The HanESayEnie consists of an even turf of extreme density ”) owing 
to the plants having their rosettes or leaves pressed close to the ground. Its 
composition is not uniform throughout, but more or less distinct sub-associations 
may be recognized, defined by the dominance of S. radicans, C. dieica or. 
P. Hamiltonii respectively, though the combinations merge one into another. The 
round, green cushions of Zuphrasia repens are everywhere, each about ı2 cm 
in diam. which, when thickly covered with their small, snowy flowers are most 
striking. Gentiana saxosa, too, in full.bloom, is equally conspicuous. The 
physiognomy of the turf itself depends upon which species is dominant. The 
dense shining rosettes of P. Hamiltonii, all touching, the leaves glossy-green. 
but blackish-brown at the base, covering the ground to the exclusion of all 
else, are a remarkable sight. Colonies of Rumex neglectus make green patches; 
danke of C. diorca lends a reddish-brown colour to the turf; the tiny 
starry flowers of Asperula perpusilla betray its presence, otherwise hardly 
noticeable. Increasing wetness of the ground brings in abundance of Monria 
Fontana, and Crassula moschata occurs in profusion, fringing poöls. Blecnum 
durum and Asplenium obtusatum, their fronds flattened to the soil, are every- er 
where common; tussocks of Scirpus nodosus are occasionally plentiful, or those . 
of Carer appressa may make a pure growth, and, in some places, the still. : 
taller Fuegian C. zrıfida will occur. 
On the low flat sandy ground to the W. of the New River Estuary, the 
association is allied to coastal-moor, on the one hand, and dune-hollow, on | e 
the other; E. repens, P. Hamiltonüi »Claytonia alte and Nertera Bal- 
Ffouriana, for example, represent the moor, and Gunnera EBEN: Geranium
