In order to clarify occurrence of useful plant species in relation to habitats, a plant inventory and survey were carried out in the Tetepare Island, the largest uninhabited island in the South Pacific was conducted. The number of useful plant species which showed significant distribution bias for a specific habitat was highest in seashore areas, inland areas and riverside areas. The seashore area had many creeping and climbing plants, epiphytic orchid species and epiphytic fern species. The seashore had good conditions of light and moisture compared with other areas. We conclude that the seashore area provides a key habitat for the useful and medicinal plant with species diversity, indicating the importance of these plant resources.

The study was carried out to assess proximate composition and nutrient contents of five medicinal plant species collected from Northwest Pakistan. Bupleurum falcatum and Valeriana officinalis belongs to humid regions, while Forsskalea tenacissima, Lavandula angustifolia and Otostegia limbata belongs to sub-humid regions. Proximate analysis (total protein, fats, carbohydrate, ash, and moisture contents) were carried out following methods of Association of Official Analytical Chemists. Macronutrients (Ca, Mg, Na, K) and micronutrients (Fe, Cu, Pb, Zn, Ni, Cr, Co, Mn) were analyzed using atomic absorption spectrometry. Results revealed higher concentration of macronutrients in F. tenacissima and micronutrients in O. limbata. In conclusion, sub-humid region's species are having higher nutritional value than humid region's species. © 2010 Academic Journals.

Estimated to comprise over 4,500 species of vascular plants, the flora of the Solomon Islands is one of the richest of the South Pacific region. Given the geography and geologic history of the archipelago, the rate of plant species endemism is likely to be high. Despite its diversity and economic potential, however, the flora remains uncatalogued and applied knowledge of its economic value is scant. The Kochi Prefectural Makino Botanical Garden (MBK) has been conducting plant inventory research in the Solomon Islands since 2007, based on a memorandum of agreement (MoA) signed between the Ministry of Forestry of the Solomon Islands and MBK. The aims of the MoA are to facilitate the production of a full plant inventory of the Solomon Islands' flora, and to assess the potential of certain species for development as an economic resource. In the present study, traditional custom doctors, villagers and land owners on Malaita Island were interviewed in a survey of the use of medicinal plants in complementary medicine. Fifty plant species were confirmed as being in regular use. A preliminary checklist to the 163 species cited in the interviews is presented, and detailed descriptions, including vernacular names and uses, of 28 particularly noteworthy species are given.
