Description:
—
Clarke (1897: 160)
.
Note:
—
Cyperus neocooperi
is very similar to
C. aethiops
, which has smaller glumes and a more northerly, afromontane distribution. Possibly, both could even be considered as conspecific.
Cyperus aethiops
belongs to
Cyperus
section
Pycreus
(
C.
sect.
Polystachyi
Kük.,
nom. illeg.
), and
C. neocooperi
also fits in this group based on its elongated elliptic nutlets. Kükenthal (1936) placed
C. neocooperi
species in the very heterogenous
C.
sect.
Lancei
based on its rather large and dark glumes. However, blackish glumes are correlated with
Cyperus
species
growing at higher elevation and originated multiple times within the genus, also, glume size does not seem to be reliable for infrageneric classification (
Reynders 2013
).
