Orobanche parishii subsp. parishii

Treatment appears in FNA Volume 17. Treatment on page 483.

Plants (10–) 15–22 (–35) cm. Inflorescences 5–8 cm. Calyces radially symmetric, (7–) 10–15 (–18) mm, lobes subulate-attenuate, (6–) 9–13 mm, apex often recurved or twisted. Corolla lobes internally usually with maroon or reddish purple stripes or veins distally, 18–25 mm, lips 6–8 mm; anthers moderately woolly on sutures; stigma unequally 2-lobed or not, lobes spreading, not recurved, thin. 2n = 48.


Phenology: Flowering Mar–Sep.
Habitat: Open chaparral, scrub, pinyon-juniper woodlands, rocky soils.
Elevation: 200–2700 m.

Distribution

Calif., Nev., Oreg., Mexico (Baja California)

Discussion

Confirmed frequently reported hosts are Artemisia dracunculus, Baccharis sergilioides, Corethrogyne filaginifolia, and Hazardia squarrosus (Asteraceae). Infrequently reported hosts are A. nova, A. tridentata, Ericameria nauseosa, Eriophyllum confertiflorum, E. lanatum, and Iva axillaris (Asteraceae).

The diversity of reported hosts and range of elevation, habitat, and morphology reported for subsp. parishii suggests that it encompasses multiple lineages or that it comprises one or more hybrids with unstable host preferences. Some specimens cited by L. R. Heckard (1973) were previously misidentified as Orobanche ludoviciana.
