Flowering periodicity and seed germination of Bara bet, Calamus viminalis willd. var. fascicnlatiis Becc.; were studied. It was observed that this species flowers twice in a year i.e. from February to April and again from August to October. Seed ripens after 18 to 22 weeks of flowering. A single plant may yield 2-2.5 kg of fruits in each flowering. A single fruit, on the average, has a diameter of 0.92 cm and weighs o.4og. Seeds germinated after 10 to 18 weeks of sowing. An average of 10 and 26 percent seeds of the first (autumn) and the second (spring) phases of flowering respectively, germinated.
