126 A CONTBIEUTION TO, ETC. 



the colony, and that hitherto it has been confounded with S. 

 laciniatum. The pretty genus Halgania is brought before us in the 

 figure of H. andromedifolia, which has been collected at the Mur- 

 ray, Lake Tyrrel, and Phillip's Range. The flowers of a species 

 which I received from the Lachlan, were of a beautiful blue 

 colour, the brilliancy of which remained for a long time even in a 

 dried specimen. Of the Euphorbiacese, the Doctor has given a 

 figure of Bertya gummifera or oleifolia which deserves attentive 

 consideration from the faithful manner in which the minute parts 

 of the flowers are represented. By studying this species, a per- 

 son may easily recognise other species which occur twenty or 

 thirty miles from Sydney, especially . pomaderrioides, which I 

 found some little time since in a gully, near Bent's Basin. Dr. 

 Mueller, to whom I forwarded my specimen, regarded this as a 

 new species, and described it as such in the Eragmenta (vol. 4, p. 

 34). Tillaa purpurata is of the Crassulaceae, and in the Elora 

 Australiensis, it is noticed as one of E/. Brown's plants, Parra- 

 matta. There are two species of the genus here, but they are so 

 small and insignificant that they would escape the notice of any 

 one excepting the systematic observer. The figure of Haloragis 

 odontocarpa gives a good idea of the family with which it is as- 

 sociated, and will enable the student to make out the other 

 species which frequently occur in the damp places around us. I 

 have collected four or five, but they are not remarkable for any 

 beauty, nor do they appear to possess any important properties. 

 The last plant to be noticed is Panax dendroides of the Araliaceao. 

 This is common in the vallies of Southern and Eastern ranges of 

 Victoria, and it also grows in some parts of New South Wales. 

 P. elegans was collected on Ash Island by Miss H. Scott, and P. 

 sambucifolium is abundant on our creeks. P. Murrayi from 

 Twofold Bay, is stated by Dr. Mueller to be a very noble and 

 graceful tree, attaining the height of sixty feet. 



Dr. Mueller's lithograms must prove of incalculable advantage 

 to those who are engaged in the study of Australian botany, and 

 indeed to that large class of persons who, being content with a 

 general knowledge of matters, may rest satisfied with being able 

 to refer a plant to its natural order without entering into those 

 minute details which are the objects of systematic botany. Eor 

 the further accomplishment of this purpose, I think that a brief
