STRUCTURE |
|
A diminutive squama (lepis). |
|
hippocrepiform |
= horseshoe-shaped |
solid shape |
|
Relatively slender and strongly compressed, the whole strongly curved over its length in a plane perpendicular to the direction of compression and forming an incomplete circle, the ends somewhat straighter than the rest and parallel or nearly so; like a horseshoe. |

keel 2 |

megaspore |
= macrospore (not recommended) |
STRUCTURE |
|
A female spore; a spore of the larger of two types produced by the sporophytes of a heterosporous taxon; produced in a megasporangium; giving rise upon germination to a megagametophyte. |
|
cleft |
? dissected, divided, lobate, lobed, parted, partite, segmented |
solid shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the margin or surface 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 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. 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). |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |

> apical |
insertion |
|
Upon or associated with the portion of a structure farthest from its developmental origin. |
|
revolute 1 |
|
margin |
|
Rolled inward abaxially. |
|
segmented |
? cleft, dissected, divided, lobed, lobate, parted, partite |
plane shape |
|
Having two or more major 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 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.

See also cut (incised, lacerate, torn), laciniate (slashed). |
|
fringe |
= fimbria |
STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible segments or protrusions, when treated as an aggregate structure. |
|
spiny 1 |

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. |

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). |
