Viola utchinensis |
Viola utchinensis (オキナワスミレ, Okinawa sumire) is a species of flowering plant in the family Violaceae.
The species was first described by Japanese botanist Gen-ichi Koidzumi in 1938. [2] The specific epithet relates to the type locality ( Manzamo in the village of Onna) on Okinawa Island ( Uchinā in Okinawan). [2]
Viola utchinensis is an evergreen with ovate leaves and pale purple to purplish-white flowers. [3] [4] Flowers bloom from February to April. [5]
Viola utchinensis is endemic to Okinawa Island in the Ryūkyū Islands of Japan. [2] [6]
This species can be found in crevices of raised coral reef and coastal cliffs. It grows in elevated habitat in full sun. [5]
Viola utchinensis is classed as Critically Endangered on the IUCN Red List and Endangered on the Ministry of the Environment Red List and has been designated a National Endangered Species under the 1992 Act on Conservation of Endangered Species of Wild Fauna and Flora. [1] [7] [8] In 2015 the population was estimated to be between 100 - 200 mature individuals. [5]
V. utchinensis is threatened primarily by the illegal collection of specimens for cultivation. This is believed to be the biggest threat for the species. [5] The species is attractive therefore is dug up to be used as rare ornamental plant.
