116 ERYTHEA. 



gives free expression to his personal views, which will interest gar- 

 deners and cultivators, and perhaps some other people. Mr. Han- 

 sen, who is a German by birth and university training, occasionally 

 gets lost in the intricacies of the English language, as on page 187, 

 where he says : "And if we should be disappointed, it is con- 

 venience that names objects, and if my name hits the head of the 

 nail, and drives it home, too, let it remain and take root." In 

 the phrase of America-occidentalis, this might be called "a lofty dis- 

 regard of consecutive metaphor." The second supplement to the 

 enumeration was issued May 1, 1897; those who need it would do 

 well to address the author at Berkeley, Cal. 



The problem of the affinities of the simpler monocotyledons is 

 engaging the attention of Prof. D. H. Campbell, of Stanford Uni- 

 versity. In " A Morphological Study of Naias and Zannichellia" 

 (Proc. Calif. Acad., 3d ser., Bot. i. 1-62), he reexpresses his belief 

 that the monocotyledons and dicotyledons are of entirely distinct 

 origin, and if the view be accepted that there is a probable direct 

 connection of the monocotyledons with the pteridophytes, it is 

 among such simply-organized aquatics as Naias or Zannichellia, 

 that the point of contact is to be looked for. Naias and Zanni- 

 chellia are found to have many points of structure in which they 

 agree, but the relationship to each other does not seem, to the 

 author, sufficient to warrant placing them in the same family. 

 Both of the species investigated are found in California, and Pacific 

 Coast botany is to be congratulated upon the careful, detailed study 

 which Professor Campbell has begun upon plants which occur in 

 our region.
