Oenothera suffrutescens

Calylophus tubicula

(synonym of Oenothera tubicula)

linda tarde, scarlet beeblossom, scarlet evening-primrose, scarlet gaura, wild honeysuckle
Habit Herbs perennial, densely strigillose, sometimes also long-villous proximally, sometimes glabrate; from a deep, thick taproot, often with branching underground stems, or branching only at surface, these often becoming horizontal or nearly so and giving rise to new plants.
Stems

erect or ascending, usually many-branched, 10–120 cm.

Leaves

in a basal rosette (but not present at flowering) and cauline, 0.7–6.5 × 0.1–1.5 cm, blade linear to narrowly elliptic, margins entire or remotely and coarsely serrate.

Flowers

4-merous, zygomorphic, opening near sunset;

floral tube 4–11(–13) mm;

sepals 5–9(–10) mm;

petals white, fading salmon pink to scarlet-red, slightly unequal, obovate to elliptic-obovate or elliptic, 3–7(–8) mm, abruptly clawed;

filaments 3–6.5(–7) mm, anthers (2.5–)3–5(–5.5) mm;

style 10–22 mm, stigma exserted beyond anthers at anthesis.

Capsules

erect, pyramidal in distal 1/2 and abruptly constricted to terete proximal part, pyramidal part weakly or strongly angled, not conspicuously bulging at base, 4–9 × (1–)1.5–3 mm;

sessile.

Seeds

(1–)3 or 4, light to reddish brown, 1.5–3 × 1–1.5 mm.

Discussion

Oenothera suffrutescens is naturalized sporadically in southern California (Los Angeles, San Diego, Santa Barbara, and Ventura counties; although native in eastern part of the state), Illinois, Indiana, Michigan, New York, southern Ontario, and Wisconsin.

P. H. Raven and D. P. Gregory (1972[1973]) determined Oenothera suffrutescens to be self-incompatible and polyploid. It is known to form hybrids with O. calcicola and O. hispida.

Schizocarya kunthii Spach is an illegitimate name based on Gaura epilobioides that pertains here.

Subspecies 2 (1 in the flora).

H. F. Towner (1977) found that Oenothera tubicula is self-incompatible and diurnal with opening times just prior to sunrise. It occurs primarily on limestone soil in arid lowlands, but occasionally in montane areas, from Guadalupe County, New Mexico, south to western Texas, northeast to Howard County, Texas, and south to northern Zacatecas, south-central Nuevo León, and southwestern Tamaulipas, 600–1800 m. Subspecies strigulosa (Towner) W. L. Wagner & Hoch is known only from rocky, open sites and canyons in relatively montane areas, sometimes in pine forests in southernmost Coahuila, south-central Nuevo León, and southeastern Tamaulipas, from 1500 to 2300 m. It differs in being strigillose on the ovary and distally on stems, leaves linear to narrowly lanceolate, and the petals fading red or purple.
