The paper throws light on traditional and experimental gardens and discusses their role in preservation and protection of valuable plant resources with special reference to the Experimental Garden at Barapani in Meghalaya.

The present paper provides a glimpse on the botanical aspect and the floristic diversity of the Singalila National Park, Darjeeling district, West Bengal along with the existing threats to its flora. Dominant families and genera are listed in Table 1 to 2 for dicotyledonous and monocotyledonous flora.

Panna National Park lies in Vindhyan hill ranges of Madhya Pradesh between 24º 27' to 24º 46' North latitudes and 71º 45' to 80º 90' East longitudes, covering an area of 478.81 sq. km. The present paper deals with the topography, geology, climate, rainfall and soil in general. Floris-tically, the present investigation is primarily based on 3 years extensive tours undertaken in different seasons along with available herbarium data in BSA, BSD and CAL; critical investi-gation of these resulted in to 609 species under 394 genera and 108 families. The vegetation of the area is discussed along with seasonal vegetation, hydophytic vegetation, vegetation of special habitats and weeds of Kharif and Rabi crops. A separate chapter deals with interaction of plants and animals and their favourable habitat and also plant species used as staple food by different animals of Panna National Park. Economic aspects of the flora, viz. cultivated crops, vegetable plants, fruit yielding plants, ornamental plants, wild edible plants, timber yielding plants, fibre yielding plants, tannin and gum yielding plants and medicinal plants have been dealt briefly. Conservational aspect of the flora has also been discussed in brief for the benefit of policy makers, foresters and other plant managers.

A detailed survey on the floristic diversity of the Barda Hills and their surroundings has been carried out with Thaker’s (1910) treatise as the standard starting point with respect to the plant species composition, the disappearance of species and the newly entered species. The survey brought to light a total of 907  plant species (both indigenous and introduced) belonging to 512 genera of 116 families. Out of these, dicots accounts for 730 species, monocots 169 species, 3 gymnosperm and 5 pteridophytes. An occurrence of some 315 sp. (new records from the area) not enumerated by Thaker (l.c.) from the area (net gain to the floristic list by 46.0%) has been listed. The study also highlights a loss of some 92 sp. (13.4%) from the hitherto record of 684 floristic species by Thaker (1910) and addition of 22 species made to the Flora of Saurashtra out of which one is new to Gujarat. (Map 1 and 3 tables).

The present paper deals with 197 vascular taxa belonging to 152 under 64 families, including 15 species of ferns. Besides the vegetation account and rare & threatened species, enumeration of taxa collected from the area have also been dealt with phenology, habitats and place of occurrence.

Orang National Park is one of the protected areas of Assam and embraces an extremely rich floristic diversity of several plant species of botanical interest and an enormous economic potential. The present paper deals with 96 species of economically important plants of park. Of these, 55 are medicinal, 24 edible, 15 timber yielding, 20 fodder resources, 5 fiber yielding, 6 used for thatching, 3 dye-yielding, 8 provide plywood and 2 spp. tannins. It also highlights the various threats and conservation measures of the rich florisitic wealth of the park.
