CJl. II1.J HERBARIUM. *1 



58. You have a fourth step to go in the analysis of this flow- 

 er ; for each genus is composed of several sorts or species of 

 plants. It is necessary to know to what species of the genus 

 Dianthus this flower belongs. 



59. Look in the latter part of your book for the " Description 

 of species of plants."* Here you find the genera arranged in 

 alphabetical order, each genus being followed by a description 

 of its species. If you have a natural flower with its leaves, 

 you can now compare it with the specific descriptions. 



60. " Armeria, flowers aggregate ;" this means clustered 

 together on one stalk; but pinks do not grow in this manner 

 therefore the plant is not of this species. 



61. li Barbatus, flowers fascicled," (bundled together;) it 

 cannot be this species, because the flowers are noi fascicled. 



62. " Caryophyllus, flowers solitary, scales of the calyx 

 sub-rhomboid ;" (sub-rhomboid means somewhat diamond 

 shaped,) " very short, petals crenate" (scolloped on the edge,) 

 beardless, (without hair or down.) The pink is in all respects 

 answerable to this description. It is also added, that the leaves 

 are " linear," which means long and narrow ; " subulate" sig 

 nifies pointed at the end like a shoe-maker's awl ; channelled^ 

 signifies having a groove or channel running through the leaf. 



63. You have now learned the class and order of the pink, 

 with the genus and species to which it belongs. The botani- 

 cal name of the pink is, 



DIANTHUS caryophyllus. 

 It belongs to, 



Class 10. DECANDRIA. Order 2. DIGYNIA. 



64. Having analyzed a flower, you must now take one of tne 

 same kind, and lay it between sheets of paper to dry, having a 

 weight placed over to press it. Every person who would be- 

 come a Botanist, shouiJ preserve specimens of all the plants 

 he meets with. A book of such specimens is called an herb- 

 arium. 



65. There are few parents who would not delight to see a 

 handsome herbarium made by their child. There is no dim-

59. Where are you to look to find the species! 



60. Why is not the pink of the species armeria? 



61. Why is it not of the species btirbatus ? 



62. Why is it not of the species caryophyllus ?
