The taxonomic history behind the Asemeia genus which previously was under the Polygala genus and is still under the Polgalaceae family. Asemeia grandiflora was previously Polygala grandiflora but since has changed in 2012. More information can be found in their paper, Taxonomic notes and new combinations for Asemeia (Polygalaceae).

Description

This description of Asemeia grandiflora comes from Radford (1964) which recognized A. grandiflora as a synonym of Polygala grandiflora. A. grandiflora is a perennial herb with appressed or spreading pubescent stems that grow to approximately 2.5-5 dm tall. The leaves are alternate and oblanceolate to linear-oblanceolate, and are rarely elliptic. The leaves are 1.5-5 cm long, and 2-17 mm wide, and are somewhat pubescent underneath, especially on the veins. The racemes are 0.5-1.7 dm long. The sepals are green in color, are 1.5-2 mm long. The wings are pink in color with green veins and orbicular to reniform, and 5-7 mm long with tapered to claws. The corolla is shorter than the wings and is not lacerate the apex. There are 8 stamens. The seeds are black in color, are densely pubescent, and are approximately ca. 2 mm long. The aril is 3-lobed where the lobes do not extend up and around the seed body. Flowers from May to July.[2]

Distribution

Ecology

Habitat

This species has been found growing within calcareous glades, upland pine woods, longleaf pine-scrub oak sand ridges, savannas, and sandhill communities.[3][4] It has also been observed growing in swales of slash pine plantations.

Phenology

This species has been observed flowering and fruiting in May.[4]

Seed dispersal

This species disperses by explosion mechanisms or by ants. [5]

Fire ecology

Flowers within two months of burning in early summer.[6]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Asemeia grandiflora at Archbold Biological Station:[7]

Megachilidae: Anthidiellum notatum rufomaculatum

Use by animals

Deyrup observed this bee, Anthidiellum notatum rufimaculatum, on A. grandiflora.[3]
