Strobilopsis

Annual or perennial herbs; stems leafy throughout, narrowly ridged by decurrent leaf bases, pubescent, hairs retrorse and minutely glandular. Leaves opposite below, alternate above, narrowly elliptic to linear-oblong, entire or toothed, thick, glandular-punctate. Flowers in terminal, capitate inflorescences, solitary or with few to several smaller heads on short, leafy, axillary shoots below main one, globose or oblong-cylindrical, erect, scarcely elongating in fruit. Bracts roughly as long as broad, concave, clearly distinct from leaves, adnate to minute pedicel, free from calyx. Calyx unequally 5-lobed, thin-textured. Corolla tubular, bilabiate, 5-lobed, longer than calyx; tube funnel-shaped, glabrous or very minutely glandular outside; posterior lip 2-lobed, exterior in bud, base with orange patch and clavate hairs; anterior lip 3-lobed; lobes spreading, oblong-elliptic, entire. Stamens either 4 and didynamous, or 2 or 3 by reduction of anterior pair, arising near top of corolla tube, exserted; posterior filaments decurrent to base of tube; anthers synthecate, dorsifixed; staminodes 0. Nectary at base of ovary on posterior side. Ovary bilocular, +/- oblong-elliptic; ovules up to 6 per locule on upper part of placenta, few developing; style minutely glandular-puberulous; stigma lingulate, flattened, with 2 marginal bands of stigmatic papillae, nearly as long as style, exserted. Fruit a septicidal capsule with a short loculicidal split at tip of each valve, minutely glandular on sutures. Seeds 1-4 per locule, each seated on a massive, pulvinate funicle, elliptical, convex on outer face, flat on inner, sinuously wrinkled, pallid, eventually blackish brown.
