In La Bryoflore du Grand-Duché de Luxembourg an important number of recent bryological records and observations from the Grand-Duchy of Luxembourg are published and commented, concerning 381 new, rare or poorly known taxa for the country since the publication of Koltz's prodrome (1880, 1882). Data from numerous dispersed publications are also integrated. Forty-one distribution maps using a 1 km2 -grid are given. The list of 453 bryophytes – 111 liverworts and 342 mosses – presently known with certitude from the Grand-Duchy of Luxembourg (2587 km2) is established.
