms beginning with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
median |
= central, medial |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
flange |
|
STRUCTURE |
|
A relatively broad, circumferential rim or ridge that protrudes laterally. |
reticulate 3 |
= netted |
relief |
|
Having prominulous, more or less regularly interconnected lines. |
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
