central part of the inflorescence, straight, curved, or circinate during development
at the shoot apex, rarely with adhesive terminal disks. Inflorescences axillary,
bracteate or rarely ebracteate, cymose, the central pedicel developed into a
tendril, the peduncle very reduced or usually absent, the pedicels then arising
collateral to the tendril (sometimes aborted), solitary or paired; secondary
inflorescences may be present as condensed axillary or terminal shoots,
determinate or rarely indeterminate; pedicels articulate distal to bracts, the distal
portion called the floral stipe; bracts setaceous and scattered to foliaceous or
pinnatifid and involucrate, occasionally glandular at margin. Flowers bisexual
(sometimes functionally staminate), actinomorphic or rarely the reproductive
parts zygomorphic; hypanthium ± flat to campanulate, occasionally the perianth
basally connate/adnate into a floral tube; sepals 5 (very rarely 8), quincuncially
imbricated (rarely non-overlapping) in the bud, occasionally carinate, sometimes
with a subapical projection; petals 5 (very rarely 8) or sometimes wanting,
quincuncially imbricated (rarely non-overlapping) in the bud, the same length as
or shorter (rarely longer) than the sepals; corona present at the base of the calyx
or corolla or adnate to the inside of the floral tube, in 1 to many series of distinct
to occasionally connate, short to elongate, often showy filaments or outgrowths,
sometimes membranous, the innermost series, called the operculum, often
connate at least basally, frequently membranous and shielding the nectary; the
limen (extrastaminal nectariferous disk) present as a ring or cup around base of
androgynophore (or rarely the ovary if androgynophore absent), or discoid or
conical and adnate to the floor of hypanthium. Stamens 5(8 in one species),
