architecture |
|
Bearing spines. |
|
heart-shaped 3 |
= cordiform |
solid shape |
|
Having two rounded basal lobes, broadest near the base and fairly regularly attenuate to an essentially angular apex; like the stylized form of a heart. See also obcordiform. |
|
subpetiolar |
|
position |
|
Just below the point of petiole insertion. |
|
internode |
|
STRUCTURE |
|
Any portion of a stem between two successive nodes. |
|
tiller |
|
STRUCTURE |
|
An erect or ascending stem that branches from the base of another at or below the surface of the ground; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
|
limb 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret distal to the level of filament insertion; in Asteraceae (Compositae). |
|
adaxial |
= ventral (not recommended) |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
arista pl. aristae |
= awn, bristle, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
|
maculate |
= blotched, spotted |
coloration |
|
Having one or more areas that differ in color from the rest of the surface. See also eyespotted. |
|
non-stomate-bearing |
= astomatiferous |
architecture |
|
Lacking stomates in the epidermis. |
|
parted |
? cleft, dissected, divided, lobate, lobed, partite, 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). |
|
coronal |
|
position |
|
Upon or otherwise directly associated with the corona. |
|
receptacle 2 |
= torus |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
epiphyllous |
|
insertion |
|
Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
|
scape |
|
STRUCTURE |
|
A leafless, essentially naked, inflorescence-bearing stem (or peduncle) arising directly from a caudex or rhizome, its point of insertion slightly beneath, at, or slightly above the substrate surface. |
|
floricane |
|
STRUCTURE |
|
A biennial or perennial stem after it has begun flowering, when that does not occur until at least its second season of growth; applied especially to the stems of brambles (Rubus spp.). |
|
spadix pl. spadices |
|
STRUCTURE |
|
A thick, fleshy, primary inflorescence axis bearing sessile flowers more or less sunken into its surface, the whole subtended and sometimes partially enclosed by a specialized bract, the spathe; esp. in Araceae. |
|
streaked 1 |
= striate |
coloration |
|
Having an overall pattern of fine, more or less parallel lines of contrasting hue and/or intensity. |
|
indumentum pl. indumenta var. indument |
= vesture |
STRUCTURE / SUBSTANCE |
|
The trichomes and/or exuded substance that overlie a surface proper, regarded collectively. See also coating, pubescence. |
|

= coriaceous |
texture |
|
Moderately thick, tough, and very pliable. |
|
absent |
|
presence |
|
Not occurring within the context in point. |
|

|
STRUCTURE |
|
The apex of a connective, when prolonged above the union of the anthers. |
|
lobate |
? cleft, dissected, divided, lobed, parted, partite, segmented |
solid shape |
|
Having one or more component sectors or peripheral protrusions that is/are delimited by concavities in the surface or margin and that is/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 protusions 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.
