Drosera bulbosa was a common sight on the granite outcrops throughout my 2019 expedition to Western Australia. The species is highly variable in both color, ranging from bright yellow to deep purple, and leaf shape, which varied from rounded leaves to long, pointed ones. The species was present at almost every outcrop in the Wheatbelt and the Perth hills, occupying mossy patches on the rocks and the swampy drainage fields that extended around them. It can be readily distinguished from similar rosetted species by its raised central vein and generally elongated leaves.
