ABSTRACT
The aquatic and marshland vegetation of Baksa district is quite rich due to presence of a large number of water
bodies. The study reveals that various parts of 41 species are edible and consumed by the tribal and non-tribal
communities inhabiting there in. These plants belong to 33 genera and 24 families. Among these plants, 27 species
belong to dicot and 14 to monocot. The medicinal and other uses of plants are also reported.
Key words: Aquatic, marshland, Baksa district, Bodo

INTRODUCTION
Baksa is one of the four districts of BTC area. It is located in the north bank of river Brahmaputra in Assam. The
district is bounded by Bhutan in the north, Udalguri district in the east, Barpeta, Nalbari and Kamrup districts in the
South and Chirang district in the west. The total area of the district is 2400 sq Km and population density is 475/sq
Km. Geographically Baksa district is located between 26o30/ to 26o45/ N latitude and 91o10/ to 91o45/ E longitude.
Many perennial water reservoirs such as rivers, beels, jheels and swamps are observed here. Again monsoonal rains
make temporary marshy depressions in and around paddy fields and forest area. All these provide an ideal luxuriant
growth of aquatic and marshland angiosperm. Aquatic plants are those plants whose seeds germinate in either the
water phase or the substrate of a body of water and which must spend part of their life cycle in water [1]. The
aquatic plants, according to habitat category, may be rooted floating, free floating, submerged, rooted emergent and
wetland hydrophytes [2, 3]. Some of the wetlands in this district are Barkharua, Roumari, Charan Beel, Potapather
Beel, Dangapather Beel etc.
The population of Baksa district is 953773(census report, 2011). The communities inhabiting there in are Bodo,
Assamese, Adivasis and Rabha [4]. The region is inhabited predominantly by Bodo speaking ethnic group. The
aquatic plants constitute a significant components of diet among the Bodo people of Baksa district. The tribe Bodo
has been selecting wild aquatic plants as a suitable source of food since ancient times. The Bodo community of
Baksa district has vast knowledge on ethnobotany [4, 5].
MATERIALS AND METHODS
The specimens have been collected at their flowering and fruiting stages at regular intervals covering all the seasons
of the year (during 2011-2012). Herbarium sheets (42cm X 28cm) have been prepared following procedures of [6].

All the information regarding vernacular names, edible plant parts, other plant parts used, mode of utilization were
collected from different persons of different villages of the district. The recorded information are verified and
compared with other informers and also with literature of [7]. The local uses of plant resources of the district have
been analyzed as per the process suggested by [8, 9]. Plants have been identified by comparing herbarium sheets
with those of Gauhati University, Kanjilal Herbarium, Shillong and also by using different monographs and floras of
[10, 11, 12, 13, 14, 15 and16].

CONCLUSION
The present study reports that there are so many edible plants available in the wetlands, paddy fields and other
swampy areas of Baksa district. The Bodo and other communities of the district have been utilizing these plants as
food in daily diet routine. Also some of these plants are used for medicinal and other purposes. Thus they have
traditionally acquired knowledge on these plants. But research in this field, specially in this area is not satisfactory.
Vigorous studies in this field will open a new door on ethno pharmacology and will develop an ethno food hub in
near future. Again it will reduce the unemployment problems and will glorify the economy of the state.
