27012013 BRS 444: 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

Thank you very much for drawing notice to this cyperus species as have been described in the Dave’s Garden –
http://davesgarden.com/guides/pf/go/2532/.
Search for the Cyperus alternifolius in The Plant List gives –
Search for the Cyperus involucratus in The Plant List gives –
GRIN has –
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..
