As to stipules — whether present or absent. 



As to the flowers — whether symmetrical or nnsymmetrical ; 

 regular or irregular j whether the calyx be free or adherent; 

 the petals, whether distinct or united; the stamens, whether

 alternate with them. 



As to the pistil and fruit, — whether the carpels be more

LESSON XXXIII. 



HOW TO ANALYZE A PLANT BY THE TABLES. 



272. Our readers are already informed that the Flora 

 which accompanies these instructions is not intended to 

 make them acquainted with the plants of the country, but 

 simply to teach the pupil how to analyze. Hence they w-ill 

 not expect to find in it any thing like a full account of all 

 our flora,' but a few plain exercises by which they may trace 

 every, flowering plant in the .country to its Natural Order, 

 about one in every two to its Genus, and about one in every 

 five to its Species. In conducting an exercise in this Floi-a 

 with a class of pjipils who have well studied the-former part 

 of the work, some method like the following would be inter- 

 esting and profitable. 



273. Suppose the class present, and each furnished with a spe- 

 cimen of some one unknown species, Taoth in flower and fruit. 



Teacher. Are you all ready? Turn tq the Flora and let us find out to- 

 gether the family relations and the names of this flrie plant. We will 

 commence at the "Analysis of the Natural Orders" (page 132), and read 

 the first pair of lines, which we will call a couplet.
