Some plant remains from the Tertiary of Hungary

Abstract

The plant remains from the Upper Eocene deposits of Budapest-obuda consist of the following new genera of Euphorbiaceae: Agrostistachyophyllum tomharrisi, Alchorneaephyllum chandleri, Baliosperrnaphyllum kraeuseli and Codiaeophyllum palaeovariegatum. A new combination - Alchorneaephyllum grambasti (Rasky) - is proposed for the leaf remains described previously under the name Sloaneaephyllum grambasti Rasky (1962). Carpolithus alchorneaefarmis sp. nov. is also described from the same locality. From the younger Tertiary tuff deposits at Ipolytarnoc, North Hungary, is identified Omphateaephyllum weylandi gen. et sp. nov. These fossil remains, genera and species show close resemblance with the living members of Crotonoideae group of the Euphorbiaceae (emend. Pax & Hoffmann, 1931).
