Ecology: Montane forest; on leaf litter, humus and soil. Elevation: 2740 m. Distribution: Endemic to the tropical Andes (Ecuador).
Breutelia aciphylla is by far the largest species in the tropical Andes. The species is characterized by leaves to 12 mm long, 2 mm wide near base, narrowly lanceolate from a short ovate, rusty red base, gradually long acuminate, margins subentire (weakly dentate), laminal cells porose, basal margin cells enlarged, in ca. 4 (3-5) rows, extending to about the mid length of the expanded ovate leaf base. The collection reported from Colombia (Cauca: Churchill & Betancur 18136; FLAS, HUA, MO, NY) is not B. aciphylla.
Specimens: ECUADOR. Pichincha: Toapanta & Churchill 1159 (MO, QCNE).
