Abstract:
Freycinetia is a one genus under Pandanaceae family beside Pandanus, Sararanga, Martelidendron and Benstonea. The Genus has widely variation in New Guinea island that is suspected as a centre biodiversity of Freycinetia . Study about taxonomy, biodiversity and distribution of Papuan Freycinetia species have been doing from 2005 to 2018 using both morphological and molecular data. Result have shown that about a 100 more species of Freycinetia occur in west New Guinea. All species
have their own characters especially character diagnostic to recognize them. Stigma as a diagnostic character has vary and the variation not only include previous character state but also something new. Some species have their unique stigmaareola characters for example F. megaauriculata, F. imbristigma, F. pauciberria, F. desendata and F. broccoareola. Stigma characters and function of them in the speciation will be discuss more in this paper.
