Taxon concept:

 Key to the subspecies 
1Floral cushions not protruding, but with visible sparse, long red hairs which are mostly in a single row between flowers Rudimentary leaves 0.5–1 mm high, membranous, usually obtuse, together continuous around node and almost continuously free except fusion to face of internode at its midpoint. Flowers almost completely encircling node in early stage, separating as internode expands. Flowers chiefly spring. Parasitic on a wide range of trees in rainforest and wet sclerophyll forestsubsp. rubra
Floral cushions protruding in older, and longer than flowers in younger inflorescences, with a dense mass of white hairs; flower clusters separated by a distinct triangular area of internode surface. Rudimentary leaves distinct only around flower clusters, acute, tapering from 0.5 mm high at outer limit of floral cushion to 0.2 mm high at inner limit together extending across face of internode between flower clusters as a rim 0.2 mm wide and not spreading, which are distinct at all stages. Flowers throughout year. Parasitic mostly on Geijera parviflora.subsp. geijericola
