Abstract
A new species, Miliusa lanceolata Chaowasku & Kesler (Annonaceae), is described and illustrated. It has been so far recorded from the D’Entrecasteaux Islands (Goodenough and Normanby Islands) and Louisiade Archipelago (Sudest Island), southeast off Papua New Guinea and is characterized by densely hairy young twigs, lanceolate leaves, and supra-axillary flowers with long pedicels. The relationship with similar species in the genus is also discussed and a key to the species of Miliusa in New Guinea is provided.
Highlights
The genus Miliusa Lesch. ex A.DC. (Annonaceae) possesses about 50 species distributed from India to Australia
Two subgroups can be recognized within the rest of Miliusa concerning the flower position and the base of the inner petals
In the course of studying the systematics of Miliusa we found some distinct specimens collected from Papua New Guinea that appear to be an undescribed species
