The Phanevogamia of the Mitta Mitta Source Basin. 31 



forms a procumbent shrub, hard- wooded and strongly 

 spinous, the berries larger, and paler purple in colour 

 than the arboreous lowland form. — See pt. 1, p. 5. 



Pittospore^e (R. Brown). 



Marianthus procumbens (Bentham). — Is occasionally met 

 with on the open spurs from the Dividing Range 

 toward the head of Livingstone Creek, where the 

 metamorphosed schists merge into the Silurian slates ; 

 at elevations of 3000 to 4000 feet. 



Billardiera longinora (Labillardiere). — In scrubby situations 

 along the Dividing Range, on Silurian formation, 

 particularly where there is much vegetable mould, 

 climbing over branches of Lomatia ilicifolia and 

 Pittosporum bicolour ; it ascends, near Mount Phipps, to 

 4000 feet. 



Droseeace^: (Salisbury). 



Drosera auriculata (Backhouse). — On damp, grassy, and 

 mossy depressions at the summit of Mount Sisters ; 

 3000 to 3600 feet elevation ; in metamorphic or intru- 

 sive granite formation. 



Drosera peltata (Smith). — Common on damp pastures near 

 Omeo, at elevations of from 2000 to 3000 feet. In an 

 interesting paper read before the Field Naturalists' 

 Club, by my friend Mr. Sullivan, of Moyston, the fact 

 of the absorption of insect substance by the leaves of 

 our Australian Droseracese is questioned, and the 

 results of experiments detailed. I have now to state, 

 that recent observations made by me by the aid of a 

 powerful microscope on the leaves of D. peltata (and 

 upon which insects had been smothered by the infolding 

 of the tentacular hair and the secretion of a viscid fluid 

 from their terminal glands), clearly indicated absorption 

 taking place through the cells forming the cuticle of the 

 leaf, apparently by a process of endosmose. The insects 

 were representatives of the Diptera. 



Hypericins (J. de St. Hilaire). 



Hypericum Japonicum (Thunberg). — All over the undulating 

 ranges, near Omeo, on mica-schist formation; on the 

 Omeo Plains, alluvium, and ascending on the fiats along 

 the upper course of the Victoria River ; granitic areas, 

 up to 4000 feet.
