This species is a slender, succulent shrub. The leaves are small, slender (10–14 x 1–3mm), and often slightly wider than they are thick (i.e. slightly flattened). Each leaf has a pointed hook at its tip, that curves downwards. Like D. speciosum and D. pulchrum, it has smooth leaf-surfaces. The flowers can be bright yellow, orange, pink or red.
Drosanthemum lavisii can be distinguished by its recurved, hooked (uncinate) leaf-tips. This character, especially prominent in new leaves, and is also seen in D. edwardsiae and D. uniondalense.
It can also be distinguished by the rough base of its calyx, with 9 to 13 bladder cells along each ridge. This character is shared with D. boerhavii however.[1]
Drosanthemum lavisii is part of a group of similar Drosanthemum species, in subgenus "Speciosa". These nine species all have black filamentous staminodes in the centre of their flowers, they are all small, erect shrubs, and they all occur in the southern Cape, South Africa.
Other species of Drosanthemum subgenus Speciosa include: Drosanthemum bellum, Drosanthemum boerhavii, Drosanthemum edwardsiae, Drosanthemum hallii, Drosanthemum micans, Drosanthemum pulchrum, Drosanthemum speciosum, and Drosanthemum uniondalense.[2][3]
