Syzygiella contigua

The original material ( Nova Granada, Lindig) of Jungermannia contigua Gottsche (1864: 118) , nom. illeg., non Jungermannia contigua Nees (1833: 360) , was housed in B and destroyed during World War II. We were not able to locate any duplicate of this collection. Stephani (1902a) replaced the name Jungermannia contigua Gottsche with Syzygiella contigua Stephani (1902a: 470) and cited the above Lindig specimen from Nova Granada as well as material from Brazil collected by Ule. Only the latter collection is available from several herbaria; Munich material of this collection from the Stephani herbarium was already cited by the monographer of the genus, Inoue (1966: 210). We designate this specimen as neotype of Syzygiella contigua . The neotype agrees perfectly with the description and type material of Syzygiella integerrima Stephani (1917: 117) and the latter is therefore placed in the synonymy of Syzygiella contigua .

The type collection of Syzygiella virescens Stephani (1902a: 469) from Brazil (leg. Puiggari) was not found in any herbarium (incl. BM, G, W) and is probably lost or destroyed. Thus, a neotype is here designated from additional Brazilian collections in the Stephani herbarium ( G), which Stephani also assigned to S. virescens . Both Brazilian specimens in G agree well with the original description. Inoue (1966: 210) already indicated that Syzygiella virescens “seems to be very similar to Syzygiella integerrima ”. We agree with this statement and place Syzygiella virescens in the synonymy of Syzygiella contigua (= Syzygiella integerrima , see above).
