[Botany • 2017] Paphiopedilum lunatum & P. bungebelangi • Two New Species of Paphiopedilum (Orchidaceae: Cypripedioideae) Section Barbata from Sumatra, Indonesia

Paphiopedilum lunatum  Metusala

Two new species of Paphiopedilum from Sumatra, Indonesia, are described and illustrated. These two species belong in Paphiopedilum section Barbata and are so far known only from Aceh Province in the north of Sumatra.

Paphiopedilum lunatum Metusala, sp. nov. section Barbata

Etymology. From the Latin word lunatus, meaning bent like a crescent moon, in reference to the obviously crescent-shaped staminode of this species. 

Distribution. Indonesia, Sumatra, Aceh Province, Central Aceh Regency.

Habitat and ecology. Growing under shade as a terrestrial plant with roots in thick leaf litter or sphagnum moss. Its natural habitat ranges from open, flat areas dominated by forked fern (Dicranopteris sp.), low shrubs and grasses to slightly open forest on sloping hills dominated by rattan species, at 1300–1600 m altitude. 


Paphiopedilum bungebelangi Metusala, sp. nov. section Barbata

Etymology. The specific name is an adjective derived from the Gayo language (the Gayo people live in the highlands of Central Aceh), ‘bunge’ meaning flower and ‘belangi’ meaning beautiful, referring to the beautiful flower of this species.

 Distribution. Indonesia, Sumatra, Aceh Province, Central Aceh Regency. 

Habitat and ecology. Growing as a terrestrial plant with roots in thick leaf litter or sphagnum moss on sloping limestone hills from 1550–1650 m altitude. Plants were found growing in deep, shady forest with relatively low light intensity.
