Dactyloctenium ruderalis is closely allied to D. aristatumLink but differentiated as in table 1. and key to with its closely related species is as mentioned above. Various herbaria have been consulted in India and abroad to ascertain the identity of species by comparing the specimens. D. ruderalis and D. germinatumshare some characteristic features like height and rare occurrence of singe spike in the latter. Since, the former is non-stoloniferous and the letter is stoloniferous. The new species is reported from Jammu where D. aegyptium is frequently found. Of these two species the former is stoloniferous and prostrate and ascending and the letter is more closely allied D. aristatum. Both these species are rooting from the base of stem.
