The spatial variability of soil properties and phytosociological study under different age series plantations of T. grandis at Balaghat (M.P.) was studied. The effect of trees on soil pH and organic carbon is promient under older plantations. Site I (1936) and site II (1948) exhibited better soil properties than site III and IV. Variability of soil pH and org. C in perpendicular transects (N-S and E-W) showed more variations and heterogeneity at site I and site III. Directional variations do not show any definite pattern. Effect of individual tree on soil pH was significant at site II and III but it decrease with distance from main stem , while organic carbon exhibited a significant decrease at site I. Site I and II showed over all more heterogeneity followed by other sites. Phytosociological parameters. Like IVI and coefficient of dominance were higher at site I as compared to other sites. Diversity index value (H) and number of tree soecies were maximum at site II. Species diversity was directly related with soil heterogeneity.

Malignant melanoma is a rare aggressive tumor that originates from melanocytes. Melanomas are most common in the cutaneous region and are rare in the oral cavity. They account for about only 0.5% of all malignant tumors in the oral cavity. Oral Malignant Melanomas may go unnoticed since they are asymptomatic clinically but they are aggressive biologically. In the oral cavity, the hard palate and gingiva are the most common sites of involvement. Melanoma tends to metastasize more faster than other skin cancers. Therefore, early diagnosis of malignant melanoma is necessary. Melanomas that are diagnosed early can be cured with minor surgery and the survival rate and prognosis is better when it is detected earlier. We hereby report a case of a 60-year-old male patient with a complaint of swelling in the gingiva that had diffuse black pigmentation, which was diagnosed as a melanoma.Keywords
