摘要

Abstract

Polysiphonia hainanensis

was previously described from Hainan

China

but DNA sequence had never been provided and its phylogenetic position in Polysiphonieae has not been clear so far. The classification of Polysiphonieae has changed recently based on the molecular analyses and detail morphological anatomy

consequently

the generic assignment of some species must be reassessed. In this study

we analyzed phylogenetic relationships of

hainanensis

and the related taxa in Polysiphonieae and Streblocladieae based on

rbc

L sequences

with specimens collected from the type locality and the area around. Two genetic types were detected

and formed a clade with

Bryocladia thyrsigera

with strong bootstrap support

in which the divergence was less than 0.81%. Furthermore

based on morphological analyses

we found characteristics of Chinese specimens

number of pericentral cells

percurrent axis

determinate branchlets

branching pattern

spermatangial axes development

and arrangement of tetrasporangia

etc.

were consistent with those of

Bryocladia

. Combined with morphological and molecular analyses

hainanensis

was taken a synonymous of

thyrsigera

and gametophytes of this species were found from China for the first time.
