A detailed taxonomic account and karyological investigations on the species are not yet available. The taxonomy of Nogra dalzellii is reviewed here. Complete description and illustration are provided. The binomial Grona dalzellii Baker [(≡) Nogra dalzellii] is lectotypified. A diploid chromosome number of 2n = 22 and karyotype of Nogra dalzellii are reported here for the first time. The mean chromosome length is 2.55 ± 0.41 μm and the total chromosome length of the haploid genome 28.01 ± 0.41 μm. The shortest chromosome measures 1.83 ± 0.37 μm and the longest one 3.25 ± 0.57 μm.
