Description

Oenothera filipes is a perennial herbaceous species.

"Usually coarse, branched annuals or perennials. Leaves mostly alternate. Inflorescence terminal, spike-like, with or without axillary branches from upper leaves or bracts. Petals white to pink; stigmas 3-4 lobed. Fruit woody, indehiscent." [1]

"Plant to 1.5 m tall, stems pubescent. Leaves linear, elliptic or narrowly lanceolate, to 6 cm long and 6 mm wide, pubescent, glabrous, or puberulent, acute, coarsely toothed to undulate, attenuate; sessile or subsessile. Inflorescence diffusely branched, the branches uncinulate. Spelas and petals 4-7 mm long; anthers 1.6-2.5 mm long styles exerted 5-7 mm. fruits acutely 4-angled, ovoid, 3.5-4 mm long, 3-3.5 mm broad, minutely uncinulate to almost glabrous; pedicels 2-3 mm long, uncinulate."[1]

Distribution

Ecology

Habitat

O. filipes occurs in dry or well drained sandy soils and sandy loam. [2] It seems to be most common in areas that receive full sun or are only partly shaded. [2] It can be found in longleaf pine flatwoods or sandhills, scrub oak barrens, pine-oak woodlands, and limestone glades. [2] However, it can also appear in areas of disturbed habitat, including roadsides and common use recreational areas. [2] Associated species include Pinus palutris, Solidago, Gaillardia, Polianthes, Berchemia, Dichromema, Setaria, Hedyotis, Schoenus nigricans, Muhlenbergia carpillaris, and Quercus laevis. [2]

Phenology

This species has been observed to flower and fruit from August to October. [2]

Seed dispersal

This species disperses by gravity. [3]

Fire ecology

This species has been found in habitat that is often maintained by fire. [2]
