Lejeunea hodgsoniana Grolle ex R. J. Lewington, Bever. & M. A. M. Renner

" Lejeunea hodgsoniana is known from a number of locations in New Zealand ranging from latitude 29°14'39""S in the Kermadec Islands to latitude 44°20'S on Pitt Island in the Chatham Islands. In the northern half of the North Island, it is recorded from off-shore islands on the eastern coast from Poor Knights Island, south through the islands of the outer and inner Hauraki Gulf including the Mokohinau Islands, Hen and Chicken Group, Little Barrier Island and The Noises, and from the Mercury Islands Group and Mayor Island east of the Coromandel Peninsula. There are also a small number of northern mainland collections from North Cape south to Port Waikato and Hamilton. In the southern North Island, locations are mainly coastal in the vicinity of Wellington, including on Mana Island. On the South Island it is known from a single collection from the base of Farewell Spit. Elevation is generally less than 100 m with the altitudinal range from 1m to about 520 m, the latter in the Kermadec Islands. Four of the collections are from shaded stream bed rock, serpentinite at North Cape, basalt or basaltic andesite elsewhere. In most of its locations, however, Lejeunea hodgsoniana has been corticolous in coastal forest or scrub. Species of Melicytus, Melicytus aff. ramiflorus in the Kermadecs, Melicytus chathamicus in the Chatham Islands, and Melicytus ramiflorus elsewhere are the most frequently cited phorophytes or associates. Other cited phorophytes are: Acacia dealbata, Agathis australis, Beilschmiedia tarairi, Brachyglottis repanda, Coprosma macrocarpa, Coprosma repens, Cordyline obtecta, Geniostoma ligustrifolium, Hoheria populnea, Kunzea spp., Meryta sinclairii, Metrosideros excelsa, Metrosideros kermadecensis, Myrsine divaricate, Olearia traversiorum, Pittosporum umbellatum, Rhopalostylis sapida, Streblus banksii, Vitex lucens, and apple tree (Malus x domestica). Bryophyte associates have included Archilejeunea olivacea, Codonoblepharon minutus, Cololejeunea minutissima, Fabronia australis, Racopilum sp., Frullania monocera, Frullania patula, Frullania pentapleura, Frullania rostellata. Lejeunea colensoana, Lejeunea helmsiana, Lejeunea oracola, Lejeunea primordialis, Lepidolaena taylorii, Lopholejeunea colensoi, Metalejeunea cucullata, Metzgeria furcata, Neckera hymenodonta, Rhynchostegium muriculatum, Siphonolejeunea nudipes, Syntrichia papillosa, Tetraphidopsis pusilla and Thuidium sparsum.

Lejeunea hodgsoniana is a species of liverwort named in honour of Eliza Amy Hodgson. The often extensive mats formed by L. lamacerina are composed of small (shoots up to 2 cm long and 0.5–1.5 mm wide), delicate, pale green shoots. The lobules are smaller than the broadly rounded main leaf lobes. The underleaves are rather small and distant. Often fertile, with small, 5-keeled perianths. L. cavifolia (p. 221) has relatively larger, more overlapping underleaves and relatively smaller lobules. L. patens (p. 223) has a large, inflated lobule, which makes an acute angle with the leaf lobe. L. holtii (L. eckloniana) (Paton, p. 497) is a rare plant of south-west Ireland, and has distinctly elliptical leaves, with rather small underleaves and even smaller lobules. L. mandonii (Paton, p. 500) is also very rare in oceanic districts; it is as tiny as Harpalejeunea molleri (p. 219), but has slightly elongated, rounded leaf lobes and a very distinctive, smoothly rounded perianth that differs from the 5-angled perianths of most related species. Aphanolejeunea (p. 227), Microlejeunea (p. 220), Drepanolejeunea (p. 218), etc. – are usually much smaller, with differently shaped leaves, often longer and thinner or pointed. Especially characteristic of rock faces by streams in humid valleys, and often covering extensive areas. It is far less frequent on crags or on trees in the uplands.
