The flowers are yellow to green--yellow, actinodromous, with six subequal tepals, nine bilocular anthers and unicarpelar, unilocular, minutely pubescent ovary, sunk into the floral tube in a hypanthium that develops with fruit ripening forming a turbinated cupule, often 4-to 5-parted, red-colored, with floral remains in the margin.
Flores 3-9 per inflorescentiam, pediceli 1-4 mm longi; calycis lobuli deltati, hypanthium infundibuliforme.
7 cm, white, and by numerous slender stamens; the inferior ovary is ellipsoid and surrounded by a hypanthium densely covered with scales, long, filiform hairs, and short spines.
It is unclear if the petals were completely free, born on the rim of a hypanthium (implying adnation of calyx and corolla), or if they were fused at the bases and free at the tips, where the separation would occur at a level obscured by the calyx.
The fruit is pomaceous, type cactidio, with succulent hypanthium, pericarp and seeds immersed in a gelatinous mass (ROSA; SOUZA, 2003); its color varies between yellow and red.
For this purpose, a hole was made in the base of the hypanthium using a 100[micro]l capillary tube; immediately thereafter, as many as 20[micro]l capillary tubes as necessary to extract all the nectar found in the nectar chamber were introduced, measuring the length of the nectar column in the capillary tubes to determine the volume.
Some of the major differences in the formulae are related to the fact that species in the Onagraceae have a floral tube or hypanthium, and this structure is represented in quite different ways in the three formulae.
As in the remaining members of the Sicyeae, Cyclanthera shows a central androecial column, nectaries derived from secretory trichomes on the hypanthium (see Vogel, 1981), and 4-6-zonocolporate pollen (cf.
On every second day during the rest of the flowering season (6-16 August 1994), I removed the anthers from a single flower on each marked branch before dehiscence and marked the base of the hypanthium with a spot of paint.
Flower color, hypanthium color, and hypanthium length were measured.
