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."[2]
"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."[2]
Distribution
O. filipes ranges from South Carolina west to Tennessee and southern Indiana, south to northeast Florida and eastern Louisiana.[1]
Ecology
Habitat
O. filipes occurs in dry or well drained sandy soils and sandy loam.[3] It seems to be most common in areas that receive full sun or are only partially shaded.[3] It can be found in longleaf pine flatwoods or sandhills, scrub oak barrens, pine-oak woodlands, and limestone glades.[3] However, it can also appear in areas of disturbed habitat, including roadsides and common use recreational areas.[3] O. filipes responds negatively to soil disturbance by agriculture in Southwest Georgia.[4]
Associated species include Pinus palutris, Solidago, Gaillardia, Polianthes, Berchemia, Dichromema, Setaria, Hedyotis, Schoenus nigricans, Muhlenbergia carpillaris, and Quercus laevis.[3]
Phenology
This species flowers from April through July.[1]
Seed dispersal
This species disperses by gravity.[5]
Fire ecology
This species has been found in habitat that is often maintained by fire.[3]
