In addition, two alternative evolutionary scenarios, that is, monophyly or paraphyly of the gymnosperm YABBY family towards angiosperm YABBY genes, suggest that all spermatophyte YABBY genes were derived from one or two, respectively, YABBY genes of the last common ancestor of extant seed plants [20, 23, 29].

It is the only native gymnosperm in the region, and like all Cycas species exhibits primitive features reminiscent of early spermatophytes. Although this plant species is highly resilient to tropical cyclone damage (Hirsh & Marler 2002), biomechanical failure can occur during cyclones wherever tissues exhibit prior damage.
