OBSERVATIONS ON PLANTS, COLLECTED DURING 



MR. JOSEPH BRADSHAW'S EXPEDITION TO 



THE PRINCE REGENT'S RIVER. 



By Baron von Mueller, K.C.M.G., M.D., Ph.D., F.R.S. 



During the months of March, April, and part of May of this 

 yea^, Mr. Joseph Bradshaw, an enterprising Melbourne citizen, 

 conducted a private exploring expedition from Cambridge Gulf to 

 Prince Regent's River, whereby, for the first time, some of the 

 waters of that gulf became geographically connected with rivers 

 flowing into Brunswick Bay. Thus now only the upper portion 

 of Prince Regent's River became explored, although already 71 

 years ago Admiral Ph. P. King had discovered the estuary and 

 lower portion of that stream. With praiseworthy circumspect- 

 ness, in this expedition, unlike in many others, the leader of the 

 party made arrangements for securing botanic . material during 

 this enterprise, that particular task being specially entrusted to 

 Mr. William Tucker Allen. The results, which also in this 

 respect have rendered Mr. Bradshaw's expedition a very success- 

 ful one, have been recorded in the following pages, with the 

 prospect that during the soon commencing pastoral occupation 

 of the Prince Regent's River country also botanic along with 

 geographic exploits will be continued. 



Nymphaea coerulea, Savigny. 



Woodhouse River. 



From this locality is brought what appears to be a small-flowered 

 variety of the above-named species, which is generally regarded 

 as identical with N. stellata, but was published one year earlier. 

 The only flower obtained has the sepals and petals barely one inch
