In some flowers, the sepals are fused towards the base, forming a "'calyx tube "'( as in the Lythraceae family, and Fabaceae ).
12.
"' Flowers "'are numerous Calyx tubes are approximately 5 mm long, abaxially yellow pubescent, densely so on ovary and tubular part, more sparsely so on cup-shaped part.
13.
There are 15 20 stamens, inserted on the calyx tube; filaments thread-like; anthers purplish, introrse, two-celled; cells opening longitudinally; the pistil has a superior ovary in the bottom of calyx tube, one-celled, with two ovules.

The two can be distinguished by the smaller flowers of " A . paupercula " ( " A . purpurea " has a corolla of ), and by the long lobes of the calyx, which in " A . purpurea " are typically not more than half the length of the calyx tube.
16.
Flowers are bisexual, white, in axillary spreading panicles; pedicels 5-ribbed; ribs alternating with sepals; calyx tube very short, adnate to the base of the ovary; lobes 5, ovoid-deltoid, acute, pubescent; petals 5, white, oblong; stamens 15 in 2 rows; filaments short, flattened at base; anthers oblong, shortly apiculate; ovary superior, covered with large shallow pits, lepidote, 3-celled, ovules 2 in each cell; style about as long as ovary, ribbed; stigmas densely papillose, obscurely 3-lobed.

Other characters are generally found in Huerteales, but with the exceptions noted below . " Gerrardina " differs from the rest of Huerteales in that the stamens are opposite the petals, instead of being opposite the sepals . " Dipentodon " and " Perrottetia " are distinctive in that the calyx and corolla are not well differentiated, but resemble each other . " Tapiscia " and " Huertea " have a calyx tube and uniloculate ovary with a single ovule . " Huertea " has one locule containing two ovules, or two locules, each containing one ovule . " Gerrardina ", " Dipentodon ", and " Perrottetia " have two ovules in each locule . " Tapiscia " lacks the nectary disk that is characteristic of the order . " Huertea " lacks stipules.
