The arrival of radfauna did more than enough to alter the shape of the ecologies of Dingus, as the local flora, both piss and pisscake-based, must face a novel pressure on the continent: regular exposure to concentrated radiation, albeit not enough to be totally lethal. Fortunately, thanks to the advent of sexual reproduction in both floral lines, adapting to these peculiar conditions is ensured more than ever. Of the Nomherb line, the Plumbush arose.
At first glance, the Plumbush is a fairly typical shrubby organism - possessing a lignaceous trunk leading to copious branches, which in turn terminate into dense leafage. The most significant change to its biology however is much less obvious: it can incorporate lead from the environment into its tissues, protecting it from the background radiation emitted by radiofauna! To ensure it doesn’t die from incorporating such heavy metals, the Plumbush’s tissues have developed considerable resistance to it as well.
Like their ancestry, Plumbushes send out gametes into the wind which meet receptive individual flora to form spores. Said spores are reinforced within a radiation-resistant, seed-like outer hull, which will germinate into a new organism once it finds a suitable location to situate in, preferably with abundant lead.
Although found throughout much of Dingus’s more humid climates, their proliferation is not enough to totally replace the ancestral Nomherb, as both flora occupy different niches. Lead concentrations are at their greatest among populations that are found where radfauna are most abundant; conversely, where radfauna are scarce, Plumbushes tend to incorporate very little lead to none.
