Its closest relative, D. ,?eesii,also occurs in thisregion but has a much greater range extendingeast to Cape Arid andnorth to Kalbarri.Specimens ofD.neesii occuning intheHill River- Mingenew-Kalbariregion areknown as subsp.roredlis N.G. Marchant.Otherthan having awhite tuber,D. neesiisubsp. borealis barely differs from D. neesii subsp. neesli. While the status ofD. neerii subsp.borealls requires further study, D. sulphureashows so many morphological differences from D. neesiilhat it is undoubtedlya distinctspecies. Droserasulphureahas a yellowor yellow-blushedpink tuber,stems 40-60 cm tall, yellow petals, sparselyglandular ovary, yellowish green styles c. 4.5 mm long,each divided into manybranching filiform segmentswith theapex ofeach segmentfurtherdivided into 3 shortsegments, and yellowish- greenstigmas terminating the ultimate segments. In contmst,D. neesiihas a darkmaroon or white tuber,stems 15-40 cm tall, pink petals,glabrous ovary, white styles c. 2 mm long,each divided into anumberofbranchingterete segments, andreddish-pink stigmas forming a slightly swollen emarginate projectionat the apexof eachsegment. The Drosera subhirtel/c complex Eachof thespecies belonging to theDrosera subhirtella complex can be identifiedby its unique seedmorphology. There are also significant differences within thegroup in themorphology of their vegetativeand floral organs.Many of thedistinguishing characters of the four speciesare given in Tablel.
