ANALYSIS OF THE ROSE. 25 



to compare each genus with your flower, till you find a descrip- 

 tion which corresponds with the Lily. 



" HEMEROCALLIS. "Corolla six parted." Six parted shows 

 that the corolla is all of one piece, having divisions around the 

 border. The Lily is not six parted, but has six petals, there- 

 fore you need look no farther in this genus. 



" LILIUM." Now compare each particular in this description 

 with your flower, (looking out; the terms in the vocabulary,) and 

 you will find an agreement in every respect. 



In the description of a genus, nothing is said about any part 

 of the plant, except the different organs which compose the 

 flower; in the species, the distinctions are chiefly drawn from 

 different circumstances of the leaves, stems, <fyc. 



The flowers of two plants may agree so as to belong to the 

 same genus,, while the leaves, stalks, and branches are very 

 unlike, and the plants are therefore considered as belonging to 

 different species. 



Thus in the genus Lilium, the shape of the leaves, the man- 

 ner in which they grow on the stem, the height of the stem, the 

 number of flowers growing upon the stem, the manner in which 

 they grow whether erect or nodding, and the shape of the co- 

 rolla; all these, and some other circumstances, distinguish 

 the 1 different species. The colour, a quality of the flower 

 usually the most striking, is, in botany, little regarded, while 

 many other circumstances, which might at first have been 

 scarcely noticed, are considered as important. 



In the llth class, Icosandria, and the 12th class, Polyandria, 

 we are to remark, not only the number of stamens, which is 

 always more than ten ; but the manner in which they are inserted, 

 or the part of the flower on which they are situated. If in pull- 

 ing off the corolla, the stamens remain upon the calyx, the 

 plant belongs to the 1 1th class ; but if the corolla and calyx 

 may be both removed, and the stamens still remain on the re- 

 ceptacle, the plant is of the 12th class. 



It is .said that no poisonous plant has the stamens growing on 

 the calyx ; it is in the 1 1th class that we find many of our most 

 delicious fruits, as the Apple, Pear, &c. 



Analysis of the Rose. 



The rose, on account of its beauty, is one of the most con- 

 spicuous flowers in the 1 1th class ; it is considered as one of the 

 most interesting of the vegetable race, and is often dignified 

 with the title of " queen of flowers."
