Pl. find the attached file contain photo for id. confirmation.
Location: Lalbag, Bangalore
Date: Dec. 2012
habitat: garden
Habit: grass like?


looks like Umbrella palmCyperus alternifolius
it popps up in disturbed land near water boies and high rain areas in the north eastern India including West Bengal…
the fan/umbrella shaped is very popular with flower arranging ladies esp for ikebana…
lots of seeds are produced, self seeds


It looks like the same as in /species/a—l/cl/cyperaceae/cyperus/cyperus-alternifolius. I saw this plant in Alipore Hort., later i also noticed it growing in the wild, beside a residential house.


Please also see Cyperus involucratus at – http://davesgarden.com/guides/pf/showimage/218974/#b.
FoC informs while Cyperus alternifolius is naturalized in many tropical areas Cyperus involucratus is widely cultivated.

both names are synonyms I think…?
on dave’s garden page at this page its listed as such… I quote…

Family: Cyperaceae (sy-peer-AY-see-ee) (Info)
Genus: Cyperus (sy-PEER-us) (Info)
Species: involucratus (in-vol-yoo-KRAY-tus) (Info)

Synonym:Cyperus alternifolius
Synonym:Cyperus alternifolius subsp. flabelliformis
Synonym:Cyperus flabelliformis

Thank you very much for drawing notice to this cyperus species as have been described in the Dave’s Garden –

Search for the Cyperus alternifolius in The Plant List gives –
Search for the Cyperus involucratus in The Plant List gives –

Two more sites –

So, i am totally confused.


Yes, Sir, I think it is, more precisely perhaps Cyperus alternifolius subsp. flabelliformis Kük., for its flexuose drooping involucral bracts, as in the KEY in FoC (Cyperus involucratus Rottb.) or illustration in FoP..

Bangalore – 05/0/14 – afternoon. Is this umbrella grass? Would appreciate Common & Bot. ID.

This is Umbrella papyrus/ Umbrella sedge wrongly also known as Umbrella palm/Umbrella grass.
This is not a grass or palm, but a sedge (Cyperaceae)
