Pyrrosia sarthalensis

A felt fern described in 2021 from Jammu and Kashmir in the West Himalaya, known from very few collections. Like its relatives it is a creeping, leathery-fronded epiphyte or rock dweller of temperate Himalayan forest, so grow it cool, bright and well drained with a dry-tolerant winter.

Where it grows wild

Almost nothing is published beyond the description; Himalayan Pyrrosia typically creep over mossy tree trunks and shaded rocks in oak and mixed temperate forest.

Likely mid-montane temperate forest (roughly 1,500–2,800 m), inferred from the genus in the West Himalaya; the 3,932 m measured site is a regional centroid, not a collection site.
