ish red. The substance is rigid and membranous, and the plant does not 

 adhere to paper in drying. 



This lias so much the colour and the external aspect of Kuet- 

 zingia canalicidata, that I formerly described it as a species of 

 Kuetzingid; nor till I had examined it more carefully, under 

 the microscope, did I notice the difference in structure. The 

 structure of the membrane is exactly that of an Amansia, and 

 the fruit, so far as known, sufficiently accords. Most Amansia 

 however have involute apices to the segments and their divisions ; 

 and the stichidia rise, not from the lamina, but from the lateral 

 teeth. Here, as in Kuetzingia, the apices are straight, and the 

 stichidia spring from the surface of the leaf. 



This appears to be a very rare plant. I only obtained a 

 single specimen during my visit to Australia, and it has not 

 been sent to me by my indefatigable friend and contributor Mr. 

 Clifton. Its characters are so marked that it cannot be con- 

 founded with any other Australian species.
