Family Grimmiaceae is found in xeric to wet conditions, grows mostly on basic to neutral substrates rarely on acidic, the members of this family are mostly lithophytes. Initially the relevant available literature the topic and Pakistan was reviewed. After literature survey, field plane was chalked out. Extensive field trips were arranged in different seasons from 2014-2016, from 400-5000 m elevation. From each locality, specimens of desired family were collected. Relevant information i.e. Habitat, substrate, GPS coordinates etc. were recorded on field, while morphological and anatomical studies were carried out in Lab. identification was carried out by consulting different relevant Floras. Previously, there are 18 taxa and 2 genera have been reported from Pakistan, 6 species and 2 genera have been reported from the study area. Currently 7 species and 2 genera have been collected from study area. Among these, 1 species is new record for Pakistan.
