APPENDIX II 151 



V. Lathyrus Aphaca is a European species and not acces- 

 sible, as far as the writer knows, to students in this country. 



The student may be shown pictures of this, and the rela- 

 tionship to the forms with imparipinnate and cirrhiferous 

 pinnate leaves brought out.

The Eucalyptus species are abundant in California and 

 are occasionally found in greenhouses in other parts of the 

 country. Dried and pressed specimens may be used where 

 fresh material is not available. 



IX. The so-called " Smilax " of the greenhouses (Myrsi- 

 phyllum asparagoides or Asparagus medeoloides} is very gen- 

 erally accessible all over the country. In studying this plant, 

 it is well to emphasize the fact that we consider a structure 

 borne in the axil of a leaf as a branch structure, and a struct- 

 ure bearing another structure in its axil as a leaf structure. 

 These points cannot be emphasized either too strongly or 

 too often.
