STRUCTURE |
|
The relatively short, simple, axial structure surmounting a pedicel and basal to the flower, usually broader than the pedicel. |
|
torus 2 pl. tori |
= receptacle |
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). |
