11. GYMNANTHE, Taylor. 
Stems prostrate or ascending, vaguely branched. Leaves succubous, dis- 
tichous. Stipules present or absent. Fruit terminal. Involucre a cylindri- 
cal pendulous tube, often fleshy and buried in the ground. Perianth 0 or 
adnate with the involucre. Capside on a slender fruitstalk ; elaters with 2 
spiral fibres. Antheridia free in the axils of the leaves. 
A small genus, with one species in the northern temperate zone and several in the 
southern. 
* Stipules present, very small. 
1. G. unguiculata, Mitten in FI. N. Z. ii. 144. t. 99. /. 6. Stems 
club-shaped, creeping, with numerous white rootlets, ascending, 1 in. long. 
Leaves pale green or tinged brown or purple, distichous, densely imbricate, 
connivent and appressed, suberect, suborbicular or obovate, upper large, ob- 
scurely 12-lobed, deeply spiuulose-dentate, with 8-10 large teeth ; dorsal 
lobe smaller. Stipules variable, 2-3-fid or palmate. 
Northern and Middle Islands : sulphur springs at Waimata, on a Hicranum, Co- 
lenso. A curious little plant ; the stems appear clavate from the closely imbricate leaves 
being progressively larger upwards. Fruit unknown, but plant very similar to G. Wilsoni 
of Britain. 
2. G. diplophylla, Mitten in Ft. Tasm. ii. 230. t. 179. /. 5. Stems 
short, 1 in. long, creeping. Leaves white, ^pellucid, membranous, cellular, 
closely imbricate, divaricating, conduplicate, unequally 2-lobed, upper lobe 
smaller, stipuliform, toothed and ciliate. Stipules 2-fid ; segments toothed 
and ciliate. Perianth terminal, short, cylindric, purple. — J. diplophylta , FI.

** Stipules 0. 
f Leaves quite entire. 
3. G. Drummondii, Mitten in FI. N. Z. ii. 144. t. 99./. 8. Stems f 
in. long, stout, creeping, rooting at the tips. Leaves greenish-brown, imbri- 
cate, spreading, flat, upper larger, ovate, obtuse, quite entire ; dorsal margin 
subrecurved. Involucre as long as the plant, clavate, with scattered rootlets.

squamata, Tayl. in Hook. Lond. Journ. Bot. 1846, p. 413 ; Syn. Hep. 789. 
Northern Island : forests of Titiokura, Colenso. (Australia and Tasmania.) 
ft Leaves 2-cuspidate, otherwise quite entire. 
4. G. lophocoleoides, Mitten in FI. N. Z. ii. 144. t. 99./. 7. Stem 
1^ in. long, creeping, covered with rootlets below. Leaves pale yellow-green, 
distichous, spreading, flat, obovate-quadrate or cuneate, 2-lobed at the apex ; 
lobes subulate. Involucre unknown. 
Northern Island : Tararua mountains, creeping amongst Plagiochila falcata, Colenso. 
This quite resembles a Lophocolea in habit, and its genus must be very doubtful in the 
absence of fructification. 
ttt Leaves more or less toothed. 
5. G. setulosa, Mitten in FI. N. Z. ii. 144. t. 99. /. 5. Stem 1 in.
