Somlyay, L.: Occurrence of Chamaesyce glyptosperma, and a survey of the genus Chamaesyce (Euphorbiaceae) in Hungary

26 L. Somlyay C. glyptosperma is a rare alien in the flora of Europe, introduced most probably from America (HÜGIN 1998, FISCHER et al. 2005). Until now, in Europe it was collected only at a few localities in Austria, France, Italy, Republic of Macedonia and Switzerland (reviewed by HÜGIN & STARLINGER 1998 and HÜGIN 1999), though the Swiss record could not be confirmed by RÖTHLISBERGER (2007). Notes on Chamaesyce species recorded in Hungary C. canescens (LINNAEUS) PROKHANOV, 1933 (syn.: Euphorbia chamaesyce LINNAEUS, 1953) Remarks - A species named "Euphorbia chamaesyce

" was reported only once from the botanical garden of Vácrátót (Pest county, north Hungary), where the escape of it (though inside the garden) was observed (PRISZTER 1985: 48), but voucher specimens are not available. However, due to erroneous synonymy, in BALOGH et al. (2004) this record was mentioned as C. prostrata (AlTON) SMALL, 1903. In fact, neither C. canescens nor C. prostrata was collected in present-day Hungary so far. Although the Hungarian occurrence of C. canescens can not be excluded, the above record is more than doubtful. It should be noted that in some cases the binomen "Euphorbia chamaesyce

" was erroneously applied to C. maculata and C. humifusa specimens (BP) by Hungarian collectors. C. humifusa (WlLLDENOW) PROKHANOV, 1927 (syn.: Euphorbia humifusa WlLLDENOW, 1814) Herbarium specimens - "
