    A first critical survey of the genus Orthotrichum in Pakistan is provided. The currently known geographical distributions of the species and their ecologies within Pakistan are discussed. The bryophyte collection from Pakistan contains eight species of the genus Orthotrichum. One of these, O. obtusifolium, is reported here for the first time from that country, whilst the occurrence of the other seven species is confirmed. Pseudoleskeella tectorum, associated with O. crenulatum, is also reported here from Pakistan for the first time. Comments on the specimens and a key to allow identification of all eleven species presently known from Pakistan are provided
