“…It is characterized by metallic-purple ventral scales with two filiform appendages and star-shaped female receptacles with 3-5 rounded lobes (Casas 2009). Various species existed in genus Reboulia; however, Boisselier-Dubayle et al (1998) they were merged one species back, demonstrating that variance of morphological differences does not always coincide with genetic differences (Hicks 1992;Oh and Lee 2003;Lee et al 2016): Reboulia queenslandica (Hicks 1992) considered as the second species for a while was confirmed as a polyploid cross between two varieties of R. hemisphaerica (Boisselier-Dubayle et al 1998). The family Aytoniaceae, covering five genera including Reboulia, is third basal group in order Marchantiales next to Marchantiaceae and Dumortieraceae (Villarreal et al 2016).…”

Reboulia hemisphaerica (L.) Raddi is a member of family Aytoniaceae, the third basal group in order Marchantales. Here, we presented complete chloroplast genome of R. hemisphaerica (Genbank accession is MK477551) which is 122,596 bp long and has four subregions: 82,421 bp of large single copy (LSC) and 19,951 bp of small single copy (SSC) regions are separated by 10,112 bp of inverted repeat (IR) regions including 132 genes (87 protein-coding genes, eight rRNAs, and 36 tRNAs). The overall GC content of the chloroplast genome is 28.8% and those in the LSC, SSC, and IR regions are 26.4%, 24.6%, and 42.7%, respectively. Phylogenetic trees with ten chloroplast genomes show phylogenic position of R. hemisphaerica clearly which is clustered with Dumortiera hirsuta. The chloroplast genome will provide high-resolution phylogeny of liverworts in near future. ARTICLE HISTORY

“…Numerous studies have indicated that J. effusus is a prominent component of soil seed banks (Chippindale and Milton 1934, Champness and Morris 1948, Thompson and Grime 1979, Grime et al 1990). The taxonomic characteristics (Lee 2003, Oh andLee 2003) and distribution of J. effusus (Kim and Ko 1980) have been studied in Korea.…”

Juncus effusus is mostly found in freshwater wetlands and is widely used for landscaping and creating artificial wetlands due to its high ecological value. J. effusus tends to dominate during the early stage (3-10 years) of the second succession in abandoned paddy fields. This study focused on the environmental characteristics of J. effusus to create habitat for an endangered species, Nannopya pygmaea, which lives in wetlands dominated by J. effusus. Considering the distribution of J. effusus and N. pygmaea, 63 quadrats at eight wetlands were investigated between May and June 2006 during the critically dry period. Fifty-three species from 28 families co-occurred with J. effusus, and Persicaria thunbergii was the most abundant (63.5%). The optimal ranges of distribution (ORD) for the water variables were water depth, -2 to 10 cm; dissolved oxygen, 0.99-3.55 mg/kg, conductivity ( ; and total carbon, 1.06-2.37%. The appearance of rush during early succession indicated relatively lower levels of these physicochemical parameters, and that ORDs should be maintained for the J. effusus community.
