Key characteristics

North of Paposo, at Aguada del Panul, this species grows together with O. johnstonii, with which it can be confused. O. triangularis has slightly larger leaves, 3–5 × 5–15 mm, (vs. c. 1–3 × 3–5 mm) which are grouped in alternating bundles. The leaves, which have short stalks, are triangular with a wedge-shaped base and an acute apex, the margins are regularly lobed and rolled. The inflorescence is spike-like, and the flowers are stalked and in O. johnstonii the inflorescence is less dense and the flowers are stalkless (Merklinger & Luebert, 2020).
