Tbii.-^, Kao'abara has 7 species, 5 in common witli others ; Yuasa 

 lo, (S in common witli others ; Katsuragawa 1), 7 in common ^vith 

 otliers ; llyôseki 15, 10 in common with others ; and Kaisekiyama 

 N, 7 in common with others ; while Yoshida-vashiki has oiilv 1, 

 represented in many other localities, and Choja 2, 1 of wdiich is the 

 same as that of the precedinu' place. Such heinu" the case, the floras of 

 all tlie places except the last may he safely looked iip(m as helonuin"' 

 to the Sîime epocli. Of Choja we shall speak more l-ater on. 



Having' thus proved tlie close relationship existing betweeii the 

 floras of the respective b3ca]ities, the next question is their age. Except 

 Choja, and an unknown locality yielding MacrotrvNidpteris manjuKita^ 

 the number of plants collected in various localities amounts to '2b 

 species and 2 yarieties. Of these 2o species, 3 are not determimdjle, 

 and 15 are peculiar to Japan and indeed to the formation in question; 

 so that what might be aya liable, if eyer ayailable, for the fixing of the 

 age would be the folio wino' :
