The long sharp, triangular leaves are dark brownish green with white linear spots and cartilaginous margins.

Tall, very thin multi-branched inflorescences appear from January to March, with small sparse pale pink and sometimes bluish flowers.

Recent phylogenetic studies have shown these three species to constitute an entirely separate genus, what was published under the name Gonialoe.

[4] 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.

[5] Gonialoe dinteri is found in fragmented populations across a large, arid portion of Namibia, around the edges of the Namib Desert, into extreme southern Angola.
