Lycopodium deuterodensum Herter, Index Lycopod. 15 (1949) (L. densum Labill. nom. illeg. non Lam.) has been recorded from Norfolk Is., first by Bentham (Fl. Austral. 7: 676, 1878) and subsequently copied by other authors, but a search has failed to find any specimen upon which this record could be based, and the species has not been found since on the Island.
Terrestrial herbs, erect or creeping, often with rhizophores, usually much branched. Leaves numerous, small, 1-veined, with a small ligule, often of two kinds borne in two planes. Sporophylls in compact, terminal strobili (cones); sporangia axillary, producing 1–4 relatively large megaspores or very numerous, minute microspores; megasporangia and microsporangia usually in same spike.
A monogeneric family of perhaps 700 or more species, found mostly in the humid tropical or subtropical regions of the world, but with a few temperate species; 1 species naturalised on Norfolk Is.

Lycopodium kraussianum Kunze, Linnaea 18: 114 (1844).T: Natal, South Africa, C.F.F. von Krauss; iso: K. Named after the collector of the type specimen.
Trailing herb, 20–30 cm long, much branched, with a rhizophore at each branching. Leaves of two forms: lateral leaves crowded on terminal branches, lanceolate-oblong, 2–3 mm long, acute; median leaves appressed, lanceolate, 1.5–2 mm long, acuminate, slightly keeled. Cones, when produced, narrow, 5 mm long; sporophylls ovate, acuminate, keeled.
Occurs on Norfolk Is.
A garden escape, persisting as a weed in a few places.

Selaginella uliginosa (Labill.) Spring was recorded by G.Bentham (Fl. Austral. 7: 678, 1878) from Lord Howe Is., based on a collection by C.Moore. This has not been traced and it is believed that the specimen at Kew annotated in Baker's hand: 'Lord Howe's Island Hb. Macleay recd. 5/73' is mislabelled.
Terrestrial or epiphytic herbs; rhizome short, erect. Fronds solitary or few, simple or divided. Sporangia borne in a simple or branched spike which arises on or at the top of the common stipe of the lamina. Sporangia numerous, large, without an annulus, many-spored, in Ophioglossum ±sunk into the surrounding tissue.
A worldwide family of 4 genera and c. 55 species; 2 genera native to Lord Howe Is., 1 also native to Norfolk Is.

Sterile lamina simple, or the upper end sometimes once branched; venation reticulate
Sterile lamina compound; venation open and dichotomous
OphioglossumL. Sp. Pl. 2: 1062(1753) Gen. Pl. 5th edn, 484 (1754); from the Greek ophis (snake) and glossa (tongue), from Adder's Tongue, the folk-name in several languages

The description above is based on Hutton 578, cited above; with further collections the dimensions may be increased slightly. It appears to coincide with J.H.Wieffering's figure of O. reticulatum f. dilatatum (Miq.) Wieff. in Blumea 12: 325 (1964).

Terrestrial, erect herb 5–15 cm tall. Sterile lamina somewhat thick, narrowly to broadly elliptic, rarely somewhat lanceolate, (1–) 2–4 (–5) cm long, 0.6–2 (usually c. 1.2) cm broad, usually widest towards middle, basally acute to narrowly acute, venation ±obscure.

Lord Howe Is. Of scattered occurrence throughout the Island, but never common. Also known from all Australian States and New Zealand.
Variable in size, and to some extent in the shape of the sterile laminas, this species has been the cause of much taxonomic confusion and is sometimes included in O. lusitanicum by Australian authors (e.g. R.Chinnock in J.P.Jessop & H.R.Toelken, Fl. S. Australia 4th edn, 1: 84, 1986).

Sterile lamina 1–several, pendulous, strap-shaped, 30–100 cm long, 1–3 cm broad, gradually narrowed into an indefinite stipe, rounded, with apical part sometimes dichotomously forked; veins narrowly reticulate.

Lord Howe Is. Rare. Also known from Madagascar, Ceylon and Malesia, to Australia (Qld and northern N.S.W.), and to the south-western Pacific islands, but not on Norfolk Is. or New Zealand.
