Notes     (Last Modified On 10/1/2017)

Ecology: Open montane to páramo and puna, partially shaded to exposed habitats, on soil and occasionally on horizontal tree trunks. Elevation: 1850-5200 m (Colombia: 2620-3400 m, Ecuador: 3300-4000 m, Peru: 1850-4400 m, Bolivia: 3180-5200 m). Distribution: Endemic to the tropical Andes (Colombia to Bolivia).
Bartramia polytrichoides is distinguished by the plant stature to 2.5 cm, erect and appressed leaves to 7 mm, swollen leaf tips, fragile, mostly thin-walled shoulder cells, thin-walled linear leaf base cells, slightly curved setae to 4 mm, capsules to 2.3 mm, finely papillose below, finely striate above exostome, and shorter endostome. The swollen leaf tips of young leaves are diagnostic, older leaves are not unlike B. potosica. The swollen propagula-like structures appear to be a further elaboration of the deciduous leaf tips or limbs of various species in this genus. Bartramia micrangia Herzog, collected by Herzog from Tunari (Bolivia) in 1911, is a synonym.
Bartramia polytrichoides se distingue por la estatura de las plantas que llega hasta 2.5 cm, hojas erectas y adpresas hasta 7 mm, extremos de las hojas engrosados, células del hombro generalmente con paredes delgadas, frágiles, células de la base de las hojas lineares con paredes delgadas, seta escasamente curvada hasta 4 mm, cápsulas hasta 2.3 mm, finamente papilosas en la porción basal, finamente estriadas encima del exostoma, y endostoma corto. Los extremos engrosados de las hojas jóvenes son una característica de diagnóstico, las hojas viejas son similares a B. potosica. Las estructuras engrosadas semejantes a propágulos parecen ser más elaboradas que los extremos o limbos decíduos de varias especies de este. Bartramia micrangia Herzog, colectada por Herzog en Tunari (Bolivia) en 1911, es un sinónimo.
