"Diselma archeri" is a dioecious shrub, where male and female cones are located on separate individuals. Both types of cones are very small (3–4 mm) and occur at the branch tips. The female cone is composed of two pairs of opposite cone scales and only the upper pair of scales is fertile. At maturity up to four small winged seeds are produced which are wind dispersed. "D. archeri" seedlings are uncommon as the species often re-sprouts from roots and trunks buried in peat soils.
