Arecaceae, Araceae, Zingiberaceae Fortnight 1-14 Aug 2014: Spathiphyllum sp. for ID from Uttarakhand_DSR_33 : 4 posts by 3 authors. Attachments (2). This Spathiphyllum sp is commonly planted as ornamental in Pantnagar. Please suggest correct ID. Spathiphyllum- species in India & eFIoraofindia with details & some keys I have very doubt about how scientific it would be if we do not have KEY as well as we do not know the names of various cultivars. Yet, as I searched for long acuminate leaves + short spadix I came across one wild species - http://biogeodb.stri.si.edu/biodiversity/species/17922/. The page gave me clue of two ornametal 1) S. floribundum and 2) S. patinii , both can be found at - http://www.biolib.cz/en/taxonimages/id62943/?type=1. Shorter spadix, acuminate leaves with distant nerves take me to Spathiphyllum floribundum (Linden & André) N. E. Br. I won't be surprised if I am wrong.
