Peridictyon is a genus of grass with a single species, Peridictyon sanctum, native to southern Bulgaria and northern Greece.[3]
Taxonomy
When the genus name Peridictyon was published in 1991, the authors cited the type as the combinatio novaPeridictyon sanctum (Janka) Seberg, Fred. & Baden, based on Festuca sancta Janka.[3] The description provided in the original publication of F. sancta includes remarks about finding the species, and describes a few of its features, but does not list any characters that would distinguish it from other species in the genus Festuca.[4] The Index Nominum Genericorum has judged this to mean that Festuca sancta was a nomen nudum, and hence Peridictyon was not a validly published name.[5] Other sources disagree; the International Plant Names Index states that the descriptive characters given are sufficient for the publication of the species name Festuca sancta.[6]
