indicates that of the Caprifoliacew there are sf enera aud 47 
species; of Rubiacee 26 genera and 86 species; of Valerianacew 
2 genera and 22 species ; of Dipsacacece | ewe and 2 species 
(naturalized) ; of Composite 237 genera and 1610 species. The 
part runs to 474 pages, or 72 more than in Part L Yet it is less
