Ten species of paramecia have been recorded up to the present , but there has been no report on paramecium in Korea. With the purpose of taxonomical study, paramecia were collected as materials at the several areas(ponds and streams) in Seoul from the first of March to the late of October , 1962. From the characteristics of the body-shape and the type and number of micronuclei, the six unrecorded species are identified on this paper as follows : Paramecium caudatum P.aurelia P.multimicromucleaturm P.bursaria P.trichium P.calkinsi

Vulpia octoflora (Walter) Rydb., a newly identified invasive alien species, was found in Gangcheon-ri, Yeoju-si, Gyeonggi-do, South Korea. It is native to North America and has been reported to be an invasive alien plant in Japan, Australia, and Ukraine. Vulpia octoflora is a weed that grows mainly in dry sandy or rocky soil and is frequently found along the roadside in open areas or in artificially disturbed sites. This species is similar to the recently confirmed alert alien species, V. bromoides (L.) Gray, but is readily distinguishable due to more florets per spikelet and a short awn of the lemma. A detailed species description, the geographical distribution, illustrations, photographs, and an identification key for all species of Vulpia that occur in Korea are provided.
