STRUCTURE |
|
A relatively thin layer of tissue that covers or separates other, different tissue(s) and/or empty space(s). |

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. |
|
prominulous |
< raised |
prominence |
|
Diminutively prominent, protruding only slightly above the general level of the surrounding surface. |
|
spire-shaped |
= strombuliform |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
|
tooth pl. teeth |
= dens |
STRUCTURE |
|
One of a series of regularly spaced, angular, marginal convexities oriented more or less perpendicular to the generalized perimeter of a laminar structure. See also sawtooth, sawtoothlet, scallop (crena), scalloplet (crenule), toothlet. |
|
intravaginal |
|
insertion |
|
Within the leaf sheath. |
|
vasculature |
|
STRUCTURE |
|
The vascular strands of all orders (veins and veinlets) in a particular part or organ, regarded collectively; consisting of conducting tissues (xylem, phloem) and associated supporting and enclosing tissues (e.g., sclerenchyma, collenchyma). |
|
lineate 2 |
> streaked, striate |
relief |
|
Having very narrow, straight, shallow depressions or low protrusions. See also lineolate. |
|

|
bristle 2 |
= seta; > glochid, glochidium; < trichome |
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). |
|
epirhizal |
|
position |
|
Upon or arising from the roots. |

flush |
|
prominence |
|
Even with the surrounding surface, neither higher nor lower than its general level. |
|
strigillose |
= strigulose |
pubescence |
|
Finely strigose. |
|
tessellate 2 |
= checkered |
relief |
|
Having a pattern of regularly disposed squares marked by raised or depressed vasculature. |
|
uni… |
= mono…, one-…, single-… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in unicellular, unifloral, unifoliate. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
|
lens-shaped 1 |
= biconvex, lenticular |
plane shape |
|
Elongate, narrow, broadest at the middle, attenuate to acute ends, the sides convex; like the outline of a couble-convex lens viewed from its edge. |
