Although intermediates between subsp.
filifolia and each of the other three subspecies, and between subsp.
schaeferi and subsp.
bodkinii are known, the subspecies are distinct even when growing at the same location.

Subsp.
bodkinii has broad synflorescences, and succulent leaves of up to 2 cm long that are set evenly along the stems, including the peduncle.

Subsp.
filifolia has long synflorescences, and slender, sometimes somewhat flattened leaves of up to 3 cm long.

Subsp.
schaeferi has broad synflorescences, and succulent leaves of up to 2 cm long, set in groups, with the lower part of the peduncle crowded with leaves and the upper part almost leafless.

Subsp.
schlechteri has broad synflorescences, and succulent leaves of up to 4 cm long.
