84 The Vegetation of the Sea-coast. 
nant. Anzsotome intermedia, its leaves 76 cm or more in length, is a companion 
plant, but seems to prefer the debris as a station. Eossöcks of Poa Astom, 
on the rock, and erochloe redolens, on the debris, complete the association. 
Further to the S., the Ce/misia may be absent, but'the Anzsofome continues 
on cliffs to beyond Curio Bay. 
4. Okarito Bluff. 
The substratum consists of old morainic material. Where water drips there 
are great sheets of Gnaphalium trinerve and in,places G. Lyalli. The liane 
Metrosideros scandens, clinging closely to the cliff, occupies many square metres. 
Blechnum capense, the fronds hanging downwards, forms extensive colonies. 
The following shrubs occur, both as a wind-shorn scrub and dotted about — 
Coriaria ruscifola, Melicytus ramiflorus, Fuchsia excorticata, Rapanea Urunllei, 
Veronica salicifolia, V. elliptica, Coprosma lucida and Olearia avicenniaefolia. 
Arundo conspicua and Phormium tenax are common. Besides several ordinary 
herbaceous halophytes, the following herbs or grasses are present: — Asple- 
nium lucidum, Poa Astoni, Gunnera albocarpa, Nertera depressa, Lobehia anceßs. 
t the base of the clif, on the debris, is Paesia scaberula and Euphorbia 
glauca. 
| 5. Cliffs S. W. of Stewart Island. 
The vegetation of these cliffs is called attention to because they are the 
station of Celmisia rigida and Anisotome flabellata, two endemic Stewart Island 
plants. C. rigida grows in peaty ground on the summit of the cliffs. The 
Anisotome is a chasmophyte confined to rock. Its roots are of an extraordinary 
length. The pale-green, pinnate, thick, fleshy leaves, 2.5 cm long, are in small 
rosettes, Ken pressed closely together, are = flattened to the rock. 
6. Rock-debris associations. 
in the neighbourhood of Cook Strait, Wellington, and on Kapiti Island 
there are coastal slopes of stony debris. The stones are angular and vary 
in size from pieces some 16 cm X ı2 cm to small fragments mixed with coarse 
sand. Although the surface is generally quite ‚dry, at 5cm deep there is 
always a considerable amount of moisture. W. of Island Bay, where the neigh- 
bouring slopes are occupied by Bern the anbien a m Br wa 
tation consisting of Poa caespitosa where most c ö 
 plexa as a mat, Acaena, novae-Zealandiae, Epilobium nnae-Zealandiae, Aeiphylla 
squarrosa and Calystegia Soldanella. 
The Kapiti Island debris-slope is frequently quite bar but, elsewhere, it 
is occupied by an open association of heath-plants, e.g. — Arundo conspicua, 
Muehlenbeckia Eee and Cassinia leptophylla (Plate IX, Fig. 14).
