The flower smells like fruits of bananas. Genus of Diptera... It grows in University Botanical Garden's Victoria-Warmhouse in Basel/Swizzera in a "mangrove-swamp"-like warmwater basin, living together with great big Victoria-plants.

This is a very large growing tropical aquatic aroid from Indonesia and Viet Nam. It is mat forming and can be grown as a true aquatic or in a bog. NOT SUITABLE for long term container growing. This plant has large very sharp spines that can be very dangerous. It is best placed where it will grow forever and left alone. It gets quite large with time, mine have trunks that measure 10-12+ inches in diameter. I have trialed it outdoors here for hardiness and it has successfully survived temperatures into the low 20's for short periods if grown as an aquatic. It loses some of its foliage but regrows almost immediately in very early Spring. The bloom is hard to photograph but extremely impressive in person
