Renner, Matt A. M., 2013, A new subspecies of Acrolejeunea arcuata, and notes on typification, synonymy, and distribution of other Australasian Lejeuneaceae, Phytotaxa 83 (1), pp. 39-53 : 50-51

Lejeunea tumida Mitt. in Hooker (1855: 157).

Eulejeunea tumida (Mitt.) Stephani (1915: 800) .

Type:— NEW ZEALAND. Auckland, Dr. Sinclair s.n. ex herb. Mitt. (lectotype fide Grolle (1982): NY, isolectotypes: MPN, WELT!) .

The name Lejeunea tumida has been misapplied to a range of Australian Lejeunea species , including L. cuspidistipula ( Stephani 1896: 88) Stephani ex Watts (1902: 493) , L. drummondii Taylor (1846: 400) , L. sinclairii Spruce non Mitt. auct. and L. sordida . The presence of L. tumida in Australia was considered dubious by Renner et al. (2010), but the species was not explicitly rejected because all material forming the basis of early records had not been investigated. Recent examination shows that early identifications of Australian material as Lejeunea tumida by Rodway and Stephani in the herbaria FH, BM and G are all referable to other species. Lejeunea tumida can therefore be rejected from the Australian flora with confidence. It, and all other members of the species group formerly included within it [ L. colensoana ( Stephani 1896: 132) Renner in Renner et al. (2010: 455), L. oracola Renner in Renner et al. (2010: 448), and L. rhigophila Renner in Renner et al. (2010: 453)] are endemic to the New Zealand Botanical Region.
