Stamens inserted towards the base of tube. Mericarps ovoid, 6-8 mm long; outer face convex, densely prickly"  (NSW PlantNET).

Habitat/ecology:  "In Chile this species grows in the following environmental conditions:  Medium altitude up to the timber line; low altitude, interior valleys; coastal mountains, 500-2000 m; coastal areas, 0-500 m.  Humid areas, with almost constant rainfall, short dry periods are possible (generally not longer than 1 month); somewhat dry areas where the drought may last 3-5 months, precipitations of 400 - 800 mm. are concentrated in winter.  Some shadow, some protection against direct sunlight, some shadow from vegetation, filtering about 20-40% of light; in shadow, steep slopes facing south or a vegetation cover which filters 40-80% of light"  (Chileflora).
