( C. supina Jordan ):

Like subsp. (b) but stems short; leaves greyish-tomentose or -lanate. S. France.

C. pectinata var. thuretii Briq. & Cavillier , from S.E. France (N. of Nice), is known only from the original gathering; it is like subsp. (a) but the leaves are green and glabrous, the upper narrowed at the base. It may possibly represent another subspecies.
