While this species looks rather similar to its two sister species, it can be distinguished from "Gonialoe sladeniana" by its longer leaves which curve downwards, and it can be distinguished from "Gonialoe variegata" by its large size, taller thinner sparser inflorescence, and the spots on its leaves being more linear, almost to the point of being stripes. The bracts of "G.dinteri" are 3 nerved, unlike its sister species which are 1 nerved. "G.dinteri" also has an unusually large root stock; its roots form a far larger percentage of its body weight than all the rest of the plant put together.
