Asplenium castaneo-viride, A. × uiryeongse, A. × montanus, and A. × kitazawae share several morphological characteristics with the Asian walking fern A. ruprechtii and related taxa as parents and show a sympatric distribution with the putative parents, raising the possibility of hybrid origins: A. castaneo-viride (A. ruprechtii and A. incisum), A. × uiryeongse (A. ruprechtii and A. pekinense), A. × montanus (A. ruprechtii, A. trichomanes, and A. incisum), and A. × kitazawae (A. ruprechtii and A. sarelii). We investigated flow cytometry and chloroplast DNA sequence data (rbcL, rps4-trnS, and rps4-trnS intergenic spacer) to clarify the hybridization and origin of each hybrid. In the flow cytometry analyses, A. ruprechtii shows diploid (2x) only, whereas A. castaneo-viride (3x, 4x), A. × uiryeongse (3x), A. × montanus (3x, 4x), and A. × kitazawae (2x, 4x) exhibit polyploidy, suggesting hybrid events along speciation. The rbcL and rps4-trnS and rps4-trnS intergenic spacer data suggest that A. ruprechtii is one the maternal ancestors of all four hybrids. In addition, the rps4-trnS and rps4-trnS intergenic spacer data indicate that A. incisum is also the maternal ancestor of A. × kitazawae and A. × montanus, proposing multiple hybridization events for these two hybrids. In A. × montanus, morphological features such as the leaf forms and sympatric distributions of the species also support the multimaternal hypothesis, but the morphological features of A. × kitazawae must be examined with consideration of hybrid events. To clarify the complex hybrid evolutionary lineages of the four Asplenium hybrids, further research with taxon sampling and molecular markers should be conducted.","PeriodicalId":52232,"journal":{"name":"KOREAN JOURNAL OF PLANT TAXONOMY","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47829320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

P. × bohyeonsanensis and P. × seoraksanensis share several characteristics (trichome on the sepal margin and midvein, five petals, and stem reclining to the ground after flowering) with P. davidii. P. × bohyeonsanensis, resulting from natural hybridization of P. davidii and P. okamotoi var. longipedicellata, has sterile fruit and a long pedicel (2.2–6.0 cm). P. × seoraksanensis, a natural hybrid of P. davidii and P. palibiniana var. palibiniana, has sterile fruit and a short pedicel (1.1–1.8 cm). P. okamotoi var. longipedicellata shares several characteristics (long pedicels of chasmogamic flowers that elongate to the ground when bearing fruit and cleistogamic flowers with a long pedicel) with the related taxa P. okamotoi var. okamotoi. P. okamotoi var. longipedicellata has slender root tubers, glabrous pedicels, and 5–9 petals. P. palibiniana var. gageodoensis is described from Gageodo Island. It is similar to P. palibiniana var. palibiniana having chasmogamic flowers at the stem terminal, 5–7 petals, and a short pedicel, but P. palibiniana var. gageodoensis is distinguished by 1–2 rows of trichomes on the pedicel, a large sepal size, a large petal size, and a branched stem at its base. P. × biseulsanensis, from a natural hybrid of P. heterophylla and P. okamotoi var. longipedicellata, has a solitary aerial stem, a chasmogamic flower at the stem terminal, a shallow marginate or bitten petal apex, one row of trichomes on the pedicel, and sterile fruit. P. × segeolsanensis, from a natural hybrid of P. palibiniana var. palibiniana and P. okamotoi var. okamotoi, is described from Segeolsan Mt. It has numerous aerial stems, a chasmogamic flower at the stem terminal, 1–2 rows of trichomes on the pedicel, and fertile fruit.

Blume [C. erecta var. subaphylla (Miyabe & Kudo) Ohwi and C. erecta f. subaphylla (Miyabe & Kudo) M. Hiro]. Allozyme markers, traditionally employed for delimiting species boundaries, are used here to gain information for determining the taxonomic status of C. subaphylla. To do this, we sampled three populations of five taxa (a total of 15 populations) of Cephalanthera native to the Korean Peninsula [C. erecta, C. falcata (Thunb.) Blume, C. longibracteata Blume, C. longifolia (L.) Fritsch, and C. subaphylla]. Among 20 putative loci resolved, three were monomorphic (Dia-2, Pgi-1, and Tpi-1) across the five species. Apart from C. longibracteata, there was no allozyme variation within the remaining four species. Of the 51 alleles harbored by these 17 polymorphic loci, each of the 27 alleles at 14 loci was unique to a single species. Accordingly, we found low average values of Nei’s genetic identities (I) between ten species pairs (from I = 0.250 for C. erecta versus C. longifolia to I = 0.603 for C. falcata vs. C. longibracteata), with C. subaphylla being genetically clearly differentiated from the other species (from I = 0.349 for C. subaphylla vs. C. longifolia to 0.400 for C. subaphylla vs. C. falcata). These results clearly indicate that C. subaphylla is not genetically related to any of the other taxa of Cephalanthera that are native to the Korean Peninsula, including C. erecta. In a principal coordinate analysis (PCoA), C. subaphylla was positioned distant not only from C. falcata, C. longibracteata, and C. longifolia, but also from C. erecta. Finally, K = 5 was the best clustering scheme using a Bayesian approach, with five clusters precisely corresponding to the five taxa. Thus, our allozyme results strongly suggest that C. subaphylla merits the rank of species.","PeriodicalId":52232,"journal":{"name":"KOREAN JOURNAL OF PLANT TAXONOMY","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44902850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen samples from the six species are tricolporate, and the colpi are surrounded by broad margo, with the widest width in the equator, narrower toward the pole, and rounded at the end. Based on the pollen morphology, pollen of the species in the subtribe Neoguillauminiinae were divided into four types: the Neoguillauminia type (T1), the C. collinus type (T2), the C. casuarinoides type (T3) and the C. paucifolius type (T4). The generic divergence between Neoguillauminia and Calycopeplus was supported by the pollen characters of the size, amb and lumina shape. In particular, the traits of rounded shape in the outline of the polar view and circular lumina, which appear only in the pollen grains of N. cleopatra, support the recognition of Neoguillauminia as a monotypic genus. Calycopeplus oligandrus and C. paucifolius had the same reticulate pattern of pollen grains, supporting Forster’s hypothesis that these two species are closely related. On the other hand, the close relationship between the morphologically similar C. collinus and C. casuarinoides was not supported by the pollen characters. Within the subtribe there are two equally parsimonious hypotheses regarding the evolution of exine characters. The first consists of two changes of microreticulate through parallel evolution from the primitive reticulate exine, and the second is that the microreticulate pattern is differentiated from the reticulate state and then reversed to reticulate pollen grains.","PeriodicalId":52232,"journal":{"name":"KOREAN JOURNAL OF PLANT TAXONOMY","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46308152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
