That is, 87 of our 853 extra-European phenogamous gener 
or 24 per cent are common to Western North America, and 101, 
or 28 per cent to Eastern temperate Asia. Four per cent more 
of our characteristic genera are shared with an antipodal region — 
than with the neighboring district of W. N. atiniee ‘And the : 
number is likely to increase; for we know far less of the flora of - 
Japan and China than of California and Oregon. Drs. Hooker © 
and Thomson’s large Himalayan collections, now in the course 
of distribution and publication, will probably add several more 
to the list. Twenty-nine of these genera, or 8 per cent, are 
regions, b 
common to all three of these 
Our 194 genera which are neither European, N
