Description (diagnostics are in brown)

Fruit a dry schizocarp, oblong-ovoid, terete to slightly compressed laterally, (1.75)2–3(4) mm long (including stylopodium) x 0.75–1.5 mm wide, gray, consisting of two one-seeded, indehiscent segments (mericarps) that separate at maturity.

Mericarps polymorphic, oblong-ovate, rounded on adaxial side, convex on abaxial side. Abaxial side with five obscure primary ridges, covered with appressed, white antrorse hairs, variously ornamented between the ridges: covered with straight, stiff, granulate to minutely retrorsely barbed pericarp spines of varying lengths (up to 2 mm) and thickness, tipped with a rosette of minute retrorse barbs; or covered with numerous short, thick, granulate tubercles of uniform size; or covered with granulate tubercles from the base, graduating in length to nearly spine-like at the apex. Oil ducts obscure in cross-sectional view of mericarp (two evident along deep longitudinal groove on adaxial side.)

Endosperm rolled inward along groove.
