 onotis, microcachrys, diselma, athrotaxis, pherosphse- 

 ra, bellendena, cenarrhenes, archeria), only acradenla 

 and agastachys belonging seenaingly to the lowlands, 

 but show at once a fondness for a wet, insular clime. 

 The few Tasinanian genera, represented besides only 

 in Victoria, are richea, diplarrhena, drymophila, jun- 

 cella. In the Tasmaniau highlands flora endemic 

 shrubby asters and epacrideise, and the singular endem- 

 ic pines of various genera, constitute a marked feat- 

 ure. A closer and more extended inquiry into the 

 geological relation of great assemblages of vegetation 

 will shed probably more light on the enigmatic laws 

 by which the dispersion of plants is ruled. Austra- 

 lian forms predominate also in Tasmania, at snowy 

 heights, so Eucalyptus gunnii, E. coccifera, and E. 

 urnigera. The famous Huon-pine (Dacrydium Frank- 

 lini), the Palmheath (Richea pan danifolia), the celery, 

 topped pine (Phyllocladus rhomboidalis), and the de- 

 ciduous beech (Pagus Gunnii) are among the most 

 striking objects of its insular vegetation. Mosses, 

 lichenastra, lichens, and conspicuous fungs abound 

 both in alpine and low regions ; indeed, cryptogamic 

 plants, except Algs and microscopic fungs, are no- 

 where in Australia really frequent .except in Tasmania, 

 in the Australian Alps, and in the Pern-tree glens of 

 Victoria and part of New South Wales. The Musk- 

 tree (Aster argophyllus) of Tasmania and south-east 

 Australia is the largest of the few trees produced by 

 the vast order of compositse in any part of the globe, 

 while Prostanthera lasianthos, its companion, exhibits 

 the only real tree known in the extensive family of
