ANALYSIS OP THE PINK. 



.9 



Rose family contains many different species ; as Rosa alba, the white 

 rose, Bosa damascena, the damask rose, &c. The specific or mdi- 

 vidual name in Botany, is placed after the family name, as Bosa 

 alba, which is rose white, instead of white rose : this circumstance is 

 probably owing to the use of Latin terms ; as in that language the 

 adjective is generally placed after the noun, instead of before it, as 

 in EngUsh. 



LECTURE III. 



METHOD OF ANALYZING PLANTS. — ANALYSIS OF THE PINK, LILY, ROSE, AND 

 POPPY. 



When you begin to analyze plants, you will meet with many new 

 terms. It will be necessary in these cases, to resort to the vocabu- 

 lary of botanical words ;* by the observation of plants, connected 

 with definitions, you will soon become famiUar with the technical 

 terms of Botany. 



We will now proceed to analyze a flower in order to ascertain its 

 botanical name. We will commence with the Pink, as you are pro- 

 vided with a drawing which you can examine if you have no natural 

 flower.f 



Analysis of the Pink. 



The first step, is to 

 find the class. We will 

 suppose this flower to 

 belong to one of the Jirsi 

 ten classes ; in this case, 

 all you have to do is, to 

 ascertain the number of 

 stamens, as by this cir- 

 cumstance, these classes 

 are arranged. 



Because there are ten 

 stamens, (Fig. 4. a,) the 

 Pink is in the 10th class, 

 the name of which is, 

 Decandria. The second 

 step is to find the order. 

 In the first 12 classes, 



the orders depend on the number of pistils ;— these you must count; 



— because you find t^co, (Fig. 4. 6,) you know your flower belongs to 



the 2d order ; — the name of which is Digynia. 

 You must now turn to the " Description of the Genera of plants ;"| 



find class 10th, order 2d. The third step is to ascertain the genus of 



your plant ; for this purpose, you must compare it with each genits. 



until you find it described. 



* This is placed in the latter part of this volume. 



t In analyzing a natural flower, it is necessary to separate the parts; first, if there 

 IS a calyx, remove it carefully, then take off the corolla, or if it is rnonopetalous, cut it 

 open with a knife. A microscope is necessary if the organs are very small.
