摘要:
The vascular flora of Ellis Island, a 11.1 hectare (27.5 acre) island in New York Harbor, consists of 247 species within 164 genera and 69 families. The largest families in the flora are the Poaceae (45 species) and Asteraceae (39 species). Twenty five families represented in this flora are comprised exclusively of non-native species. Species of extra-regional origin, 60.3% of the flora, are a major component of the natural vegetation. A list of the 247 species of vascular plants identified is included.
