322 PLANTS GATHERED DURING MR. FORRESt's EXPEDITION. 



leader of tlie expedition. Vnrioiis Cassia of the series of C. arte' 

 T//i.si')l(ks, so abundant towards Lake Torrens, the Barkoo and Darling 

 livers, were also found. 



Other plants in the collection deserving some notice arc Sitla 

 cnlychymerda, Abutllon cryptopetalum, and Cassia plciirucarpa. Jas- 

 riiinum calcarinm was previously only known from between the Moore 

 river and Shark Bay, and from J. Macd. Stuart's track, wliile Ilakca 

 gramMatophylla, a rare and splendid South Australian species, has not 

 l)een previously recorded from any West Australian locality. The 

 tree compared by Mr. Forrest to the AVeeping Willow is Fittosponmi 

 phillyroides, which stretches across the continent in most directions 

 from the settled parts of West Australia. Of Slack/iousia puhescens, 

 an exchisively West Australian species, an aberrant variety was 

 brought. The tall climber with pods, gathered by the natives for 

 food, is the " Daubah " of Sir Thomas Mitchell's journal, Marsdenia 

 LdcJiJiardtiana, which I have traced myself to the Murray river, 

 Sturt's Creek, the rear of Carpentaria, Lake Torrens, and the Burdekin 

 river, and which Mr. Oldfield saw also on the river Marchison. 



The West Australian natives, who, as Mr. Fjrrest informs us, call 

 the fruit " carcular," eat the yoimg seeds and the inner part of the 

 pericarp. 



The most interesting plants in this collection are a new Ptilotus and 

 EiiosteDioH. 'WiQ latter is of an eastern type, allied to E. scaler •, 

 and in bestowing on it as a speciiic appellation the honoured name of 

 Lieut.-Colonel Bruce, the Acting Governor of West Australia, I 

 wish publicly to record my appreciation of the philanthropic and sci- 

 entific generosity which prompted his Excellency and his advisers to 

 send out this last expedition in the cause of a lost traveller and for 

 the advancement of geography. The new Ptilotus resembling P. lali- 

 f alius, I wish to bear the name of the Hon. Captain Roe, R.N., under 

 whose immediate control not only Mr. Forrest and his companions 

 were sent out, but who, moreover, for nearly forty years has been 

 identified with the territorial and naval explorations of the Australian 

 continent, more particularly its great western portion, over which he 

 held so long and so worthily the administration of the Survey Depart- 

 ment, and who on this occasion is entitled to special consideration, as 

 he took an active share in the elucidation of West Australian plants 

 as far back as the time of Baron von Hiisel's visit.
