CATE Araceae, 17 Dec 2011.

In its growth form, with long pendent stems with abbreviated flowering shoots arising in the leaf axils, Rhaphidophora stolleana resembles R. brevispathacea. The inflorescences are, however, quite different, with the spathe ovoid-cylindrical, 3-4 cm long, spadix slender cylindrical, 2.9-3.4 cm long in R. brevispathacea v. the spathe c. 10.2 cm long, spadix c. 8 cm long in R. stolleana. To date, R. stolleana is known only from East Sepik and R. brevispathacea only from Mimika/Digul Province.
