	abstract = {We name and describe two new species, Isoetes jejuensis and I. hallasanensis, from Jeju Island, South Korea. These taxa are compared with related species in East Asia, including I. coreana and I. sinensis. The rugulate megaspore ornamentation of I. jejuensis differs from those other Isoetes species. Furthermore, I. hallasanensis varies from I. asiatica in its microspore ornamentation and chromosome number, although both species have an echinate megaspore ornamentation. These new species are tetraploid (2n = 44), whereas I. coreana is hexaploid (2n = 66).},

	abstract = {Isoetes coreana Chung and Choi is on the list of critically endangered species in South Korea. Using randomly amplified polymorphic DNA (RAPD) markers, we investigated the genetic diversity within and between seven local populations of I. coreana. Ten RAPD primers produced a total of 94 bands, of which 59 (62.8\%) were polymorphic. A low level of genetic diversity was recognized within the populations of I. coreana: polymorphic loci (P), with values ranging from 3.4\% to 33.9\%, and a mean value of 15.5\% being observed. Analysis of molecular variance (AMOVA) showed that genetic diversity was greater among populations (81.6\%) than within populations (19.7\%) or among the three regions included in this study (Han River, Youngsan River, and Nakdong River). In addition, a high degree of genetic differentiation (θB = 0.742) was detected among the populations. These results indicate that genetic differentiation has occurred very rapidly. However, the rate of gene flow between populations was found to be as low as 0.059, irrespective of the genetic and geographical distances between the populations, which indicates that genetic drift must have played an important role in forming the present populations of I. coreana. Because a reduction of genetic diversity as a result of genetic drift is undesirable, increasing the gene flow between populations of Korean quillwort I. coreana should be considered as a conservation strategy. {\textcopyright} 2008 Elsevier B.V.

	abstract = {On the basis of amplified fragment length polymorphism (AFLP) and nucleotide sequence data from nuclear ribosomal internal transcribed spacer (nrITS) and three chloroplast DNA regions (rbcL, cpITS, and trnS-psbC spacer), we investigated the species delimitation and the evolutionary lineage of Iso{\"e}tes asiatica from Hokkaido, Japan. The neighbor-joining (NJ) dendrogram based on AFLP markers revealed the well-defined clusters (bootstrap value = 100\%) of I. asiatica. Results from the principal component analysis are largely congruent with those obtained in the NJ dendrogram. The maximum parsimony analysis, based on data from nrITS and three chloroplast DNA sequences, supported a monophyly of three species, I. asiatica, Iso{\"e}tes echinospora, and Iso{\"e}tes maritima from Hokkaido, Kamchatka, and Alaska regions. The distinct species status of I. asiatica was also well supported in the combined chloroplast DNA phylogeny. Therefore, I. asiatica appear to represent example of gradual speciation due to spatial isolation of ancestral populations followed by genetic divergence. Our results also suggest that I. asiatica is probably not the ancestral diploid of the polyploids occurring in East Asia. {\textcopyright} The Botanical Society of Korea 2009.},

	abstract = {Isoetes L. is critically endangered in areas of East Asia, including Taiwan, Japan, and South Korea. The genetic diversity and the population structure of six Isoetes species from East Asia were evaluated by using amplified fragment length polymorphism (AFLP). Three AFLP-selective primer combinations generated a total 923 amplification products, of which 919 (99.6\%) were polymorphic. The levels of genetic diversity of two diploid species (I. taiwanensis [percentage of polymorphic loci (PPL) = 33.1\%-38.3\%] and I. asiatica [PPL = 49.0\%]) are higher than those of polyploid species (tetraploid: I. jejuensis [PPL = 9.3\%-29.3\%] and I. hallasanensis [PPL = 22.3\%]; hexaploid: I. coreana [PPL = 1.6\%-20.6\%] and I. japonica [PPL = 5.6\%-20.5\%]). Higher genetic differentiation was detected for populations of I. coreana (0B = 0.730) than for the diploid species I. taiwanensis (0B = 0.074). In addition, analysis of molecular variance showed that a large proportion (79.8\%) of genetic differentiation existed among population of I. coreana. However, 93.2\% of the total genetic variation was attributed to differentiation within populations of I. taiwanensis. A neighbor-joining dendrogram resulted in three clusters, one for I. asiatica, one for I. japonica, and one for the rest of the species, subdivided into two: (1) I. taiwanensis/I. jejuensis and (2) I. coreana/I. hallasanensis. Furthermore, individuals from each population of I. coreana and I. jejuensis were clustered into population-specific subclusters. The probable causes of the current pattern of genetic variation and population structure are discussed, and suggestions on the future protection of Isoetes species are also given. {\textcopyright} 2009 by The University of Chicago.
