“…Up to now, there have been four species reported in China, including L. sinica, L. simplex, L. ramosa and L. crassa, all of which are endemic to China and were identified based on morphology with no molecular information. These four species have numerous characteristics in common with each other and L. manipurensis, and all five species are from Asia [4]. According to the morphological comparison listed in Table 1, the newly recorded L. manipurensis was similar to L. sinica and L. crassa in thallus height, while the thallus was obviously larger than that of L. simplex and L. ramose [27].…”

“…There are currently 16 species currently accepted in Algaebase based on traditional morphological identification [3]. Molecular evidence is accessible for only six species: Lemanea borealis Atkinson, L. fluviatilis (L.) C. Agardh, L. fucina Bory, L. manipurensis Ganesan, JA West, Zuccarello, J Rout, L. occidentalis ML Vis and KM Müller and L. condensata Israelson [4]. Species identification for this genus is based on characteristics including thallus height, branch density and spermatangial morphology [5].…”

“…To date, the reports of Lemanea in China have all been based on morphological observations and lack molecular evidence. Thus, they are all regarded as doubtful species [4]. As an important lineage in Rhodophyta, the species diversity and distribution of Lemanea in China needs to be explored further, and their molecular sequences and phylogenetics need to be studied.…”

Morphological and Molecular Phylogenetic Analysis of a Lemanea Specimen (Batrachospermales, Rhodophyta) from China

The genus Lemanea is an evolutionally derived lineage of freshwater Rhodophyta which has a rare distribution. Morphological characterization and molecular phylogenetic analyses were conducted for a Lemanea specimen collected from Guilin, China, in this study. The results based on morphological observation and molecular evidence, including rbcL and SSU sequences, showed it was a new record of L. manipurensis Ganesan, West, Zuccarello et Rout in China. The specimen in this study was morphologically characterized by branches that were positioned in the lower part of the thallus, hair cells absent around the outer cortex, ellipsoidal and single carpospores at the top of the gonimoblast filaments and spermatangia formed in continuous wide rings on the thallus nodes. By comparing the morphology of specimens collected from Guilin, China, and the holotype specimen in India, it was found that the spermatangial shapes were variable among different populations. It was found that the presence or absence of hair cells around the outer cortex was not a reliable characteristic for the identification of the genus Lemanea based on a comparison between L. manipurensis collected in Guangxi and in India and another four Lemanea species previously recorded in China. The results of this study provided molecular evidence and a theoretical basis for molecular phylogenetic research on the genus Lemanea and enriched the species diversity and geographical distribution of Lemanea in China.
