Sparganium coreanum, a barely recognized species in Korea, was rediscovered during a field survey by the authors, who conducted a re-examination of specimens deposited in the Herbarium of the Korea National Arboretum (KH). This species was described initially by H. Leveille from a specimen collected by F. Taquet from Jeju-do (Taquet 2150). Subsequently, however, it was overlooked and unrecognized among South Korean flora. Several populations of S. coreanum were found in the southern part of the Korean Peninsula and on Jeju-do, although it has long been recognized as S. erectum owing to certain vegetative morphological characteristics shared between the two species, such as robust stems, a similar plant height, and globose rhizomes. However, it is distinct from S. erectum by the number of female heads on the lowest inflorescence branch and the size and shape of the fruit. In this study, we provide a detailed description, illustrations, and photographs with a revised taxonomic key for identification of Sparganium species in Korea.

Viburnum in Korea includes ten species. The phylogenetic relationships and morphology of the genus Viburnum in general have been studied substantially for the past three decades. A clear understanding of the systematic relationships and an assessment of the level of morphological variation of these plants distributed in Korea are lacking. This study investigated the morphology of these species using herbarium specimens and fresh materials obtained during fieldwork to examine the morphological variation level for a better understanding of each species in the genus. A comparative analysis showed that the species of Viburnum in Korea are easily distinguishable based on various characters of the bud, leaf, extrafloral nectary, inflorescence, corolla, fruit, and stone.

The purported four hybrid origins of Asplenium in Korea were tested based on morphological, cytological and DNA sequence data. 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.
在形态学、细胞学和DNA序列数据的基础上，对韩国的四个杂种起源进行了测试。astplenium castanoe -viride、a . x uiryeongse、a . x montanus和a . x kitazawae与亚洲行走蕨类a . ruprechtii及其相关类群具有相同的形态特征，并与推定的亲本具有同域分布，提出了杂交起源的可能性;绿斑姬斑姬螨(A. ruprechtii and A. incisum)、乌林英斑姬螨(A. ruprechtii and A. pekinense)、山斑姬螨(A. ruprechtii、A. trichomanes和A. incisum)、北泽斑姬螨(A. ruprechtii and A. sarelii)。我们利用流式细胞术和叶绿体DNA序列数据(rbcL、rps4-trnS和rps4-trnS基因间间隔)来澄清每个杂种的杂交和起源。在流式细胞术分析中，A. ruprechtii仅表现为二倍体(2x)，而A. castanee -viride (3x, 4x)、A. x uiryeongse (3x)、A. x montanus (3x, 4x)和A. x kitazawae (2x, 4x)表现为多倍体，表明在物种形成过程中存在杂交事件。rbcL、rps4-trnS和rps4-trnS基因间间隔数据表明，鲁氏单胞螨是这4个杂种的母系祖先之一。此外，rps4-trnS和rps4-trnS基因间间隔数据表明，A. incisum也是A. x kitazawae和A. x montanus的母系祖先，说明这两个杂交品种存在多重杂交事件。在A. x montanus中，叶片形态和同域分布等形态特征也支持多母假说，但A. x kitazawae的形态特征必须考虑杂交事件。为明确4个阿斯勒属杂交种复杂的杂交进化谱系，还需进一步进行分类群取样和分子标记研究。

The genus Pseudostellaria (Caryophyllaceae) in Korea was investigated in order to clarify the taxonomic positions and scientific names among the species in this genus based on morphological characteristics. 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. Consequently, the genus Pseudostellaria in Korea has been classified into eight species, four hybrids, two varieties, and five forms.
摘要根据形态特征，对韩国的伪星属(Pseudostellaria)进行了研究，以明确该属各种的分类位置和学名。P. x bohyeonsanensis和P. x seoraksanensis与P. x davidii有几个共同的特征(在萼片边缘和中脉上有毛状体，五个花瓣，开花后茎斜向地面)。P. x bohyeonsanensis是P. davidii和P. okamotoi var. longipedicellata的自然杂交产物，果实不育，花梗长(2.2 ~ 6.0 cm)。P. x seoraksanensis是P. davidii和P. palibiniana var. palibiniana的天然杂交种，果实不育，花梗短(1.1-1.8 cm)。冈本变种长花梗与相关分类群冈本变种有几个共同的特征(裂裂花的长花梗在结果时拉长到地面，闭裂花的长花梗)。长花梗okamotoi变种有纤细的块根，无花梗，5-9瓣。加古多岛的palibiniana var. gageodoensis。它与palibiniana变种palibiniana相似，在茎端有裂裂花，5-7瓣，花梗短，但palibiniana变种gageodoensis的特征是花梗上有1-2行毛状体，萼片大，花瓣大，基部有分枝茎。异叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶假单叶。P. x segeolsanensis是P. palibiniana var. palibiniana和P. okamotoi var. okamotoi的天然杂种，描述于Segeolsan山。它有许多空中茎，茎端有裂裂花，花梗上有1-2行毛状体，果实可育。因此，韩国的Pseudostellaria属被分为8种，4种杂交，2种变种和5种。

The taxonomic rank of the tiny-leaved terrestrial orchid Cephalanthera subaphylla Miyabe & Kudo has been somewhat controversial, as it has been treated as a species or as an infraspecific taxon, under C. erecta (Thunb.) 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.

Hiro]。同工酶标记，传统上用于划分种界，在这里被用来获得信息，以确定葡萄球菌的分类地位。为此，我们采集了原产于朝鲜半岛的头类动物(Cephalanthera) 5个分类群中的3个种群(共15个种群)。直立，C. falcata(拇指)Blume, C. longifolia (L.)Fritsch, and C. subaphylla]。在已确定的20个基因座中，有3个在5个物种中是单态的(Dia-2、Pgi-1和Tpi-1)。除长苞草外，其余4种间均无同工酶变异。在这17个多态位点所包含的51个等位基因中，14个位点的27个等位基因中的每一个都是单一物种所特有的。因此，我们发现10个种对之间Nei’s遗传特性(I)的平均值较低(直立c与长叶c的I = 0.250，镰形c与长苞c的I = 0.603)，而葡萄球菌与其他种的遗传差异明显(葡萄球菌与长叶c的I = 0.349，葡萄球菌与镰形c的I = 0.400)。这些结果清楚地表明，C. subaphylla与包括C. erecta在内的朝鲜半岛原生头类动物的任何其他分类群都没有遗传关系。在主坐标分析(PCoA)中，葡萄球菌不仅与镰刀菌、长苞菌和长叶菌距离较远，而且与直立菌的距离也较远。最后，K = 5是贝叶斯方法的最佳聚类方案，5个聚类精确对应5个分类群。因此，我们的同工酶结果强烈表明，葡萄球菌值得物种的排名。

We report Scutellaria krasevii Kom. & I. Schischk. ex Juz. (subfamily Scutellarioideae, family Lamiaceae) as a new recorded species of Mongolia. This species is morphologically similar to S. galericulata but can be differentiated by the presence of comparatively thick and triangular-cordate leaves having a heteromerously deep-crenate margin, a densely reclinate pubescent stem, and a densely pubescent corolla. A taxonomic description, a key to the genus in Mongolia, habit photographs, and scanning electron photomicrographs of nutlets are provided for species identification. We also present a table for a comparison of the diagnostic characteristics with those of related species. This species grows along the banks of the Unit river, Khutag-Undur soum, Bulgan province, Mongolia, approximately 2,300 km far away from the type locality in Russia.

A new taxon, Viola ramiflora K. O. Yoo (Violaceae), from Jeju-do is described and illustrated. V. ramiflora shares several characteristics (pale purple flowers; triangular-ovate, ovate, or oblong leaf blades; winged petioles) with the related species V. hirtipes, V. japonica, V. phalacrocarpa, and V. seoulensis. However, this new species has branched cleistogamous and chasmogamous peduncles and oblong-ovate cleistogamous bracteoles.

A pollen morphological study was conducted using light and scanning electron microscopy involving six species belonging to the subtribe Neoguillauminiinae. 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.
