However, Aechmea mulfordii is a large terrestrial plant , growing near the sea level on sand dunes . Aechmea mulfordii has leathery green leaves ligulate or sword shaped. The leaves may grow to 1 m 3ft in length, at times much less, and form a central vase, which, in cultivation, should be kept filled with water. On this species, the primary bract greatly exceeds the lowermost branch. The flower spikes sent up from the heart or crown of the plant are red panicle with the three outer sepaloid segments longer than the three inner or petaloid ones. Frequently confused with Aechmea rubens A. rubens and Aechmea emmerichiae A. emmerichiae , A. mulfordii has less dense and elaborate inflorescence than A. rubens and the long, broad floral bracts conceal the ovary. Mythology The name of the genus Aechmea has been given by taxonomists because of the characteristically sharp points of the sepal s and of the bract s covering the flower buds.
