1. Ditrichium australe, Mtt. 1. c. (Cynontodium). Lophiodon strictus, 
Uooh.f. et mis. FI. Antarct. 130, t. LIX., Fig. 1. 
In dense fulvous tufts, Avith old eapsules, Moseley. (Lord Auckland’s and 
Campbell’s Islands.) 
In all the specimens referred to tins species the dry young foliage is fulvous, the 
older brown or black ; the terminal leaves are frequently longitudinally tAA'isted, 
othenvise their direction is the same as when wet ; the loAver portion of the leaf is 
in outline of an elliptic oblong figure, from which the nerve is continued in a straight 
line, and is rather suddenly carried out so as to appear without a margin of leaf ; 
a transverse section shows it to be concave above and convex beneath ; the apex is 
abrupt, rounded, and nearly flat, so as to appear as if dilated, and, as stated in the 
Flora Antarctica, the species is distinguished from most of its allies by this par- 
ticular. The substance of the base of the leaf is composed of elongated cells which, 
although shorter towards the top of the dilated portion, are not dcirsc, so that the 
entire expansion is of a pellucid fulvous colour, the nerve being everyAvherc smooth, 
wdtii a fcAV small teeth at its apex.* 
2. Ditrichium Hookeri, C. Muller Syn. /., 450 (Leptotrichum). 
Eoyal Sound, with old capsules and young setse, Eaton. 
3. Ditrichium conicum, Mont, in Ann. Sc. Nat. Ser. 3, iv. 100. (Aschi- 
stodon.) 
Xear Vulcan Cave, barren, Eaton. 
The imbrication of the leaves at the apices of the stems, Avhen dry, so as to form 
an erect or curved point, renders this species not difUcult to recognise in a barren 
state. 
1. Asiothecium vaginatum, Uook. 3Insc. Exot. t. 141 (Dicranum). 
* In the Journal of the Linnean Society, Sept. 1859, there wa.s confused with ihe Leptotrichum australe, 
therein mentioned, the following apparently distinct species, — 1). punctulatum, Mitt. ; dioicum ? dense caespi- 
tosum, dichotome ramosum, folia inter se remotiuscula a basi erecta amplexante oblonga cellulis inferiorihus 
elongatis superiorihus abbreviatis rotundatis obscuriusculis veluti punctatis, subito in subulam patentem 
inferne canaliculatam apice angustam planiusculam denliculatam minutissime scabridam sublmvem cellulis 
punctulatis areolatam producta, pericluetii alia basi Latiora et longiora parte subulato patentiora, theca in 
pcdunculo breviusculo rubro parva ovali-cylindracea erecta leptoderma fulvo-fusca. Flos masculus in ramis 
terniinalis, ovatu.s, e basibus foliorum dilatiitis apice retusis vaginantibus involucratus. Distichium capilla- 
ceum, FI. N. Zealand, II., 73. 
Hub. — New Zealand, Dr. Lyall. Great Barrier Island, Hutton and Kirk. Fagus Forests, Hopkins, 
Dr. Haast. 
In size colour and general appearance very similar to D. australe, having also the same, but narrower, 
flattened apices to its leaves; in the recurvation of the subulate portion from the top of the erect base it 
resembles D. capillaceum, and for this species Dr. Lyall’s barren specimens were mistaken, although the 
leaves arc not distichous, .but so disposed that each fifth leaf occupies the .same vertical position on the stem 
as the first counted from ; the outline of the dilated base is not oval-elliptic as in D. australe, but oblong 
obtuse. The fruit in an old state is present on Dr. Haast’s specimens ; accompanying these fertile stems 
were many conspicuous male flowers, which do not appear to arise from the lower parts of fertile stems, but 
seem to be really distinct male plants.
