Thanks. I found the Robin White (Timber Press) book on Amazon: it looks
from the material made available that it doesn't go into infrageneric
classification.

The Timber Press is pretty serious, these days, and it might be in there.
The genus is not big and half a page would cover it, and it would definitely
not make it to the blurb text. Without looking at the book it is not
possible to tell, so I thought it worthwhile to mention it.

Since I last looked a new paper on Cistus has appeared - Guzman &
Vargas, Systematics, character evolution, and biogeography of Cistus L.
(Cistaceae) based on ITS, trnL-trnF, and matK sequences, Mol. Phylogen.
Evol. 37(3): 644-660 - but all that is readily available is the abstract

This kind of analysis often does not go into the taxonomics of things.
Still, it gives you an address to inquire at.
