Notes

The infructescence so strongly recalls a Hypolytrum that Ridley and Gross independently of each other chose the epithet hypolytroides for it.
The male spikelets are inserted laterally, as they are borne from a utriculiform prophyll, and therefore cannot have degraded from an originally terminal position as was supposed by .
Carex hypolytroides is closely related to C. moupinensis Franch.
