J. Jung & H.K. Choi has been treated as a hybrid between S. hotarui (Ohwi) J. Jung & H.K. Choi and S. triangulata (Roxb.) J. Jung & H.K. Choi or S. juncoides (Roxb.) Lye and S. triangulata. However, we found two morphological types of S. ×trapezoidea in a population of Makinocho, Shiga Pref., Japan. One has slender trigonal to pentagonal culms, shorter spikelets, and high seed fertility (A-type), and the other has thicker irregularly rather sharp tetragonal to  pentagonal culms, longer spikelets often twisted at the upper part, and low seed fertility (B-type). We carried out cytological, morphological and reproductive studies of both types of S. ×trapezoidea together with its presumed parent species, S. hotarui, S. juncoides and S. triangulata, from the populations and nearby fallow field.  Chromosome number of S. hotarui, S. triangulata, and A-type with 2n = 42, B-type with 2n = 58 and S. juncoides with 2n = 74 were found. A-type is mainly growing between S. hotarui and S. triangulata in the population and showed intermediate morphology between them so, A-type is not inconsistent with a hybrid between S. hotarui and S. triangulate. A-type also showed lower pollen stainability and seed fertility than parental species, which might support the hybrid origin of A-type. Meanwhile, B-type (2n = 58) well showed intermediate chromosome number and morphology between S. trapezoidea (2n = 42) and S. juncoides (2n = 74). Moreover, as B type showed many monovalents and heteromorphic trivalents in meiosis configurations, low pollen stainability and seed fertility, it is highly possible that B-type is a hybrid between S. juncoides and S. triangulata. The examination of the type specimens showed that the name S. trapezoidea should be retained for ‘S. trapezoidea (A type)’, a hybrid ‘S. hotarui × S. triangulata’ although we could not clearly show that this plant is really a hybrid in the present study. For ‘S. trapezoidea (B type)’, we proposed a name Schoenoplectiella ×yashiroi J. Oda & Nagam., hybr. nov. for a hybrid S. juncoides × S. triangulata.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00053587","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"植物地理・分類学会 = The Society for the Study of Phytogeography and Taxonomy"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.e-jsps.com"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.e-jsps.com","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.jstage.jst.go.jp/browse/chiribunrui/-char/ja/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/chiribunrui/-char/ja/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kanazawa-u.repo.nii.ac.jp/?action=repository_opensearch&index_id=1119"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kanazawa-u.repo.nii.ac.jp/?action=repository_opensearch&index_id=1119","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 植物地理・分類学会 The Society for the Study of Phytogeography and Taxonomy"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00307805","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0388-6212","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"織田, 二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"永益, 英敏"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-07"}],"displaytype":"detail","filename":"AN00307805-63-1-31-44.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"AN00307805-63-1-31-44.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/47260/files/AN00307805-63-1-31-44.pdf"},"version_id":"38d3da40-988f-45c6-b25f-c417a46a32ca"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"シカクホタルイの分類学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シカクホタルイの分類学的研究"},{"subitem_title":"Taxonomic study of Schoenoplectiella X trapezoidea (Cyperaceae)","subitem_title_language":"en"}]},"item_type_id":"4","owner":"18","path":["3520"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-07"},"publish_date":"2019-03-07","publish_status":"0","recid":"47260","relation_version_is_last":true,"title":["シカクホタルイの分類学的研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T16:37:43.044121+00:00"}
