The present study was carried out to focus the angiospermic flora of Satchari National Park. The researcher identified a total of 247 species during his one year research period. These have been assigned to 186 genera and 71 families. The families have been arranged according to Cronquist’s system of classification (1981). The ethnobotanical data on 75 species were recorded during field trips from the study area. The study found that the area is also habitat for seven threatened species of Bangladesh.This study was also carried out to identify the threats to present angiospermic flora of the area. The possible conservation measures are suggested for the proper maintenance of the flora of the area.From the present preliminary survey it may be concluded that the Satchari National Park is floristically moderately rich and the home for many medicinal and threatened angiospermic species. To make complete inventory of the area, further long term survey is necessary.
