12 POPULAB, GEOGRAPHY OF PLANTS. 



1851 : there is something very elegant in the appearance of 

 its shining, almost silk-like, white seed-down. Then there 

 are numbers of true Grasses to be met with, though not, 

 of course, clothing the country as ours do; and to judge 

 of the rest by one specimen (Pkippsia algida), they have a 

 very starved look. Alpine Pox-tail Grass (Alopecurus al- 

 pinus) is another; it also grows on some of the highest 

 mountains in Scotland. 



The Field Eush (Luzula campestris) is one of the plants 

 which are met with in the Polar regions. There is also a 

 very pretty plant in which a strong family likeness may be 

 traced to our common Heaths, arid which is a species of that 

 family, called Andromeda tetragona, with imbricated leaves, 

 and blossoms like little white cups, growing on rather long, 

 hair-like stalks. The same resemblance may be seen too 

 in another heath, called Pyrola, which is a somewhat larger

 peal of bells, with the clappers (the black tips of the pistil) 

 just hanging out : we have species of both. Then there is 

 a small marsh-growing plant, called Till&a aguatica ; and 

 the little Mouse-ear Chickweed (Cerastium alpinnm) of 

 course will be there : it belongs to a hardy family ; some
