Stigmatodactylus antennatus is a species of flowering plant in the family Orchidaceae. It is endemic to the Arfak Mountains of West Papua, Indonesia.[1]
Description
Stigmatodactylus antennatus is a small terrestrial orchid with a tuberous habit and a single leaf. The inflorescence bears 3–6 flowers with narrow, star-like sepals and petals.
The species is distinguished by its labellar callus bearing two long, slender, antenna-like appendages, along with a pair of triangular wings at the apex of the callus.[1]
Taxonomy
The species was formally described in 2026 by André Schuiteman, Reza Saputra, and Jimmy F. Wanma based on material collected in the Arfak Mountains.[1]
Distribution and habitat
This species is known only from the Arfak Mountains on the Bird’s Head Peninsula of West Papua, Indonesia, where it grows terrestrially in montane forest among moss and leaf litter at elevations of approximately 1,200–1,250 m (3,940–4,100 ft).[1]
Phenology
It flowers from October to November.[1]
Etymology
The specific epithet antennatus refers to the distinctive antenna-like appendages on the labellar callus.[1]
