ray floret |
|
STRUCTURE |
|
A floret that has a zygomorphic corolla, is pistillate (either fertile or sterile) or neuter, and is borne in a radiate capitulum (head) peripheral (proximal) to the disc florets; in Asteraceae (Compositae). |

STRUCTURE |
|
The relatively short, simple, axial structure surmounting a pedicel and basal to the flower, usually broader than the pedicel. |
|
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). |
|
receptacular |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
receptacular |
|
position |
|
Upon, arising from, or otherwise directly associated with the receptacle. |
|
receptacular bract |
= pale, palea, palet |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle (torus) of a capitulum (head) in Asteraceae (Compositae). |
|

|
vernation |
|
Each with its blade oriented downward and parallel to the proximal portion of its distally recurved petiole. |
|
reclining |
|
habit |
axis |
Inserted above substrate level and recurved, the distal portion procumbent. |
|
rectangular |
|
plane shape |
|
Basically four-sided, the sides more or less straight, those of each opposing pair more or less parallel, the generalized angles between adjacent sides approximately 90°. |
|
recurved |
= arching |
orientation |
|
Curving outward (abaxially), downward, or backward. |

|
CHARACTER |
|
Aspect as to proportion and pattern of incident light reflected from the surface. |

orientation |
|
Abruptly bent outward (abaxially), downward, or backward at some point along its length. |
|
regular |
= actinomorphic |
architecture |
perianth, calyx, corolla |
Radially symmetric; divisible into two essentially equal portions along any median longitudinal plane. See also peloric. |

= sculpture |
CHARACTER |
|
General topographic aspect of a surface. Overlaps conceptually with solid shape. |
|

= distant |
arrangement |
|
Disposed relatively far from one another along the axis. |
|
reniform 1 |
= kidney-shaped |
plane shape |
|

|
reniform 2 |
= kidney-shaped |
solid shape |
|
Thickly elongate and arcuate, circular or compressed-circular in transverse section, each end bluntly rounded; like the generalized shape of a human kidney. |
