Eragrostis cilianensis

1. Eragrostis cilianensis (All.) Vign.-Lut. ex Janchen (syn.: E. major Host, E. megastachya (Koeler) Link) (trop. and warm-temp. regions of the Old World) – A regular but ephemeral alien, sometimes persisting for some years but not really becoming naturalised. Apparently first collected in 1824. At present primarily introduced with grains, formerly also a common wool alien. Usually found in port-areas, especially near granaries, unloading quays, under grain elevators, by motorways, in urban areas (often where birds are fed), etc.

The Belgian populations are fairly variable (see also Tsvelev 1984). Typical plants are readily distinguished from Eragrostis minor but certain forms (especially poor- or small-flowered forms) show more or less intermediate diacritic features and are often hardly distinguished.
