Matará, entre Tingo y San Miguel de Asunción, Chileto, [7°16'S, 78°16'W], 1600–1700 m, 10 April 1950, R. Ferreyra 7070 (K, MO, US). Note. The following specimens from dry forest dominated by Eriotheca Schott & Endl. at 2137–2281 m in Ancash and Huánuco differ in the smaller corolla c. 1.5 cm long, shorter capsule (4–5 mm long) and slightly smaller calyx. However they share the same terminal inflorescence with axillary flowers, the same gaping corolla and 2 - seeded capsule. The leaves are similar in shape but are very variable in size. They may simply be a variant of the poorly known Justicia reginaldii. Additional material examined. Peru • Ancash: Prov. Sihuas, Dist.
