New Publication - Two new species of Annonaceae

Zacky Ezedin, former HUH Research Fellow and current Associate, has a new publication in Candollea highlighting some of the work he completed on the flora of Papua New Guinea while at the HUH. Ezedin uncovered two striking new plant species in the Annonaceae family, each breaking the usual “rules” of its group.

Abstract
Two new species of Annonaceae bearing unique or unusual morphologies are described and illustrated from Papua New Guinea. Goniothalamus metadoxus Ezedin, from the Papuan Peninsula, exhibits an extraordinary reduction of the outer petals resulting in an inverted floral morphology where the inner petals appear larger and more prominent. It is further distinguished by its long pedicels, inner petals bearing a densely sericeous indument giving a silvery-white sheen, and long apiculate staminal connectives that are pinkish-lavender in color. Uvaria chrysoflora Ezedin, from the Sepik River basin, is unique in bearing greenish-yellow flowers, making it the first non-red flowered species of its genus from Papuasia. It most closely resembles the widespread U. concava Teijsm. & Binn. and can be further distinguished from the latter by its smaller leaves and larger flowers.
