THE 



CONVALLARIACEAE

(WITH PLATES VI AND VIl) 



The family Convallariaceae as used by Britton (2) is the 

 equivalent of the family Asparagoideae as it is used by Engler 

 and Prantl (12). Gray's New manual (20) has not made use of 

 either of the above family names, but has distributed the 10 genera 

 occurring within the family in the tribes Polygonateae and Parideae. 

 In this paper I shall refer to this group of genera as the Con- 

 vallariaceae. 



Of the 10 genera of the Convallariaceae occurring in the north- 



eastern part of the United States, Clintonia has been investigated 

 by Smith (23), Convallaria by Wiegand (24), Trillium grandi- 

 florum by Ernst (13), and T. recurvatum by Coulter and Cham- 

 berlain (11). I have in earlier papers reported on Smilacina 

 stellata (18) and S. racemosa (19), and in this paper report my 

 investigations on M aianthemum , Streptopus. Polygonatum, and 

 Medeola. The only genera occurring within this range which have
