Remarks - The first published record of C. humifusa from present-day Hungary comes from SlMONKAI ( 1907), who stated that this Asian species is "not rare in the gardens of Budapest and perhaps in all larger gardens of Hungary as well". However, both vouchers collected by him on the 21st of July, 1906 come from the botanical garden of the Budapest University of Science. Hence, the cited statement of SlMONKAI (1907) is an obvious exaggeration. It is noteworthy that the species under study had already been cultivated in the above-mentioned botanical garden before 1906 (see the specimen of FILARSZKY), therefore the chance of the species' escape from cultivation presented itself. Nevertheless, "Budapest" as a locality of C. humifusa was registered in JÁVORKA (1924-1925). However, contrary to the existence of further specimens (see above) the species was regarded to be extinct from Hungary by JÁVORKA & SOÓ (1951: 472). Later PRISZTER ( 1960) confirmed the presence of C. humifusa in the botanical garden of the Agricultural University (see also PRISZTER 1985: 48). The first (and until now the only) Hungarian report on C. humifusa not relating to garden habitat was published by PRISZTER ( 1960). However, the voucher of this record was revised as C. glyptosperma (see above), hence "Agárd" as a locality of C. humifusa (see SOÓ 1966, 1980, SIMON 2000) must be rejected. C. maculata (LINNAEUS) SMALL, 1903 (syn.: Euphorbia maculata LINNAEUS, 1753) Remarks - The discovery of this species in Hungary is usually ascribed to BÉLA LÁNYI (DEGEN 1

907, TÍMÁR 1

950) who recognised an "alien Euphorbia

" in Szeged (Csongrád county, south Hungary) in 1906 (LÁNYI 1906: 379). In a short time the plant was reported from Budapest (SCHILLER 1917) and gradually became naturalized not only in the capital, but in other regions of Hungary as well (see TLMÁR 1950, SOÓ 1966, PRISZTER 1985). - 7> Annls hist.-nat.
