general taxon notes:

      Ecology. Humid and semi-humid puna; on soil. Elevation. 3700-4800 m. Distribution. Bolivia: Cochabamba, La Paz, Potosí. World range: Mexico, Colombia to Bolivia.

      The recurved leaf margins of this species is unique among the Andean taxa of Hennediella. Barbula weddelii Schimp. Ex Müll. Hal. and Tortula leiostoma Herzog are synonyms; the former is based on a collection made by Weddell in 1851 from Chuquiaguillo (Department of La Paz), the latter based on a collection by Herzog made in 1911 from Llavetal. A further synonym is Hennediella limbata (Mitt.) R.H. Zander.

      Specimens. Cochabamba: Herzog 3178 (JE); La Paz: Lewis 87-606 (MO, PC), 87-385 (LPB); Potosí: Sanjines 4036 (LPB, MO, MUB, USZ).
