rotia are foimd in t}i'^ Dakota Gro\ip of the Creta- 

 ceoiis (9) and that Plamamelis and llamamelidanthiiun 

 are found in Eocene strata in northern Europe, so 

 that the family had formerly a much more extended 

 ran^e than at pr-esent. 



I have usually found Hamamelis on rather 

 steep hillsides with a northern exposure, or more 

 rarely on low ground along streams. It is said to 

 grow abundantly on mountain tops in Pennsylvania 

 and western Maryland, and Cowles (6) reports it as 

 grov/ing on sand dunes near Chicago. From his de- 

 scription, however, it is doubtful if the seed had 

 germinated in these dry localities. It thus has a 

 very restricted range and seems to seek the best po 

 jitions in which to procure moisture and prevent 

 transpiration.
