parts of a stamen, also any variation in length and 
union, if apparent. 
Study the number, form, and arrangement of the 
pistils. If more than one, are they entirely sepa- 
rate? Draw and designate the parts of a pistil, 
also sectional views of the ovulary showing one or 
more cells (ovule chambers), also the place of the 
ovule attachment (placenta). 
If the entire plant is small enough, make a careful 
drawing of it, or prepare a specimen properly 
mounted. 
Write floral formula. 
By means of an analytical key, e.g. Appendix III, 
determine the classification of the plant as to its

Norr. — A few suggestive “Life Problems” are 
given, and others should be made by teacher and 
pupil to fit each plant studied. In the study of 
entire plants, life problems should be especially 
emphasized. 
What is the habitat of the plant? Why? 
Are there any modifications in the plant structures 
to fit it to the conditions where it is found ? 
Explain the form and structure of the root, stem, 
leaf, and flower. 
Why is the plant or its parts smooth or hairy ? 
Why are the leaves and flowers arranged as you 
find them?
