Plants 10–60(–120) cm. Stems (erect to decumbent) usually branched. Leaves evenly distributed along stems; petiolate; blades oblanceolate or obovate to spatulate, often lyrate, sometimes ± pinnatifid (terminal lobes usually shorter than pinnatifid portions, crenate to irregularly incised), membranous to slightly chartaceous, ultimate margins crenate or entire, faces ± velvety. Heads in corymbiform arrays. Peduncles hairy (some hairs reddish, bulbous-based, wartlike, surpassing white, appressed hairs). Involucres 13–17 mm diam. Ray corollas deep yellow to orange-yellow, abaxial veins (sometimes whole surfaces) red to maroon, laminae 10–14 × 5.5–8 mm. Disc corollas red to maroon (rarely yellow). Cypselae 4.5–6 × 2.7–3.7 mm. 2n = 30.


Phenology: Flowering nearly year round.

Discussion

Berlandiera lyrata is cultivated in Arizona. Exceptional specimens that are scapiform (sometimes monocephalic) with mostly undivided leaves and with wartlike hairs on peduncles occur at higher elevations (south-central New Mexico, trans-Pecos Texas, and Nuevo León). They have yellow disc corollas, as do most collections from Chihuahua, Durango, Nuevo León, and Tamaulipas.
