Richea
Xcurtisiae is a hybrid between Richea scoparia and R.
pandanifolia. These hybrids are relatively common wherever both
species occur (especially after disturbance).
They are similar to R. alpina
in leaf and inflorescence form. However, they usually have an
erect habit, whereas R. alpina is very short and unbranched
or is broadly spreading. R. alpina is restricted to the high
mountains of the deep south-west (Frankland, Wilmot, Western
and Eastern Arthur Ranges, Mt Bobs), whereas Richea Xcurtisiae occurs
in the west and central mountains, especially after disturbance.
