STRUCTURE |
|
A supporting axis or column that bears a structure at its apex; may be ontogenetically distinct from the structure that it bears, or may be the basal portion of an ontogenetic entity that includes both the stalk and the structure that it bears; usually narrower than the structure that it bears. |

Inversely turbinate (top-shaped). See also pyriform (pear-shaped). |
|
perianth |
|
STRUCTURE |
|
Collectively, all the sterile, primary, lateral organs (tepals, or sepals and/or petals) of a flower; inserted upon the floral axis immediately beneath (proximal to) the reproductive organs (androecium and/or gynoecium) and surrounding them, often protectively; lacking in some taxa; the individual members typically laminar and more or less foliaceous; widely regarded as consisting of the evolutionarily modified leaves of a fertile shoot; the constituent members undifferentiated with respect to one another, or else differentiated into more or less distinct floral envelopes (calyx and corolla), one or the other of which is deemed lacking in some taxa due to evolutionary reduction following differentiation. |
|
obtuse 1 |
= blunt |
apex |
|
Bluntly angular; having an angular tip whose generalized sides intersect at an angle of 90° or more. |
|
calceolate |
= slipper-shaped |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
|
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
|
clinandrium pl. clinandria |
|
FEATURE |
|
The cavity in a floral column (gynostemium) within which the anthers are borne. |
|
prop root |
|
STRUCTURE |
|
A relatively stout adventitious root arising from the lower portion of a main stem and extending outward and downward toward the substrate, within which it ultimately becomes anchored, thus buttressing the aboveground portion of the plant. |
|
rhizoid |
|
STRUCTURE |
|
Any structure that is similar to a root in appearance and function but that is not a true root ontogenetically and anatomically, especially one produced from a gametophyte thallus. |
|
divaricate |
|
arrangement |
|
Strongly divergent. |
|
sellaeform |
|
solid shape |
|
See selliform. |
|
subsidiary cell |
|
STRUCTURE |
|
One of the cytologically distinctive epidermal cells that are sometimes present in a stomate and that surround and are regularly oriented in relation to the guard cells. |
|
toothed |
= dentate |
margin |
|
Having regularly spaced, angular convexities oriented more or less perpendicular to the generalized perimeter. See also small-toothed (denticulate); See also sawtoothed (serrate), scalloped (crenate), small-sawtoothed (serrulate), small-scalloped (crenulate). |

STRUCTURE |
|
A trichome that is elongate, more or less straight, terete, fine-pointed, and stiff. |
|
partite |
? cleft, dissected, divided, lobate, lobed, parted, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protrusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
