* Euastrum binale var. curtum (West & G.S. West) Willi Krieger

Comments: Its basionym is Euastrum cosmarioides var. curtum W.West & G.S.West. This is likely a nascent form of the type variety due to rapidly dividing cells.

Distribution: A new varietal record for Kalimantan, previously reported from Singapore and Angola ( Krieger 1937).
