Pindpinna

Pindpinna is a monotypic genus of flowering plants in the family Pindpinaceae, described from specimens collected in the Zest Highlands in the tropics. The genus comprises a single species, Pindpinna alba, distinguished by its white flowers and glossy leaves. It was described in 2023 by botanists studying montane flora of the region.

Pindpinna alba is an evergreen shrub growing 1–1.5 meters tall. The leaves are opposite, simple, 4–8 cm long, with a leathery texture and a glossy dark green blade. The inflorescence is a loose panicle carrying numerous small, white to cream flowers. Flowers are hermaphroditic; fruit is a dry capsule containing several tiny seeds.

Endemic to the Zest Highlands, Pindpinna alba occurs on rocky limestone slopes and talus at elevations around 900–1400 meters. The region experiences a misty, cool-dry season and a wet season, fostering well-drained soils favored by the species.

The genus name Pindpinna derives from the local dialect word pindpin meaning "rock leaf," and the species epithet alba refers to the color of the flowers. The taxonomic placement within angiosperms follows standard flowering-plant classifications, though molecular data remain limited.

Pollination is primarily by native bees, with limited wind contribution. Seed dispersal is via gravity and short-distance wind. In cultivation, it is valued as an ornamental plant in montane garden settings and is used in some traditional remedies in nearby communities.

With its restricted range, Pindpinna alba is potentially vulnerable to habitat disturbance and quarrying in its native region, though formal assessments have not been widely published.
