syn. nov.
Herzog (1924)
described
P. chiquitensis
on the basis of field observations, but he stated in the protologue that only fragments (parts of an inflorescence,
Herzog 114
) is the
holotype
at L. However, the original description and
type
specimen are insufficient to distinguish the species unambiguously without additional evidence. Thus, on the basis of article 9.7 of the ICBN (
McNeill
et al.
2006
), we hereby designate an epitype.
Paepalanthus chiquitensis
is the most widespread and variable species in section
Diphyomene
, therefore several formerly described species are treated here as synonyms.
Sano (2004)
proposed
Paepalanthus giganteus
as a new name for the later homonym
Paepalanthus
speciosus
(Bong.) Koern. In
the protologue,
Sano (2004)
indicated the collection
Riedel
2300
in LE as the
holotype
of the basionym. However, this material was collected 4 years after the species publication and thus cannot be the
holotype
. As Bongard (1831) did not clearly indicate a type specimen and no original collection belonging to the same species has been found in LE, we consider the original material lost and designate the specimen cited by
Sano (2004)
as a
neotype
for the species.
