(D) Banks
Certain bryophytes may almost be regarded as obligate to vertical banks, as Ditrichum flexifolium; but the majority of bryophytes found there at Port Pegasus are by no means restricted thereto.
(a) Coastal Banks
Omitting such as consist of bare rock, the only areas investigated were peaty banks on Rosa Island, at the “Freezer,” and at Fright

Cove in the South Arm. The only bryophytes found in this station only at Pegasus were Eriopus apiculatus, Orthodontium sulcatum, and Symphyomitra drummondii, but Ditrichum flexifolium, D. punctulatum, Rhacopilum strumiferum, and Rhizogonium novae-hollandiae were found there most commonly. Other mosses of this substratum were Campylopus clavatus and C. introflexus, while the following hepatics were listed: Balantiopsis convexiuscula, Bazzania involuta, Chandonanthus squarrosus, Chiloscyphus beckettianus, Cuspidatula monodon, Frullania rostrata, Isotachis lyallii, I. montana, Lophocolea subporosa, Plagiochila conjugata, P. radiculosa, and P. gigantea (one gathering).
(b) Inland and Upland Banks
This substratum on the Tin Range is usually weathered rock almost converted to clay. As a result, the vegetative cover is distinct from that on the peaty coastal banks. Here the lichens Baeomyces, Cladonia, and Stereocaulon are well represented and numerous seedlings of the nearby shrubs find anchorage. The commonest mosses on the bank margining the tramline on the Tin Range were Polytrichadelphus magellanicus and Ditrichum punctulatum with Campylopus clavatus common in places. Breutelia pendula, an undetermined Bryoid moss, Bryum obconicum, and a single clump of Bartramia norvegica were also listed.
Hepatics from this station were Anastrophyllum schismoides, Bazzania novae-zelandiae, Balantiopsis tumida, Chiloscyphus billardieri, Isotachis lyallii, Lepidozia pendulina, Lembidium tenax, Radula dentata, Riccardia spp., one bronze and the other deep green, and Schistochila pinnatifolia, a plant more usually epiphytic.
