6a. Senecio scopolii subsp. scopolii

Arnica lanigera Tenore (1812 : XLIX), non Senecio lanigerus Burman (1768: 26) . TYPE: Italy, Basilicata, Potenza, Ruggio [Ruggia, 39º54'N 16º07'E], M. Tenore s.n. (lectotype, designated here, NAP image!; syntype, LE!, P-3688098 image!, P-3688124 image!).

Senecio doronicum var. latifolius Visiani (1847: 71) [ “latifolia ”]. Senecio doronicum f. latifolius (Visiani) Hayek (1931: 674) . TYPE: Croatia, in Biokovo, [43º20'N 17º03'E], R. Visiani s.n. (lectotype, designated here, PAD image!).

Senecio doronicum f. albanicus Kümmerle & Jávorka in Jávorka (1920 –1921: 28). TYPE: Albania, montes nivales Korab , [41º47'N 20º32'E], 24 July 1918, J.B. Kümmerle s.n. (lectotype, designated here, BP-410478 image!).

Senecio arachnoideus Sieber , nom. nud., in sched. ( McNeill et al. 2012, ICN Art. 38.1) (H-1442050!, LE!, PR-615648!, PR-270247!).

Stem leaved. Leaves lanceolate to oblanceolate, attenuate, usually thin and soft, light green, with arachnoid-floccose indumentum. Apex of the involucral bracts usually without a black spot. Chromosome number: 2 n =38–40 ( Cesca & Palermo 1981: 388, sub S. tenorei , see comments below). Figure 8C .

Iconography: — Tenore (1830, fig. 193-1); Reichenbach (1853, fig. 975-2); Hegi (1928: 753, fig. 459).

Distribution and habitat: — Albania, Bosnia-Herzegovina, Croatia, Greece, Italy, Macedonia *, Montenegro, Serbia *, Slovenia; montane and subalpine meadows, rocky slopes, edge of woods of Fagus sylvestris and Carpinus sp. , on calcareous soils; elevations of 330–2800 m ( Figure 10 ).

Phenology: —Flowering from April to July.

Discussion: —The specimen collected at Mount Korab ( Albania) by Kümmerle was described as S. doronicum f. albanicus . Its lanate involucre and floccose indumentum on the stem and leaves are remarkable, conferring an unusual whitish aspect.

We did not have a chance to study material of this taxon from Serbia and Macedonia, although we include them with an asterisk in the distribution according to Euro+Med PlantBase (2006+, http://ww2.bgbm.org/ EuroPlusMed/PTaxonDetailOccurrence.asp?NameId=7000832&PTRefFk=7000000, accessed 18 March 2014).

The chromosome number recorded by Cesca & Palermo (1981) under S. tenorei comes from Monte Pollino (Calabria, Italy); according to the present treatment, the populations from this region correspond to S. scopolii subsp. scopolii . Otherwise, the voucher material for the chromosome number (2 n =40) provided by Küpfer (1974) and Chichiriccò & Tammaro (1982) are from the Central Apennines, where the ranges of both subspecies overlap. Since we could not revise these vouchers, we prefer not to assign these counts to any subspecies.
