DESCRIPTION OF PLATES. 



Platk IV. 



Fig. 1. View of East Hill looking cast along the col from the slope of 781 Hill. 

 The north face (left) has a shrub flora and much bare rock, while the south face has a 

 covering of low trees of Casiiariiia siricia and Melaleuca parviflora. The trees in the fore- 

 ground are Casuarinas. 



Fig. 2. 781 Hill from south looking across a granite basin at the head of Main Creek. 

 The vegetation in the foreground is Artlirociieiiiitiii halocuemoides, var. pcryranulatum, and 

 Mescmbrxanthemum anstralc. Immediately behind the basin are prostrate trees of Melaleuca 

 hahiiaturorum. Beyond is a scrub woodland of Melaleuca parviflora, passing into Casuarina 

 stricta woodland about half-way to the summit. The slopes of 781 Hill show the characteristic 

 areas of bare granite. 



Plate V. 



Fig. 1. Casuarina stricta woodland with undergrowth of Leucopogoii Richei. To the 

 right is the edge of one of the bare granite areas. South face of 781 Hill. 



Fig. 2. Summit of East Hill from the north side of col. Casuarina stricta on 

 summit amongst granite tors, with Melaleuca parviflora, Olearia ramulosa, and Lcucopogou 

 Ricliei as shrubs. The Casuarinas disappear about the level of the large tor right of the 

 middle. The shrubs in the foreground are Rhagodia crassifolia. 



Plate VI. 



Fig. 1. x4triple.v paludosum consocies on rubble plain, showing in middle distance sharp 

 junction with community composed of Rhagodia crassifolia at the base of a steep rise. About 

 the level of the granite boulders Rhagodia is replaced by the Olearia-Leucopogon thicket 

 community. On the skyline a few trees of Casuarina and Melaleuca parviflora. South slope 

 of East Hill, Northern Pearson. 



Fig. 2. Atriplex paludosum consocies in foreground; behind is the lower course of 

 Main Creek, with a dense scrub of Melaleuca hahnaturorum, the "paper bark" of which makes 

 the trunks appear white. In the background is the south-east face of 781 Hill, with scrub 

 woodland of Melaleuca parviflora on the lower slopes and Casuarina stricta in the upper part. 

 Note the large areas of bare granite on 781 Hill. 



Plate VII. 



Fig. 1. Atriplex paludosum consocies on rubble plain with local patches of Rhagodia 

 crassifolia (darker-coloured foliage) in hollows. Beyond is the course of Main Creek, with 

 Melaleuca halmaturorum intersecting a scrub in which Melaleuca parviflora is dominant. The 

 tors on the skyline, right, are at the south-west corner of Northern Pearson. 



Fig. 2. Melaleuca parviflora scrub and Atriplex paludosum consocies junction on north 

 bank of Main Creek. Note the patches of Mesembryanthemum aequilaterale with Pelargonium 

 australe, the first colonists of granite rubble in the scrub woodland series. 



Plate VIII. 



Fig. 1. Atriplex cinereuin on shore forming mounds of blown sand. Behind Frankcnia 

 i-auciflora, dark leaves, also holds sand. Higher up the slope mixed communities, including 

 Lef'idium foliosum and Olearia rantulosa. In right hand corner portions of two hair seals 

 (Arcteocephalus fosteri) can be seen. 



Fig. 2. Foreground travertine plateau flora on Southern Pearson: plants, Atriplex 

 cinereum, Mesembryanthemum australe, Threlkeldia, Enchylaena, etc. Middle Pearson, with 

 the landing place seen behind — note the abrupt (south-west) face and gentle slope of the 

 east side. The travertine plateau of this island is well seen. To the right is the south-west 

 coast of Northern Island, with 781 and North Hills. 



Plate IX. 



Fig. 1. Annual plants (Senecio lautus and Apium prostratum ) now dead and Enchy- 

 laena tomentosa on travertine plateau of Middle Pearson. Behind Junction of talus slope 

 with Olearia-Leucopogon thicket on boulder slope. 



Fig. 2. Foreground Atriplex paludosum on talus slope to North Bay, Northern Pearson. 

 A watercourse runs from right to left marked by occasional bushes of Melaleuca parviflora. 

 This watercourse (North Creek) is fresh. Beyond is bare talus with large spreading bushes 

 of Rhagodia crassifolia. The rocky slope behind has an open shrubby flora, chiefly Olearia 

 ramulosa, Rhagodia baccata, with some Leucopogoii Richei. Carrea speciosa. Mesem. 

 aequilaterale, and Pelargonium on exposed parts with Selcranfhus pungens and Poa.
