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. “ Barbatus, flowers fascicled,” (bundled together ;) it 
cannot be this species, because the flowers are not fascicled. 
62. “ Caryophyllus, flowers solitary, scales of the calyx 
eub-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, 
Diantaus caryophyllus. 
It belongs to, 
Class 10. Decanpria. Order 2. Digynia. 
64. Having analyzed a flower, you must now take one of the 
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, should 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 diffi

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 barbatus ?
