Abstract：Bryophytes were collected from four different habitats in Lindai #2 bauxite mine in Zhanjie town, Qingzhen City,Guizhou Province,and the bryophytes with gemmae were statistically analyzed.The result showed that,(1)120 samples were collected from sampling sites,and 10 families,22 genera and 37 species were identified.The dominant species (frequency >10%)were Molendoa japonica Broth (18.72%)and Bryumargenteum Hedw.(11.06%).(2)8 kinds of bryophytes had gemmae,which were attached to Potti-aceae and Bryaceae,accounting for 21.62% of the total.Of these,Molendoajaponica Broth and Bryumar-genteum Hedw.were common bryophytes with gemmae,found in 44 samples and 16 samples respectively. (3)The largest quantities of bryophytes with gemmae were found in areas where rape was cultivated (6 spe-cies);however,frequency was low and there was no dominant species.Additionally,Molendoa japonica Broth.appeared in four different habitats.(4)In summary,bryophytes with gemmae preferred to the rela-tive pollution conditions.(5)The gemmae of Bryumbornholmense Winkelm.&Ruthe.and Bryumapicula-tum Schwagr.occurred on the rhizoids,while other kinds of gemmae were found on the axil which were in the shape of broom.The forms of gemmae were multiple such as sphere,clavate,wooden stick,bud,spin-dle and torch.
