The genus Cuscuta (Convolvulaceae) in the Andaman Islands with a new record.
Cuscuta campestris Yuncker is recorded as a novum in the Andaman Islands (India). Its habitat was dominated by the association of weeds and adventive species. It has been found that C. campestris is not host specific, but rather habitat specific. The species parasitised every plant which came into contact with it. A new taxonomic key and illustrations is provided to distinguish it from the other species of Cuscuta in the archipelago.
