Abstract: Four newly recorded species were reported as new records of Tibet，Peristylusbulleyi，Sedumtrichospermum，DrabanemorosaandSinocrassulaindica.Statistics of new species distribution groups showed that their distribution habitats were basically the same as the records，but the distribution altitude different from the record. The results showed that they had stronger ecological adaptability and wider distribution ecological amplitude，significant for researching of the Tibetan plants diversity and abundance. The voucher specimens were deposited in Tibet Plateau Ecological Research Institute（XZE）.

Key words: Tibet, Peristylusbulleyi, Sedumtrichospermum, Drabanemorosa, Sinocrassulaindica, new record
