290 I'ROCEEDINOl^ OF THK NATIONAL MUSEUM. vol.51. 



There appears to be some uncertainty as to whether Lyonothamnus 

 belongs to the Rosaceae or Saxifragaceae. Engler and Prantl place 

 it doubtfully with the former, while Sargent, Rydberg, and other 

 American authors place it in the Saxifragaceae.
