Reproductive shoots dichasial, insect pollinated. Females subtended by cone-scales making up a red cone and consisting of a nucellus enclosed in an integument and another layer derived from two confluent primordia ('calyx and corolla of a flower (generally used when the two are similar).">perianth') with 2 'bracts'; megaspore mother-cell grows into a prothallus without archegonia. Male pollen-bearing structures subtended by cone-scales making up a red cone and consisting of 2 lateral 'bracts' and a 'perianth' formed by the union of 2 bract-like organs, 6 microsporangiophores and a sterile unitegmic ovule; male gametophyte merely a tube-nucleus, an abortive sterile cell and a cell giving rise to 2 sperm nuclei. As pollen tubes penetrate prothallus, prothallial tubes grow up to meet them in the nucellus, fusion of females and males allegedly occurring in the tubes; many zygotes but only one matures and is dispersed with 'perianth' as a wing.
Somewhat challenging in cultivation; appreciating warmth, strong sun, large pots, and more water than might be expected. Never allow soil to dry completely. Propagated by seeds.
previously swapped plants for more mature EEB specimens. New accession number added in 2011.
