This Eastern group is, relative to the other types, xerophytic. 

 Seventeen of the 49 species are inhabitants of sea-sands or sandy 

 soil, 12 more of dry banks 

 or ligbt cultivated ground. 

 Seven are water plants, 5 

 frequent marshes, 3 more are 

 usually found by river sides. 

 One, Lepidium Mrtum, is dis- 

 tinctly calcifuge, but on the 

 otber band Galeopsis Lada- 

 num is strongly calcicole, and 

 several others also prefer a 

 limy soU. None are moun- 

 tain plants, or even bill 

 plants, excepting perhaps 

 Sieracium horeale. 



The distribution in Great 

 Britain of the group is chiefly 

 "English," 12 out of 40 

 species classed by Watson 

 being of that type. Scilla 

 verna (Atlantic-Scottisb) is 

 the only species in whicb the northern element makes its appearance. 

 One is of Atlantic type, one of Germanic : the rest mostly intermediate 

 between English and British : in other words, slightly southern in 

 range. As compared with most of the groups, there is an increase 

 of British type, no less than 5 being purely British.
