The genus Shivparvatia Pusalkar & D.K. Singh was described in 2015 and the specimen J.D. Hooker 11 deposited in K (K000742193) was designated as the lectotype of its type species S. glanduligera (Edgew.) Pusalkar & D.K. Singh (≡ Arenaria glanduligera Edgew.). Nevertheless, J.D. Hooker 11 (K000742193) is actually the type of S. ciliolata (Edgew.) Pusalkar & D.K. Singh (≡ Arenaria ciliolata Edgew.). Thus the lectotypification of S. glanduligera was problematic and a re-lectotypification for this species is needed. One of the syntypes of S. glanduligera collected from Kashmir (H. Falconer s.n., K000742189) is selected here as its lectotype. Morphologically, S. ciliolata and S. glanduligera can be easily distinguished from each other by their different morphology of indumentum, disc gland and sepals, as well as the color of petals.
Arenaria, nomenclature, taxonomy
The genus Arenaria L. s.l. includes over 300 species of herbs widely distributed from Northern Temperate to arctic regions (

Morphologically, S. glanduligera can be easily distinguished from S. ciliolata by its glandular pubescence, prominent disc gland, not pure white and usually violet petals, and scarious sepal margin. In contrast, the latter is characterized by its ciliate pubescence, small disc gland, entirely pure white petals, and thickened sepal margin (
