Bryoflora Germplasm in Mountain Longtou Natural Reserve of Guizhou Province

The species and flora of bryophyte in Mountain Longtou Natural Reserve of Guizhou Province was investigated in the present work.The results showed that a total of 181 species,which belongs to 93 genera and 45 families(including subspecies,variation and one newly recorded species in Guizhou),were obtained.Interestingly,oligotypic families and oligotypic genera consisted of larger proportion in the families and genera,which accounted for about 57.78%of the whole families and 58.06%of the whole genera.Based on the analysis of geographic elements of species,the geographical elements are complex,13 type of the bryoflora in this region were recognized.Geophytia and Petrophytia are dominant,accounting for about 26% and 23.2%,respectively.The proportion of the tropical elements and that endemic to China were 18.23% and 10.5%,respectively.
