Narrowly oblanceolate petioles emerging from the center of the rosette are typically 1.5–2.2 mm wide at their widest.

Red carnivorous leaves at the end of the petioles are small at 2–3 mm in diameter and elliptic to broadly ovate.

[1] Drosera kenneallyi is found in sandy loam soils on the margins of the Airfield Swamp.

In 1993, Allen Lowrie traveled to the Kimberley with the Landscope expedition and collected this species, introducing it into cultivation.

Drosera kenneallyi can be distinguished from D. falconeri by its noticeably smaller leaves and shorter inflorescence, but the two species share many characteristics.
