Senecio paludosus var. leucophyllus (Candolle) Láng , nom. nud., in sched. ( McNeill et al. 2012, ICN Art. 38.1) (L-212592!, LE!).

Stem ± arachnoid, sometimes lanate in the upper half and glabrescent in the lower half. Cauline leaves weakly arachnoid to floccose above, ± tomentose-lanate beneath. Involucral bracts sparsely arachnoid to lanate. Achenes with scattered trichomes on the upper half, rarely almost glabrous. Chromosome number: 2 n =40 ( Váchová 1974: 18, sub S. paludosus, Letz et al. 1999: 47 , sub S. paludosus var. tomentosus ).

Iconography: — Gmelin (1770 –1774: fig. 15-1, as S. lanatus ); Reichenbach (1853: fig. 974-2, sub S. paludosus var. tomentosus ); Roldugin (1966: 155, fig. 17-4, sub S. tataricus ); Konechnaya (1994: 61, pl. 5, fig. 3, sub S. tataricus ); Hodálová (2003: 76, fig. 2C); Marhold et al. (2003: 374, fig. 3).

Distribution and habitat: — Belarus, Czech Republic, Germany, Hungary, Kazakhstan, Romania *, Russia, Slovakia?, Ukraine; marshes, banks of the rivers, edge of lakes, damp places, on silts, slimes, mud; elevations of 10–90 m ( Figure 15 ).

Phenology: — Flowering from June to September.

Discussion: — This taxon also presents variability in the indumentum of its leaves, i.e., the populations from central Europe are completely lanate beneath, while those from Russia are usually floccose. These specimens might be confused with those forms of S. paludosus subsp. paludosus that display floccose leaves beneath, but for the broader leaves (1–4.4 cm) and the achenes with only trichomes on the upper part that help to distinguish S. paludosus subsp. lanatus .

Marhold et al. (2003) lectotypified S. sadleri with a Sadler’s collection, however the original handwriting does not seem to belong to Sadler, nor the posterior annotation in red ink. Taking into account that Sadler acknowledged Láng in the original description, both handwritings could have been made by Láng. Another specimen from

On the other hand, the Láng’s collection from Tibiscum (Theiss in German) identified as “ S. paludosus var. leucophyllus DC. ” is not considered original material. We located duplicates at L and LE.

Regarding the lectotype of S. riparius , the curator of PR, O. Šída, kindly informed us that till now the voucher is oddly not located. Nonetheless, we found one isolectotype at JE that corresponds to S. paludosus subsp. lanatus . Based on the available original material, and despite the fact that this name was usually subordinated to subsp. paludosus , we consider more appropriate to include the name S. riparius as a synonym of S. paludosus subsp. lanatus . Moreover, we question that the mentioned type material designated by Marhold et al. (2003) corresponds to the original material. According to the label information of the isolectotype “a me anno 1819 in agro halensi detectus & in Sched. Cr. 482 descriptus”, it likely seems that the specimen was collected after the publication of the name S. riparius , and therefore, it could not be designated as lectotype.

According to Euro+Med PlantBase (2006+, http://ww2.bgbm.org/EuroPlusMed/PTaxonDetailOccurrence.asp?NameId=7000832&PTRefFk=7000000, accessed 18 March 2014), this taxon grows in Romania and its presence in Slovakia is questionable. We have not studied material from these regions, thus, Romania appear in the distribution with an asterisk and Slovakia with a question mark. Concerning the populations from western Siberia, we revised only one collection from Tomsk Oblast, although Wiebe (1997) also reported this taxon from Khanty- Mansi Autonomous Okrug, Tyumen Oblast, and Omsk Oblast.
