1. R. aquatilis, Limt. ; DC, Prod i. 26, A most variable speeies, 

 easily known by its stem either floating in water or creeping in halt-dried 

 mud, by its white flowers and very small ovoid carpels marked with transvex'se 

 wi'inkles. It is always glabrous, excepting sometimes the carpels and then 

 receptacle. In the Australian specimens the leaves are all submerged and 

 divided into numerous very fine linear segments ; in northern ones, there are 

 frequently also a few upper leaves spreading on the surface of the water, which 

 are rounded and more or less cut into 3 or 5 wedge-shaped, obovate, or 

 rounded lobes. Peduncles axillary and 1 -flowered. Petals 5 or sometimes 

 more, white, without any scale or spot at the base ; in most Australian speci- 

 mens they are scarcely longer than the calyx, and the stamens are very ieWy 

 but sometimes the petals are fully twice as long, and the stamens numerous.

2. R. Robertsoniy Beui/i, Allied to It. Millam, but distinguished 

 from all Australian species, and in some measure connected with some of the 

 European ones by its rootstock consisting of a cluster of short thick fibres. 

 Eadical leaves usually 2 or 3 in. long, pinnately divided in their upper por- 

 tion into a few rather distant naiTOW linear segments, which are often agaui 

 divided into 2 to 5 lobes, not unlike those of II. Millani, glabrous or Avith a 

 few silky appressed hairs. Flower-stems often 2 -flowered, 3 to 8 in. high, with 

 1 or 2 narrow and not much cut leaves. Flowers rather large, appearing 

 yellowish in the cUied specimens, but possibly white. Sepals not half so long 

 as the petals. Petals .^, obovate, with a small glandular pit. Achenes in
