In all Africa there is no stranger riddle than the flowering of the land of the Nama. Those bushmen were the first to see their desert land burgeon into a blaze of color. But this paradise was always short-lived; a spectacular bloom that quickly withered away, not to be seen again for many years. RODNEY BORLAND filmed the most recent of these stupendous and mystifying displays. To a landscape already weird with huge halfmens plants, elephant ears and baboons' fingers, suddenly came vast arrays of nodding daisies and wave upon wave of mesembryanthemums, wild geraniums, gladioli and amaryllis. The landscape was bathed in brilliant hues, a natural garden whose glory may not shine again before the end of this century.
