[ Ilypopterygium. 
acuminate. Fruitstalk reddish, ± in. long. Capsule pendulous ; operculum 
beaked. Calyptra dimidiate. Inflorescence dioecious. — Hookeria rotulata. 
Smith in Linn. Trans, ix. 279 (not Leskea rotulata of Hedwig). 
Abundant throughout the islands, at the roots of trees, etc., Menzies, etc. (Tasmania, 
Australia.) 
5. H. discolor. Mitten, mss. Habit of H. novce- Zelan dice, but rather 
larger, not turning yellow when dry ; branches recurved at the apex. Leaves 
on the stem broadly obliquely-ovate, subcordate, acute, serrulate ; nerve 
vanishing at the middle, or the branches broader upwards, with longer nerve; 
dorsal leaves on the stem orbicular, acuminate with the short nerve, on the 
branches serrulate above with percurrent nerve ; pericliaetial small, ovate, 
acuminate. Fruitstalk red. Capsule ovoid, horizontal ; operculum with a su- 
bulate beak. Inflorescence dioecious. 
Northern Island: Auckland, Knight, Jupp ; Kiapara, Mossmann. 
6. H. glaucum, Sullivant, Musci of U. S. Expl. Exped. 26. — II. 
Smithiunum, fi. FI. N. Z. ii. 118. A very small species ; stems tufted, -j- in. 
high ; branches forming a nearly orbicular crown, pale glaucous yellow-green, 
decurved. Leaves closely imbricate, very deflexed, broadly ovate-acuminate 
or apiculate, obscurely serrulate ; nerve produced halfway or more ; dorsal 
large compared with others, orbicular, abruptly acuminate, with the nerve 
continuous. Fruitstalk stout, arcuate. Capsule ovoid, cernuous ; operculum 
with a slender beak, nearly as long as the capsule. 
Northern Island: common at the roots of trees, from the Bay of Islands, A. Cunning- 
ham, etc., southwards. 
7. K. tamariscinum, Sullivant, Musci of U. S. Expl. Exped. 26. — II. 
setigerum, Hook. f. and Wils. Fi. N. Z. ii. 118. Stems 2 in. high, branched 
as in II. rotulatum. Leaves yellow-green, rather glossy, mixed with small 
bristles, distichous, ovate-acuminate, spinulose-serrate ; nerve vanishing ; 
dorsal ovate, more acuminate, spinulose-ciliate. Fruitstalk very stout, \ in. 
high; purplish, suddenly deflexed at the top. Capsule ovoid, pendulous, 
pale, abrupt and tubercled at the base ; annulus distinct ; operculum yel- 
low, beaked, as long as the capsule. Calyptra not dimidiate. Inflorescence 
dioecious. — Hypnum setigerum , Palisot. Leskea tamariscina, Hedwig, Sp. 
Muse. t. 51 (not Hypnum tamarisci of Swartz); FI. Antarct. i. 136. 
Abundant throughout the islands, Cunningham, etc. Lord Auckland’s group, J. D. H. 
(barren). — Sullivant restores the name of tamariscinum to this plant, it being identical with 
Hedwig’ s figure and description of Leskea tamariscina. 
8. H. rotulatum, Hedwig (Leskea), not of FI. N. Z. ii. 118. Stem short, 
naked below, 2-pinnately branched in a radiating manner above, there orbicular. 
Leaves mixed with a few setae, dull green, not crowded, distichous, spreading, 
crisped or undulate when dry, orbicular-ovate ; margin thickened, slightly 
toothed at the apex ; nerve vanishing above halfway ; dorsal orbicular, 
apiculate ; nerve very short ; perichaetial ovate-lanceolate, concave, setulose 
on the back and apices, acuminate. Fruitstalk \ in. long. Capsule pendu- 
lous ; neck tubercled ; operculum beaked. Inflorescence monoecious. — 
Leskea, Hedwig, Sp. Muse. t. 51.
