John Lloyd Williams was an authority on the arctic-alpine flora of Snowdonia during the late nineteenth century when plant collecting was at its height, but unlike other botanists and plant collectors he did not fully pursue the fashionable trend of forming a complete herbarium. His diligent plant-hunting in a comparatively little explored part of Snowdonia led to his discovering a new site for the rare Killarney fern (Trichomanes speciosum), a feat which was considered a major achievement at the time. For most part of the nineteenth century plant distribution, classification and forming herbaria, had been paramount in the learning of botany in Britain resulting in little attention being made to other aspects of the subject. However, towards the end of the century many botanists turned their attention to studying plant physiology, a subject which had advanced significantly in German laboratories. Rivalry between botanists working on similar projects became inevitable in the race to be first in print as Lloyd Williams soon realized when undertaking his major study on the cytology of marine algae.

This paper exhibites species composition and distribution of marine seaweed at 10 sites of Co To and Thanh Lan islands in May 2019. The studies record 76 species of marine algae in the area, belonging to four divisions: Cyanophytes, Rhodophytes, Ochrophytes and Chlorophytes. Among them, five species are classified into Cyanophytes (comprising 6.6% of total species); thirty-four species into Rhodophytes (44.7%); twenty-one species into Ochrophytes/Phaeophytes (27.6%) and sixteen species into Chlorophytes (21.1%). The species composition of marine seaweeds in Co To and Thanh Lan shows significant differences as follows: 22 species (sites number 4 and 10) to 58 species (site number 2) and the average value is 38.7 species per site. Sørensen similarity coefficient fluctuates from 0.33 (sites number 5 and 10) to 0.84 (sites number 1 and 3) and the average value is 0.53. The current investigations show that four species of twenty-one species are collected in the littoral zone and forty-two species in the sub-littoral zone (in which there are thirteen species distributed in both littoral zone and sub-littoral zone). The algal flora in Co To and Thanh Lan is characterized by subtropics.

The revision of the herbarium material, collected in the northern part of the Sea of Okhotsk in 1965–1966 and stored in VNIRO, allowed to expand the taxonomic list of macrophyte algae of the coastal zone of this area. The locations of discovery of 24 previously unmentioned species are described. Myrionema balticum, Ulvella repens, Syncoryne reinkei, Acrochaetium arcuatum were found in the Sea of Okhotsk for the first time. Most species new for the Sea of Okhotsk is represented by epiphytes of the family Ulvellaceae (Chlorophyta). The final taxonomic list of this region, including literature data, consists of 169 species.
