Malvaceae members in RMNH campus


    The study area Regional Museum of Natural History (RMNH) is an establishment under the Ministry of Environment & forests, Government of India, located on a span of 5.25 acres of land on the northern bank of Karanji tank, , a man made medium sized waterbody. The geographical co –ordinates are 12°18’ 12” N & 76°40’25.52”E. The altitude is about 750 m MSL. The annual rain fall limits to 700 mm. The area falls in the Deccan peninsula with freshwater swamps and tropical secondary scrub jingles bio geographically.

    The regional Museum of Natural History is with a well maintained garden sprawling about 3.25 acres [approx], since its inception in the year 1992, before acquiring and construction of museum building this site was quite dry and barren land. During the past 20 years there is a greater degree of alteration in the land profile and emergence of flora & fauna took place in this vicinity. Being an environmental education centre, this institute adapted a policy to plant native variety of plants, which includes trees, shrubs, creepers, herbs grasses and systematic nursing. This venture attracted a wide array of insects followed by birds and other predators, creating a piece of natural environment pocket. A small patch of land is left for model forest, where plants fed with annual rainfall and the leaf litter compost of their own. In such environment, a number of wild plants [generally regarded as weed flora] are also presented their co existence. This present study is aimed at one such family of plants – MALVACEAE & its cohorts.

So far 22 plants have been identified, belonging to 4 tribes, 12 genera and 22 species have been enlisted.
