Polyscias flynnii (known by the common names Flynn's ʻOhe and ʻOheʻohe) is a plant species endemic to the island of Kauai in Hawaii. It is rare, found only in one population covering about 1 km2 in the Kalalau Valley. It is regarded as threatened.[1] It is threatened by feral goats and non-native plant species in its habitat. It was federally listed as an endangered species of the United States in 2010.[2]
This plant was first discovered in 1988 and described to science as a new species in 2000.[3] There are only five individuals known to exist.[4]
Polyscias flynnii is a tree up to 9 m tall. Leaves are pinnately compound, up to 60 cm long, with reddish-brown hairs on the underside but not on the upper side. Inflorescence is a panicle or umbel hanging from the axils of the leaves, with 10-15 flowers. Flowers are yellow-green, some hermaphroditic (both male and female) but others on the same plant staminate (male only).[3] [5]
