H. arenarium (L.) Moench, Meth. 575 (1794). Syn: Gnaphalium arenarium L., Sp. PL 854 (1753).   Plant grey-adpressed-tomentose, eglandular. Flowering stems 9-46 cm, arising from short stout branched caudices. Sterile shoots with prominently swollen leaf-bases. Basal leaves often crowded, linear-oblanceolate to spathulate, 7-60x1∙5-8 mm; cauline ones narrowing to linear above; sometimes with crisply undulate margin. Capitula numerous, subglobose. Phyllaries ± flat or cucullate, yellow (rarely straw-coloured) or apricot. All flowers hermaphrodite. Fl. 5-8. Dry calcareous or sandy soils; steppe, banks, 250-3200 m. 1. Phyllaries cucullate, apricot, yellow or straw-coloured subsp. rubicundum 1. Phyllaries flat, yellow    2. Leaves undulate; basal leaves 7-20 x 1∙5-4 mm subsp. erzincanicum    2. Leaves not undulate; basal leaves 10-50 x2-8 mm subsp. aucheri subsp. erzincanicum Davis & Kupicha in Notes R.B.G. Edinb. 33:240 (1974). Figure 5, p. 87.

The following are similar, but have stems c. 30 cm tall and sparser basal leaves; they approach subsp. rubicundum, but have flat, rather than cucullate, phyllaries: A4/5 Kastamonu: Giaurtchaidere, Sint. 1892:4504!

The Euro-Siberian subsp. arenarium occurs throughout W. and C. Europe and C. and S. Russia. It is distinguished from subsp. aucheri by the absence of sterile shoots with prominently swollen leaf-bases.
