altitude of 1,400-2,000 feet, there is a light-coloured, light- 
textured, rather shallow, almost skeletal soil developed 
oil alaskite, boulders of which are scattered here and 
there over the surface. The trees are large and form a 
relatively dense canopy; Gasuarina lorulosu occurs scat- 
tered as an understory tree. There is a well-developed 
underwood, nowhere really dense, of a number of shrubs 
and seedling trees, of which the most prominent are 
. 1 croti ich < aggreijala . and Oxylobium trilobntwm (with 
spiny leaves), Monotoca scopuriu Persona in Milchellii 
(a geebung), Indigofem australis (a native indigo), 
Tcphrosia purpurea and 11 area acutifoliu (liovea). There 
is a rich and varied ground flora, of which the commonest 
members are the grasses (2-8 feet high), Tliciueda aus- 
tralis, I’on australis, (Ujinbopoyon nfrartus (barb-wire 
grass). Diyitaria sp., and Microtar net stipoides: also 
Lcpulospcrmct lalcrale. Didisrits iiicisits, Goode nia rotundi- 
foliU; Desmodium rhytidophyltum, f). brucligpodum, Tleli- 
chrystim braid cut uni (yellow everlasting), Dianella 
cocrulea (blue-berry lily). Twining plants present are 
Glycine cluudishna, Hardenberi/ia violacca ( H . bima ev- 
ict a, IP monophtjlli; ; sarsaparilla ), Kenned ya rubicuiida, 
Cissus apin' lift (a native grape), and P uslreph ns latifoUus 
var. augustif alius. At its lower edge this forest touches 
on rain-forest with an ecotone in which Tristamu ronferta 
(scrub box), Brcichychiton bidwiltii, Gynniostachys anceps 
and Gure.r deelnmta are noticeable. On very rocky places 
on the hillsides are to be found a number of herbaceous 
plants more or less restricted to these places. The ferns 
Dry nai hi ni/idulii and Notholaena ihsfans and the labiate 
Pled ninth us uu si rails are specially characteristic, and the 
orchid Deiidrobiuiu kruijianHin is usually to be found on 
rock faces. Some other noteworthy plants of these rocky 
places are Crassnla sielicrierna, Ihe ferns Davallia pyxidata 
(hare's-foot fern), Adiantuin hispid-alum, Doodia hete.ro- 
phylla (rasp fern), and Pyrrliosui rwpcstris, Dendrahiuni 
ling ai forme (tongue orchid), etc. 
Closed forest occurs in some places on the hillsides, 
frequently in gullies. Sometimes it is very close to 
time rain-forest in character, hut epiphytes are relatively 
scarce and the lawyer vine (Gain tuns muclleri) is but. 
rarely seen. Also the hoop pine ( Araucaria cunningharnii) 
is common to abundant in places — much more common
