ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 19 



Fertile seed is usually produced abundantly in the genus, and 

 germinates readily. 



VII. Sources of Material. 



It may be well to indicate from what sources the material used 

 in the present study was obtained ; this will enable any student of 

 the genus who comes after to know what fields were explored and what 

 were not, and will indicate the directions in which possible fresh 

 material may be sought. The following paragraphs must also serve 

 as a very inadequate acknowledgment of invaluable assistance received 

 from many quarters in the supplying of living material.
