Most of the type-specimens of Myrica callicomaefolia, M. rigida, and 

 M. fallax are preserved in the United States National Museum, together 

 with a great number of other fine examples that would ordinarily be re- 

 ferred to the first mentioned species. A careful study of this material 

 has failed to disclose any satisfactory Hne by which they may be 

 essentially separated, and hence, following CockerelFs suggestion, they 

 have all been combined under the name of Myrica drymeja, which 

 is the earhest specific name appUed to what was later called M. 

 callicomaefolia. Lesquereux himself suggested the possibility of 

 his M. fallax being referable — perhaps as a variety — to M. callico- 

 maefolia or M. drymeja, as it is now called. The species may be 

 known by the narrow shape with more or less inequilateral base and 

 numerous regular teeth which may be low or sharp and distinct. 



The single specimen from Florissant that was referred by Les- 

 quereux ^ to Myrica zachariensis Saporta, has not been found in the 

 collections of the United States National Museum. It is beheved to 

 be nothing but a large, nearly equal sided leaf of M. drymeja; in any 

 event, it is not to be distinguished from some in the collection that 

 were so referred by Lesquereux himself.
