The definition of about 20 additional genera, either quite unknown or additional to 
Australian generic forms, is reserved for the fifth volume of the Fragments. 
The existence in Australia of fifteen ordinal or subordinal groups of plant s, either 
not noticed before, or without specific limitation ot their Australian representatives only 
indicated, was elucidated by the researches of this office. These groups are Oclinacese, 
Erythroxyleae, Hippocrates;, Brexiacete, Ilicinece, Homalinese, Ceratophyllese, Alangiacese, 
Styraceac, Vacciniem, Hvdrophylleae, Ehcagnese, Ephedrem, Musacese, Pontederiacea;. To 
these might be added Trithuriacese, a group altogether here, for the first time defined, and 
perhaps also Orobanchese, inasmuch as Orobanche cernua has become naturalized since a 
series of years in widely distant parts of South and West Australia. Further pliytological 
investigations of North-East Australia will undoubtedly add to this series members of 
other orders, especially of Indian type, as yet not recognized in the great complex of forms 
of vegetable life in this part of the globe. 
Hitherto approximately 2,000 of the 10,000 plants, which, with exclusion of Fungi, 
constitute the total flora of Australia, received their systematic position and exact appella- 
tion by the independent investigations of this department. If for our pliytological 
museum, which is already unique in the southern hemisphere, additionally the private 
herbarium of one of our leading botanical celebrities could be secured, a herbarium rich 
m autograplucal samples of such plants as were connected with the writings of authors 
published during the first decennial periods of this century, we would then possess a 
botanical institution second to but very few of the great metropolitan state herbaria of 
Europe, and excelling all in its Australian division. „
