摘要

Many species of Apiaceae are found in theMacaronesien Region. Several have been introduccdby human activities, but a number oftaxa is endemic to the different archipelagos oreven rrstrictcd to a single island. The followingenumeration is based mainly on HANSEN &SUNDING ( 1993).In the Arores 28 different taxa of Apiaceaeoccur; among them four endemic species[AUIMI; hrrrrii WATSON, A. trifoliatum (WATSON)TKEL., Clrtrc~,y~l~~ll~r~~~ cl:oricrm TREL.. SOErichtrwrictr GUTIINICK ex SEUB.].In Madeira the Apiaceae are very diverseand consist ol’ 29 species and subspecies. Fromthe archipelago two monotypic genera, rC/c/trtio.velitru~rr t/ccipicvr.s (SCHRAD. & J. C.WENDL.) Ho~+hl. md kJorli:ia edu[is LOWEand ~hrcc cndcmic species [Oemmrlre diwricore(R. BR.) MABB.. I/nperrr/orio lotvei COSS.and Burrirr~r hre~$~lirrnr LOWE] are described.The Canary Islands have the highest numbcrof plant-species and a high level of endemism.5-l taxa of Apiaceae are recordedincluding three endemic genera (RtrrheopsisA. HANSEX & KUNKEL, Todm-oa PARL. andTiqyrmm PARL.) and further I5 endemic taxa.The Apiaceae are represented in the CapeVerde Islands by I2 species. Most of the taxa have been introduced by human activities(LOBIN & ZIZKA 1957) like Amvhm grm’eo-1efr.s L., Apirm grmvolerrs L, Foerricrrhrr urlgoreMILL.. Corimrtlru~t~ srrtirvrrrr L. or Petrosilerrmcrisprrm (FRILL.) A.W.HILL. Thesespecies are cultivated and some of them laterbecame esdy. Other species like Ciclosper-UWL /e/~fo/~/l~ll~rrtr (PER%) SPRAGUE (= Apimrleproplr~llrr~rr) are weeds of cultivated groundsor wasted lands. All these species are todaywidespread in temperate. subtropical or tropicalregions all over the world. The only nativespecies are to be found in the endemic genusTo~wI~~I~~~ PARL.
