Abstract
Pleuroblepharis stichidophora gen. et sp. nov., from Amchitka Island
in the Aleutian Island s, is described as new to science. This taxon is the only representative
of the Bonnemaisoniaceae (Nemaliales, Rhodophyta) collected at Amchitka.
It is distinguished from other members of the family by the presence of
macroscopic tetrasporophytes with compound tetrasporangial stichidia arising along
the margins of laminate axes. These tetrasporic branchlets are homologous to indeterminate
branches. Gland cells with brownish contents are present over the surface
of the laminate axes and also on the stichidia . Although numerous specimens
have been collected, tetrasporic plants are the only fertile stages observed so far.
