Drosera porrecta

Erect plants with 1-3 basal rosettes. Non-flowering plants produce a single, unbranched stem up to 45 cm high with the leaves attached in whorls. Flowering specimens are usually branched above the uppermost basal rosette and much smaller (about 15 cm without inflorescence). A main inflorescence will arise from the from the uppermost basal rosette and smaller inflorescence may appear from any whorl of leaves.
The tuber is orange.

This species can be differentiated from other species in the complex as non-flowering specimens have a single stem bearing whorls of leaves along the the length. The branching in flowering specimens always occurs above the ground level whereas in D. stolonifera the branching occurs at ground level.
