THE FLOWER. 75 



of the ovules, and make out as much of their structure as 

 possible. 



III. Construct a diagram of the flower. 1 



NOTE. A correct diagram necessitates a careful study of the relation 

 of every part of the flower to every other part. It should be drawn with 

 geometrical precision, representing the parts of each whorl so as to show 

 their number, arrangement, relation to other whorls, and to some extent 

 their union or separation. Properly constructed, such diagrams serve 

 an important purpose by facilitating the comparison of the permanent 

 morphological features of flowers of the same and different families. 



IV. Ascertain whether the. flower manifests any physio- 

 logical adaptations. 



1. Is there anything protective in its form, position, or 



structure ? 



2. Enumerate its attractive features. 



3. Is there anything to indicate whether cross- or self- 



fertilization takes place ? 



NOTE. A satisfactory answer to this question may require 

 more experience than the pupil has yet attained. It involves 

 close observation of any peculiarities that seem to favor the visits 

 of insects or other agents of fertilization, such as grooves, guiding 

 lines, the presence of nectar, and so on. 2 



FUCHSIA. Fuchsia coccinea, etc. 



I. Note carefully all external features, such as 



1. Position of the flower and its direction, erect or 



drooping. Compare with the flower buds. 



2. Color of different whorls. 



3. Union of parts 



a. Of the same whorl. 



b. Of different whorls.
