  • Malvastrum coromandelianum

    Malvastrum coromandelianum (L.) Garcke (Am.) – A very rare and ephemeral grain alien. Recorded for the first time in 1996 in a dump in Rumbeke-Roeselare. Subsequently seen in 2000 on a birdseed dump in Willebroek. Also grown from soybean waste and, probably from the same source, also seen on levelled soil in Bilzen in 2017. Recently found in a bulb field in the Netherlands (Holverda & al. 2009, Reijerse & Verrijdt 2010).

    This species much resembles Sida spinosa in general appearance. However, Malvastrum coromandelianum is readily distinguished by the presence of an epicalyx that is lacking in Sida spinosa.
