Micrococca mercurialis ( Linn. ) Benth (Euphorbiaceae) cited as CaloxyIon mercurialis Thwaites by Hooker ( 1887) was reported by the same author as occurring at Mongir of Behar, the Deccan Peninsula, Burma and Ceylon. It is distributed in Arabia and tropical Africa. Prain ( 1903) reported it from Behar. This species has recently been collected from Chittagong district. In the various floristic works by Heining ( 1925 ), Raizada ( 1941 ), Datta and Mitra ( 1953), Sinclair ( 1955) and Khan and Banu ( 1972) the species has not been recorded from the region now under Bangladesh.

Land capability evaluation for soils ofthe High Terraces (Madhupur Tract) and of the Tertiary Hills has been done according to FAO’s framework for land evaluation. Parametric limitation indices suggested by Sys for use of the FAO system have been followed. General Soil Types were considered as the land units for rating the actual and potential classes based on soil and climatic characteristics as well as the environmental conditions.

Madhupur Tract area has a less favourable climatic condition for growing oilpalm than the northern and eastern hilly areas. Only well to imperfectly drained soils of the Madhupur Tract and of the Tertiary Hills have been found to be suitable to very suitable for growing oilpalm. Frequent flooding on Grey Terrace Soils and on Grey Piedmont Soils have been considered as a serious limitation for this crop. Occasionally flooded Grey Terrace Soils, Grey Piedmont Soils and the steeply sloping (> 30%) Brown Hill Soils have been rated as marginally suitable for this crop.

A root rot disease of Gamar (Gmelina arborea Linn.) in forest nursery is reported. A review of the literature is provided. The symptoms of the disease and the extent of damage have been described. Four fungi were isolated from diseased seedlings. Fusarium solani ( Mart. ) Sacc. has been found to be responsible for the root rot. The disease was practically controlled by a single application of the fungicide Granosan M, at the rate of 8g per 9L of water. The fungicide was applied as a soil drench on to areas of soil surrounding dead, dying and healthy seedlings.
