Notes     (Last Modified On 4/20/2013)
Blindia contains 16 species widely distributed, in the tropics generally confined to high elevations; three species in the Neotropics. The genus in the tropical Andes is found in high open montane to páramo and puna sties, on rocks associated with streams. Blindia is characterized by the aquatic habitat, restricted to rocks; the rather stiff habit; the short to long oblong upper and median laminal cells; dark red, well differentiated alar cells, pyriform capsules; and smooth, red peristome teeth. When sterile, the genus may be confused with members of the Dicranaceae, but in Blindia the leaf costa in cross-section is mostly composed of undifferentiated cells.
Blindia contiene 16 especies ampliamente distribuidas, en los trópicos generalmente confinadas a grandes elevaciones; tres especies en el Neotrópico. El género en los Andes tropicales se encuentra en zonas abiertas del bosque montano alto hasta el páramo y puna lugares, sobre rocas asociadas con quebradas. Blindia se caracteriza por el hábitat acuático, restringida a rocas; el hábito bastante rígido; las células superiores y mediales de la lámina corto- a largo- oblongas; rojo oscuras, células alares bien diferenciadas, cápsulas piriformes; y dientes del peristoma rojos, lisos. Cuando estéril, el género puede ser confundido con miembros de Dicranaceae, pero en Blindia la costa de la hoja en corte transversal generalmente está compuesta de células indiferenciadas.
Status Unknown for the following two species:
Blindia jamesonii Mont., Syll. 42. 1856. Type: Ecuador. prope Quito, Jameson (PC-Montagne; isotype G). Bartlett and Vitt (1986) exclude this taxon from Blindia; they note that the specimen exhibits crispate leaves, upper cells rounded-quadrate, and capsules oblong-cylindrical.
Blindia sonsoniae Müll. Hal., Linnaea 38: 593. 1874. Type: Colombia. Antioquia, Sonson, 9,000 pedes, 1872, Wallis. The type specimen was collected by G. Wallis near Sonsón (Depto. Antioquia), at 2743 m elevation. The type has not been located (cf. Bartlett & Vitt, 1986), and likely destroyed in 1943 in Berlin. If in fact a species of Blindia, it is likely to be a synonym of B. magellanica.
