Specimen examined.

Nepal, Jhapa: Kachankawal Rural Municipality (RM), Baniyani, 26°26'15.94"N, 88°3'1.28"E, 71 m elev., 04 Dec 2020, S. Chaudhary 20120410 (KATH, TUCH).

Note.

The first author visited: Rupa Lake and other wetlands of Pokhara Valley, Central Nepal and Jhapa District, East Nepal; observing multiple specimens. Samples deposited at KATH (Central Nepal, S. Dahal 20074) and TUCH (Central Nepal, R.R. Kafle 7) were examined. Upon close inspection of the culm, glume and achene characters, the Central Nepal populations exactly match Actinoscirpus grossus var. grossus , while the East Nepal populations matched with that of Actinoscirpus grossus var. kysoor . Therefore, it can be concluded that the two varieties of Actinoscirpus grossus occur in Nepal.
