Callmander, M.W., R. Razakamalala, I. Luino, R.L. Andriamarisoa & S. BUERKI (2020). Novelties from the Northern Mountains Complex of Madagascar V: A new threatened Pandanus (Pandanaceae) from the Kalobinono massif. Candollea 75: 99–105. In English, English and French abstracts.

A new species of Pandanus Parkinson (Pandanaceae) endemic to Madagascar is described as Pandanus kalobinonensis Callm., Razakamal. & Luino and illustrations are provided. The new species is restricted to the north-western lowland moist evergreen forests of the Kalobinono massif. Pandanus kalobinonensis can easily be morphologically distinguished from other members of the genus by its small solitary globose syncarp borne on a short peduncle, monocarpellate drupes, and single spiniform stigma with an adaxial stigmatic groove. Despite the occurrence of both collections within limits of the newly designated Galoko-Kalobonino Protected Area, the new species is preliminary assessed as “Endangered” [EN] using the IUCN Red List Criteria.
