all alpine (milligania, campynema, hewardia, ptery- 
gopappus, tetracarpzea, anodopetalum, cystanthe, pri- 
onotis, microcachrys, diselma, athrotaxis, pherosphe- 
ra, bellendena, cenarrhenes, archeria), only acradenia 
and agastachys belonging seemingly to the lowlands, 
but show at once a fondness for a wet, insular clime. 
The few Tasmanian genera, represented besides only 
in Victoria, are richea, diplarrhena, drymophila, jun- 
cella. In the Tasmanian highlands flora endemic 
shrubby asters and epacrides, 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 pandanifolia), the celery- 
topped pine (Phyllocladus rhomboidalis), and the de- 
ciduous beech (Fagus 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 Fern-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 composite in any part of the globe, 
while Prostanthera lasianthos, its companion, exhibits 
the only real tree known in the extensive family of
