Living collections of this taxon is also under ex situ conservation outside the islands at the Field Gene Bank of Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Trivandrum, India. This is a 'narrow endemic' rarely found in the interior evergreen forests of this archipelago. The flowers are typical creamy yellowish with purple coloured interior.
