The new generic name Torrentaria, a nomenclatural consequence of the legitimacy of Platyhypnum and the illegitimacy of Platyhypnidium (Bryophyta)

Ochyra, Ryszard

Abstract

Platyhypnum Loeske of 1911 is a legitimate generic name which cannot be considered as a homonym of Platy-hypnum Hampe of 1877. Platyhypnum is lectotypified with P. dilatatum (Wilson ex Schimp.) Loeske and this makes is the oldest candidate for a name of the segregate encompassing the broad-leaved species of the traditionally conceived genus Hygrohypnum Lindb. Platyhypnum consists of nine species and seven following new combinations are necessary: P. alpestre (Hedw.) Ochyra, comb. nov., P. bestii (Renauld & Bryhn) Ochyra, comb. nov., P. cochlearifolium (De Not.) Ochyra, comb. nov., P. duriusculum (De Not.) Ochyra, comb. nov., P. montanum (Lindb.) Ochyra, comb. nov., P. norvegicum (Schimp.) Ochyra, comb. nov., P. smithii (Sw.) Ochyra, comb. nov., and P. tsuruzigamicum (Cardot) Ochyra, comb. nov. Platyhypnidium M. Fleisch. of 1923 is an illegitimate name including the lectotype of an earlier generic name (Platyhypnum) and the new generic name Torrentaria Ochyra is proposed to replace it with T. riparioides (Hedw.) Ochyra, comb. nov., as its generitype. The following new combinations are proposed under this generic name: Torrentaria afrorusciformis (Broth.) Ochyra, comb. nov., T. aquatica (A. Jaeger) Ochyra, comb. nov., T. brotheri (Paris) Ochyra, comb. nov., T. fuegiana (Cardot) Ochyra, comb. nov., T. grolleana (Ochyra & Bednarek-Ochyra) Ochyra, comb. nov., T. hedbergii (P. de la Varde) Ochyra, comb. nov., T. intermedia (Herzog) Ochyra, comb. nov., T. lusitanica (Schimp.) Ochyra, comb. nov., T. macowaniana (Paris) Ochyra, comb. nov., T. mutata (Ochyra & Vanderpoorten) Ochyra, comb. nov., T. obscura (Besch.) Ochyra, comb. nov., T. peruviensis (R. S. Williams) Ochyra, comb. nov., T. subrusciformis (Müll. Hal.) Ochyra, comb. nov., and T. torrenticola (Ochyra, Schmidt & Bültman) Ochyra, comb. nov.
