the " Climbing Sundew," Drosera Menziesii ; the " Love 

 Creeper," Comesperma volnhile; and the "Twining Fringe-lily," 

 Thysanokts Patersoni, are those most often noticed. 



The orchids found here are mostly of genera not represented 

 in the ' leptospermetum ' — Thelymitra, Diuris, Prasophyllum, 

 Eriochilus, Microtis, &c. The " Spider Orchid," Caladenia 

 Patersoni, is equally at home in both places. The "Tiny " and 

 the " Bearded Helmet-orchid," Pterostylis parviflora and P. 

 barbata, are seeemingly the only ones of the genus preferring 

 the scrub-land. The " Yellow Hood-orchid," Thelymitra 

 antennijera ; the " Larger Glossodia," G. major ; the " Flower 

 of Sadness," Lyperanthus nigricans : the " Tall Leek-orchid," 

 Prasophyllum elatnm ; and a couple of the Diuris, are the most 

 abundant. The only grass conspicuous is the " Fibrous 

 Spear-grass," Stipa semiharbata, which may be seen waving 

 its plumes well above the shrubs. The formation is too close 

 for grasses, but the " Kangaroo Grass," Anthistiria ciliaia, and 

 others, occur here and there in favourable situations. Ferns, 

 too, apart from the bracken, are rarely met with, the " Screw 

 Fern," Lindsaya linearis, alone prevailing widely. 



On account of the sandy, porous nature of the substratum, 

 there are few places where permanent water is found. Still, 

 there are many localities where it persists during a great portion 

 of the year, and where the soil never becomes quite dry Here 

 may be studied examples incompletely representing the various 

 formations cf water-loving plants — ' hydrophytes ' and 

 ' helophytes,' or marsh plants, and many of their adaptations, 

 such as creeping axes, slenderness of stem, lengthening of inter- 

 nodes, deficiency of root formation, and peculiarity of leaf shape 

 and structure, can be noted. 



Of the true aquatic plants, the free-floating " Lesser 

 Duckweed," Lemna minor and the 'Red Azolla/ A. rubra, 

 alone represent the Pleuston (hydrocharid formation). The 

 fixed water plants (Benthos), constituting what is termed 

 the " Limnaea formation," with leaves submerged or floating, 

 are the " Floating " and " Curly Pond-weed," Potamogeton 

 natans and P. crispus ; Ottelia ovalijolia ; the yellow-flowered 

 Gentian, Limnanthemum. exaltatum, oftener seen in blossom 

 after the water has dried up ; the " Giant Arrow-grass," 

 Ttiglochin procera, with long, ribbon-like leaves, partly sub- 

 merged and part floating ; the " Water Starwort," Calli- 

 triche verna ; the " Water Milfoil," Myriophyllum variifolimn, 

 forming "social" growths, often completely filling up a 

 pond, and showing a difference in submerged and emerged 

 leaves ; and the beautiful little " Branching Bladderwort," 

 Utricular ia dichotoma, oftener noticed growing in wet ground. 



The plants normally rooting in water or wet soil, but without
