Shrubs, 50-130 cm. Leaves mostly opposite, sometimes alternate (distal); petioles 2-8 mm; blades deltate to deltate-ovate, 1-3.5 × 1-3.5 cm, margins usually toothed, faces: abaxial hispid and gland-dotted (and slightly reticulate), adaxial scabrous, (bases of hairs notably enlarged). Heads (1-)3-5. Peduncles 1-15 cm. Involucres hemispheric, 8-13 × 5-9 mm. Paleae ovate to oblong, 5.5-7 mm. Phyllaries 16-28, 3-9 × 1.5-2 mm. Ray florets 8-15; laminae 10-15 mm. Disc florets 50+; corollas 3.5-5 mm. Cypselae 2.7-3.2 mm; pappi of 2(-6) lacerate, aristate scales 2.1-2.5 mm plus (0-)2-6 lacerate scales 0.5-1 mm. 2n = 36.
Flowering (Jan-Oct). Xeric scrub; 500-1500 m; Ariz., Calif., Nev.; Mexico (Baja California, Sonora).
Bahiopsis parishii is a diploid that is closely related to polyploids that have traditionally been recognized as varieties of B. (Viguiera) deltoidea and occur throughout the Baja California Peninsula in Mexico.
Common Name: Parish goldeneye
Duration: Perennial
Nativity: Native
Lifeform: Subshrub
General: Perennial shrub, straggly 50-130 cm tall, with slender, strigillose to hispid stems and peduncles.
Leaves: Mostly opposite, on petioles 2-8 mm, blades deltate to deltate ovate 1-3.5 cm long by 1-3.5 cm wide, margins usually toothed, faces hispid and gland dotted beneath, scabrous above.
Flowers: Heads several at end of branching, naked, terminal, peduncle 1-15 cm long; campanulate involucres, 8-13 mm wide, 16-28 phyllaries lance-linear, 3-9 mm long by 1.5-2 mm wide; 8-15 ray florets with yellow rays 10-15 mm long; disc florets 50, yellow, corollas 3.5-5 mm.
Fruits: Cypselae 2.5-3.5 mm, compressed, oblong, distinctly ridged, strigose with brownish, forwardly appressed hairs.
Ecology: Found on plains, along arroyos, and slopes, always in xeric conditions below 5,000 ft (1524 m); flowers November-April.
Distribution: AZ, CA, NV; south to MEX (Baja California, Sonora).
Notes: This is a recently segregated species, you-ll know it by its old name: Viguiera deltoidea var. parishii. The molecular systematics are pretty clear to delineate the new genus Bahiopsis.
Ethnobotany: Unknown
Etymology: Bahiopsis is named for Juan Francisco de Bahi y Fonseca (1775-1841) a Spanish botanist, and opsis which indicates a resemblance, while parishii is named for the brothers Parish, Samuel Bonsall Parish (1838-1928) and William Fletcher Parish (1840-1918), botanical collectors who lived in California.
