Theca suberecta, curvata, brunnea, siccitate infra orem contracta, demum. obscure striata. Dentes suberecti, incurvi, 
rubri. Operculum capsulam sequans, rostro gracili, curvato. 
The above description has been drawn up from original specimens, gathered by Mr. Menzies (during Vancouver’s 
Voyage) in Dusky Bay, New Zealand. This plant differs from D. fasciatum, Hedw. (Sp. Muse. p. 127. t. 28.), in the 
longer, more setaceous, nerved leaves, solitary seta, and oblong theca. Two closely allied forms occur in Herb. Hook., 
one having longer stems and more rigid, lurid green leaves, suddenly dilated at the base; the other with lax spreading 
foliage.

2. Dicranum pungens, Hook. fil. et Wils. ; caule elongato subramoso, foliis secundis patentibus lineari- 
lanceolatis attenuatis convolutis apice carinatis serrulatis tenuinerviis, perichzetialibus elongatis convolutis, 
seta mediocri torta, theca inclinata oblonga curvula, operculo longirostro. (Tas. LIX. Fig. I.) 
Has. Lord Auckland’s group and Campbell’s Island; barren in the latter locality. 
Caules 3—4-unciales, robusti, erecti v. curvati, parce ramosi. Folia 4-5 lin. longa, conferta, patentia, subrigida, 
inferiora subsquarrosa, superiora dense congesta, supra carinata, marginibus apices versus dorsoque serratis, ple- 
rumque arcte convolutis, nervo tenui, luteo-viridia, nitida, siccitate supra medium torta; perichetialia intima 8 lin. 
longa, enervia, convoluta, integerrima. Sete interdum bine, 8-9 lin. longz, graciles, subflexuose, rubr, siccitate 
torte. Theca parvula, elliptico-oblonga, subcurvata, basi vix strumosa, rufo-brunnea, siccitate infra orem contracta. 
Dentes pro genere parvi, conniventes, demum supra medium fissi, ferruginei. Operculum (delapsum) theca longius,

This very handsome species resembles the D. Blumii, Schwaeg. (Suppl., vol. ii. pt. 2. p. 116. t. 185), inaccu- 
rately described as nerveless, but differs essentially in the form of the theca. D. Billardieri has shorter and broader 
leaves, and larger thecæ. In D. setosum, nobis, a nearer ally, the leaves are more setaceous and fragile, the nerve 
broader, and occupying the whole breadth towards the apex, the capsule is longer and more curved, the peristome 
larger and of a red colour, and the seta not twisted when dry.

3. Dicranum Billardieri, Schwaeg. ; caule elongato dichotome ramoso, foliis subsecundis basi lanceo- 
latis longe acuminatis denticulatis, theca strumosa, operculo longirostro. D. Billardieri, Schwaeg. Suppl. 
vol. ii. pt. 1. p. 70. t. 121. 
Var. 8, duriusculum ; caule humili fastigiatim ramoso, foliis magis rigidis attenuatis, nervo latiore, seta 
longiore. 
Has. Lord Auckland's group; on the ground and dead trunks of trees in woods, both varieties. 
The habit of the var. 8, which also grows on the more exposed uplands, is rather peculiar; still we can find no 
specific distinction between them. The D. Nove Hollandie, Hornsch., does not appear different from this species. 
4. Dicranum setosum, Hook. fil. et Wils.; caule fragili subramoso, foliis strictis fragilibus suberectis 
longissime lanceolato-setaceis apice serrulatis nervo latiusculo subexcurrente, seta longiuscula, theca oblonga 
curvata, operculo longirostro. (Tas. LVIII. Fig. V.) 
Var. 8, attenuatum ; caule flexili elongato ramoso. (Tas. LVII. Fig. V. 2.)
