Notes onCarex (Cyperaceae) from China (IV). the identity and revision of sect.Infossae
摘要
Abstract
Carex sect.Infossae S. W. Su was recently described from Anhui and Jiangsu provinces of East China, containing two species with one variety:C. infossa var.infossa,C. infossavar.extensaandC. minuticulmis. According to the sectional description,fifteen additional species and two varieties should be placed in this section. Based upon lit-erature survey,specimen examination,field work,and SEM observation of perigynia and achenes,a concise table of different treatments betweenFlorae Reipublicae Popularis Sinicae andFlora of China was provided,as well as the morphological characters distinguishing these taxa and micromorphology of perigynia and achenes for the selected taxa were compared. Among the diagnostic characters,arrangement of spikes and perigynium indumentum are inseparable from each other,and two species in sect.Infossae are consequently recognized in the present paper. Carex elmeri,C. granifera,C. minuticulmis,C. shanghaiensis,C. blinii subsp.shanghaiensis,C. sublateralis,C. taihokuensis andC. tatsutakensis were synonymized toC. blinii.Carex canaliculata,C. changmuensis,C. distantiflora,C. infossa,C. infossa var.extensa,C. lateralis,C. loheri,C. longerostrata var.exaristata,C. longerostrata var.hoi,C. lyi,C. macrandrolepis, C. sharyotensis were reduced as synonyms toC. oxyphylla.关键词
