摘要:

The differentiation ofCallitriche hermaphroditicain Sweden expressed in fruit morphology has been studied. Variation among 50 wild‐scored populations is illustrated by canonical variates analysis and cluster analysis and shown to be geographically correlated. Two major geographical races differing in fruit size are distinguished and confirmed by the study of herbarium collections. The anatomy of the fruits is described, based on light microscopical studies. An anatomically aberrant fruit form was found in two different areas in Sweden. Comparisons are made with herbarium collections from Denmark, Norway, Finland and Soviet Karelia. The biogeography, in the light of postglacial events, and the taxonomy ofC. hermaphroditicaare discussed and a distribution map ofC. hermaphroditicas. lat. in Sweden is presente

摘要:

Epidermal characters provide additional features in the assessment of taxonomic relationships among the European species ofAntirrhinum.Much of this study confirms the classification derived by Webb but important differences have been observed, viz.A. mollissimummay be considered as identical toA. mollewhilstA. boissieri, A. ambiguumandA. rupestremay be assigned as distinct species. Evidence from epidermal characters supports Rothmaler's view thatA. majusspp.litigiosumis a subspecies ofA. majusand should not be amalgamated withA. barrelierias proposed by Webb.A. × huteriis proposed to be a hybrid betweenA. hispanicumandA. boissieri.Thus it is proposed that the sectionAntirrhinumcomprises 20 species withA. majusdivided into five subspecies
