Perennial herbs, up to 1.5 m high. Leaves with a petiole 1–3 cm long, ovate blade, 3–8 × 2–4 cm, truncate or cordate base, acute apex, irregularly serrate margin, abaxial surface hispid, adaxial surface scabrous. Flowers sessile or with a short pedicel, up to 2 mm long, arranged in 4–8 flowered verticillasters, axillary to inconspicuous bracts, forming dense pseudo-spikes. Calyx 2.5–4 mm long, with 5 triangular teeth. Corolla white or violet color, 3 mm long, superior lip 1 mm, bilobate, inferior lip 1–2 mm long, trilobate. Style 2.5–3.5 mm long. Nutlets ellipsoid 1.5 mm, chestnut color.

Remarks:— C. fastigiata is very similar to Condea undulata (Schrank) Harley & Pastore (2012: 14) , however this last species does not occur in Argentina. In Brazil these two species have slightly different but overlapping distribution: Condea undulata is more coastal and with a more northern distribution, C. fastigiata occurs often more inland and has a slightly more southern and western distribution (R.M. Harley, pers. comm.). Both taxa are here considered two separate though closely related species, as Bentham (1833) originally proposed. For further details of diagnostic characters, see Harley (1985).

Distribution and habitat: — Condea fastigiata grows in Brazil, Paraguay, Uruguay and northern Argentina.
