Chamaesyce nutans (Lag.) Small (Euphorbiaceae) and Eleusine indica (L.) Gaertner (Poaceae) are described as new records for the flora of Lebanon. Specimens of C. nutans collected from roadsides and rocks in a middle mountain forest confirm the occurrence of the species on the western slopes of the Mount Lebanon Range. | Turk J Bot 31 (2007) 341-343 © TÜB‹TAK Research Note Two New Records from Lebanon: Chamaesyce nutans (Lag.)

Small (Euphorbiaceae) and Eleusine indica (L.) Gaertner (Poaceae) are described as new records for the flora of Lebanon. Specimens of C. nutans collected from roadsides and rocks in a middle mountain forest confirm the occurrence of the species on the western slopes of the Mount Lebanon Range. Additionally, specimens of E. indica were collected from wasteland and roadsides in the coastal town of Kaslik. The species were observed to thrive abundantly in similar habitats along the coastal urban zone of Lebanon. Key Words: Adventitious species, biodiversity, Euphorbiaceae, flora, Gramineae, Lebanon, Mediterranean, Poaceae Introduction Chamaesyce nutans is (Lag.) Small established in many countries of the European continent, particularly in the central and southern regions, where it is described to occur as a locally naturalised species (Smith & Tutin, 1968). In the neighbouring region, C. nutans is reported from Palestine, where it is uncommonly encountered in nurseries and waste places in the Judean Mountains (Zohary, 1972). The Flora of Turkey does not indicate any reference to the presence of the species (RadcliffeSmith, 1982). Similarly, C. nutans has never been reported from Lebanon or Syria (Post, 1932; Mouterde, 1970). Eleusine indica (L.) Gaertner is generally considered an adventitious species originally native to the tropical and subtropical regions (Hansen, 1980; Tan, 1985; FeinbrunDonthan, 1986). In southern Europe it represents a naturalised species occupying roadsides and disturbed grounds (Hansen, 1980). It is the only species of the genus that has established .
