PHYSIOGRAPHY OF AUSTRALASIA. 



"337 



flowered Chamascilia, C&sia and Dianella, the D. Tasmanica particularly robust, the yellow- 

 racemed Bulbine, the purple-flowered Artkropodium, and accompanied in various colouring 



by numerous terrestrial species of Orchids, mainly- 

 referable to Caiadenia, Tliclymitra, niitris, Praso- 

 pliylhim, Plerostylis and Microtis, the latter two 

 with green flowers, while Ptcrostylis presents a 

 labellum, jerking at the slightest touch to entrap 

 insects for the functional benefit of its flowers, the 

 rare Caleya carrying on a somewhat similar man- 

 oeuvre for an analogous purpose. The leafless 

 Dipodiunt must be regarded as the tallest of all 

 Orchids of South-eastern Australia, quite a proud, 

 and by no means as yet a rare plant, though far 

 less frequent than the prettiest of the species of 

 the order there, the "Spider-Orchid" (Caiadenia 



Pater soni ). 



The Victorian Flora 

 remains in this respect 

 remarkable, as it still in- 

 cludes representatives of 

 genera, which nowhere 

 else recede so far from 

 the tropics. Thus the 

 great lily-like Criniitn 

 and a splendid Jasmine, 

 with the arboreous Cap- 

 par is Mitclielli, still grace 

 the banks of the Murray 

 River. So/an inns, J/iv- 

 sine and Aviccnnia ex- 

 tend nearly to Port Phil- 

 lip. Eugenia Smithii, the 

 " Lilly Pilly " of the col- 

 onists, appears as far as 

 Lake King in Gippsland, 

 and Alstonia constricta, 

 the " Bitter bark " of the 

 interior, occurs in the 

 north-west of the colony. 

 New South Wales and 

 ASTER ASTEROTRICHUS (Olearw Asterotricha). Queensland. The lovely 



I'*icldia gives us among Gesneriacca' also a stray plant from the hot zone, decorating the 

 trunks of our fern-trees, while in Eastern Gippsland still occur trees or shrubs or 

 climbers of Eupomatia, Acronyc/i/a, Sarcopctahtm, Stephania, Fiens, Claoxylon, Oma/atit/ins,
