The protologue of Fimbristylis salbundia [≡ Trichelostylis salbundia ] was based on two collections of Wallich, i.e. Wallich 3499 and 3526 from ‘Nepalia’ and ‘Silhet’, respectively ( Wallich 1828; Nees 1834). All collections representing 3499 were later annotated as F. quinquangularis (Vahl) Kunth., except 3499c at B, which was F. salbundia (Nees) Kunth ( Clarke 1907). The collection 3499c at B was destroyed in 1943, during the Second World War ( Halder and Dey 2016). Subsequently, the occurrence of F. salbundia was not reported in the published works ( Koyama 1978; Press et al. 2000; Rajbhandari and Rai 2017; Shrestha et al. 2018; POWO 2019; Govaerts et al. 2021). The rediscovery of F. salbundia after 200 years confirms the occurrence of this taxon in Nepal.

Fimbristylis salbundia is very similar to F. quinquangularis , but can be distinguished, based on the nature of its leaf sheaths and achene character. Fimbristylis salbundia is characterised by the presence of bladeless sheaths and sparsely verruculose achene, surface pitted with more than nine vertical rows of transversely oblong epidermal cells. However, Fimbristylis quinquangularis has leaf sheaths with blades and densely verruculose achene with up to six vertical rows of transversely linear-oblong epidermal cells.
