Drosera neesii is an erect tuberous species endemic to coastal WA. Along with Drosera suphurea, the species is the only single-stemmed erect sundews in their range to bear crescent shaped leaves. There appears to be different forms of the plants; I observed them growing in the Perth Hills off the Brookton Highway, where they grew in wet seepages in clearings at the edge of Jarrah forest. The plants here were thin stemmed and orange in colouration.

Drosera neesii is readily distinguishable from D. sulphurea by the colour of its flower. D. neesii has a pink bloom whereas those of D. sulphurea are yellow. Without blooms, these two species are hard to distinguish.
