(b) Subsp. subcaulescens (L’Hér. ex DC.) Hayek , Prodr. FI. Penins. Balcan. 1: 572 (1925)

( G. subcaulescens L’Hér. ):

Leafsegments up to 5 mm; usually at least some of the sepals with plentiful long, white hairs; petals usually deep reddish-purple, but sometimes pale. S. & W. part o f Balkan peninsula; C. & S. Italy. Plants which resemble 3 in many features but differ in others have been described from calcareous mountains in several regions of Spain. They occur in disjunct populations, and it is difficult to give them satisfactory taxonomic treatment; they should probably be regarded as variants or subspecies of 3. G. subargenteum Lange in Willk. & Lange, Prodr. FI. Hisp. 3: 525 (1878), from the Cordillera Cantâbrica, has the leaves very densely appressed-pubescent (grey-green above, silvery beneath); sepals without long hairs; and petals deep purplish-pink. G. dolomiticum Rothm. , Bol. Soc. Esp. Hist. Nat. 34: 151 (1934), from N.W. Spain (S. of Ponferrada), is robust, with petioles up to 15 cm; leaves pale green beneath; stem sometimes branched and with cauline leaves near the base; sepals acute to acuminate, with long marginal hairs; and petals apparently fairly deep purple. G. cazorlense Heywood , Bull. Brit. Mus. (Bot.) 1: 112 (1954), from S.E. Spain (Sierra de Cazorla), is small and densely caespitose, with closely contiguous leaf-lobes bearing short, rounded segments; sepals small, acute or shortly mucronate; and petals 12 mm, white with violet veins.
