Colour no doubt has been green, but the only specimen yet seen is bleached 

 quite white. Fruit unknown. 



The Plate here given is drawn from a unique specimen, now 

 preserved in the Herbarium of the University of Dublin, and 

 which was given to me in 1854, by W. Ashford Sanford, Esq., 

 of Nynhead Court, Somerset, at that time Colonial Secretary of 

 Western Australia. Mr. Sanford had it from its discoverer, the 

 daughter-in-law of Mr. James Drummond, who has so largely 

 contributed to our knowledge of the plants of Western Australia. 

 The original specimen is bleached to a creamy whiteness, and 

 strikingly calls to mind some specimen of old point-lace ; and as 

 it is of a tough substance and sufficiently strong, it might be 

 adapted to the use of the toilet by merely affixing it to a " foun- 

 dation" of net. I have taken the liberty to strike the Plate in 

 green, but in other respects the drawing is a faithful copy of the 

 specimen. 



The genus Struvea was established by Soncler, in 1845, on an 

 Alga {S. plumosa, Sond.) brought by Preiss from Western Aus- 

 tralia, and which is very abundant on the reefs at Rottnest 

 Island. In a future number I propose to give a figure of it. 

 At present I shall merely point out the characters by which our 

 plant is distinguished from it. These are, the much greater size 

 of the frond, the more complicated pattern of the lacework, and 

 the greater proportional length of the cells of which the lace is 

 composed. 



I trust that Mrs. Drummond, or some other resident at 

 Champion Bay, may again find it, and communicate duplicates 

 that may enable me to distribute specimens among the subscri- 

 bers to this work. '
