in Australia.'] INTRODUCTORY ESSAY. XCvii 



Of the 227 genera and 148 species here enumerated, by far the larger proportion are natives 

 of many other parts of the globe, including all those found also in Tropical India, but there is still 

 left a list of 38 species so notably characteristic of northern Europe, and so rare, if present at all, 

 in warm or southern Asia, that they at once challenge further investigation. These are, excluding 

 such marsh- and water-plants as Potamogeton, Scirpus, Isolepis, etc., and others, which inhabit all hot 

 countries as well as cold : —
