### Author
Röll, Julius (1846-1928), German (Sachsen-Weimar) bryologist; studied at Jena; Dr phil. 1873; teacher at Frankfurt a.M. 1874-1876; high school teacher at Darmstadt (Victoriaschule; teachers college) 1876-1911; professor's title 1909; collected in N. America 1888-1889; from 1914-1928 in retirement at Klösterlein bei Aue.
**Abbreviated name**: *Röll* \[standard form in IPNI: *Röll*\]
#### Herbarium and types
[[Collection WB|WB]] (fide IH 1 (ed. 7)); other material at [[Collection B|B]], [[Collection H|H]]-BR (musci), [[Collection PC|PC]], [[Collection PI|PI]], [[Collection S|S]].
#### Note
For a fundamental criticism of Röll's ideas and practices in the nomenclature of *Sphagnum* see C. Warnstorff, Verh. bot. Ver. Brandenburg 52: 22-38. 1911 (" sein oft rücksichtloses Vorgehen gegen andere, die seine Ansichten nicht zu teilen vermögen ..."). See e.g. Röll, *Zur Systematik der Torfmoose*, treated below; and Röll (typescript) Antrage betr. Aendrungen und Zusätze zu den internationalen botanischen Regeln in Bezug auf die Nomenclatur der Sphagna (11 p. typescript, n.v.). For a modern evaluation and summary see P. Isoviita (1966): it is proposed to reject the names of Röll's series because they do not apply to species.
