Lejeunea hodgsoniana  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. The species is endemic to New Zealand.
