Dear H S
C. difformis and C. fuscus are two distinct species as per Kew Plant List


It would be good if you inform us about your source as requested by other members also.

Cyperus difformis and C. fuscus are two distinct species, recognised by all prominent Floras

This plant is C. difformis, characterised by globose heads of more than 40 spikes

C. fuscus has much fewer spreading spikes
