Drosera subhirtella

Drosera subhirtella is a scrambling or climbing plant up to 40 cm long. It develops some bracts at the lower part of the stem and it may develop tuber producing stolons from the leaf axils. The tubers are yellow. Both the stem and the sepals are glandular which distinguishes Drosera subhirtella from the other two yellow-flowered climbing species Drosera intricata and Drosera moorei. The seeds are relatively long (more than 2.5 mm).

You can find a full description of this species here: http://florabase.dec.wa.gov.au/nuytsia/search?authors=&title=drosera&abstract=&published_on=&volume=&part= (scroll down, pdf currently unfortunately not available): A. Lowrie, A taxonomic review of the yellow-flowered tuberous species of Drosera (Droseraceae) from south-west Western Australia, Nuytsia 13 (1): 7587 (1999)
The three species can be most easily differentiated once they flower:
D. moorei: stem and sepals glabrous
D. intricata: All plant parts (excluding the sepals) glabrous
D. subhirtella: All plant parts (excluding the lowermost section of stem, stamens, styles and petals) glandular
