Vegetative and floral morphologies of the monotypic genus Melocalamus compactifloras (Kurz) Benth. have been described. Detailed morphology of the fruit and seed has also been investigated. Its relationship with Melocatma Trin. and Dinochloa Buse has been established as proposed by Dransfield ( 1981 ).

Keora wood was pulped by steaming the chips under 10 kg/cm² and 7 kg/cm² pressures each for half hour, one hour and one and half hour. The pulps were refined to two different freenesses in each case. Hardboards were made from these pulps without using any sizing materials or additives and tested for strength and water absorption properties. The boards were moderate in strength and water resistance.

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.
