Burmeistera fistulosa and B. reclinata, both from the department of Antioquia (Colombia), are here described and illustrated. The first species is similar to B. tomentosula, from which it differs by ...the glabrous surfaces, the petiole 1.4–2 cm long, the lamina elliptic to ovate, the reduced subtending leaves, the calyx lobes 2.5–3.5 x 0.8–1.2 mm, the ventral anthers barbate, and the white, obconic to ellipsoids berries. The second species is similar to B. diazii, from which it differs by the narrowly ovate leaves with 5–6 pairs of secondary veins and higher order veins inconspicuous beneath, the glabrous flowers with calyx lobes 5–9 x 0.6–1 mm, half of the corolla length or less, the barbate ventral anthers, and the white berries suffused with vinaceous lines.
Burmeistera fistulosa y B. reclinata, del departamento de Antioquia (Colombia), son descritas e ilustradas como especies nuevas. La primera de estas especies es similar a B. tomentosula, de la cual difiere por sus superficies glabras, el peciolo 1,4–2 cm largo, la lámina elíptica a ovada, las hojas tectrices reducidas, los lóbulos del cáliz 2,5–3,5 x 0,8–1,2 mm, las anteras ventrales barbadas, y las bayas blancas, obcónicas a elipsoides. Por su parte, B. reclinata es similar a B. diazii, de la cual difiere por las hojas angosto-ovadas con 5–6 pares de venas secundarias y venas de orden mayor inconspicuas por el envés, las flores glabras con lóbulos del cáliz 5–9 x 0,6–1 mm, la mitad del largo de la corola o menos, las anteras ventrales barbadas y las bayas blancas con vetas vináceas.

Based on our ongoing studies of the bryophyte flora of Colombia we report 15 liverwort species new to the country: Archilejeunea nebeliana, Colura calyptrifolia, Dibrachiella auberiana, Fossombronia ...fernandeziensis, Isopaches bicrenatus, Lejeunea angusta, L. concinnula, L. corynantha, L. galeata, L. pulverulenta, L. serpillifolioides, L. tapajosensis, Leptoscyphus hexagonus, Marchesinia languida and Riccia planobiconvexa. Notes are provided on the distribution, habitat and taxonomic differentiation of the species. Lejeunea cochleata is a new synonym of L. angusta, and Taxilejeunea steyermarkii is a new synonym of Lejeunea pulverulenta. With 730 species recorded, in 40 families, Colombia is probably the richest country in liverworts in tropical America.
