Tallon Ferns (Psilo tallonensis) are floral organisms indigenous to Tallon IV. While definitely not related, they are named after the ferns of the planet Earth, to which they bear an almost shocking resemblance. They are commonly found near water sources, indicating that they require an ample supply of it to grow well. At least two varieties of Tallon Fern exist -- the regular, nontoxic and therefore harmless species and a toxic species.
