Abstract: | Mountain Yunmeng (37°20′N, 113°54′E) is 1 520m above sea level and part of the Taihang Mountains. With a temperate continental
monsoon climate, the mountain area belongs to the warm temperate deciduous broad-leaved forest region. This thesis was mostly
based on the study of more than 2 000 packages of bryophytes which were mainly collected by the authors in Mt. Yunmeng, Hebei
Province. Of these specimens, there are 36 families, 99 genera, and 244 species (including 17 varieties, 5 formes, and 1 subspecies)
which have been studied and identified. Moreover, it could be seen that Mt. Yunmeng has a diverse population of bryophytes.
The bryoflora could be divided into 10 geographical elements: north temperate element make up the majority, accounting for
52.11% of the entire known bryoflora, and another belongs to the East Asian element, accounting for 19.25%. All temperate
elements, not including 14 endemic to China and 31 Cosmopolitans, were added up to 188 species, which took 88.3% of all the
entire known bryoflora in Mt. Yunmeng. However, there were only 11 Subtropical and Tropical elements. To all appearances,
the bryoflora of Mt. Yunmeng showed obvious temperate characteristics. The authors conclude that the bryoflora in Mt. Yunmeng
belongs to the middle type, between the warm and dry northern mountain area and the warm and damp southern mountain area.
The microclimatic environment greatly influences the bryoflora.
