Ch. IV.] INTRODUCTION TO PRACTICAL BOTANY CONTINUED. 23 



CHAPTER IV. 



Introduction to Practical Botany continued Latin and 

 Greek Numerals Classes of Linnccus. 



69. You have been taught to analyze one flower ; while 

 you were doing this, did not many thoughts seem of themselves 

 to come into your minds ? You examined a lily ; you found it 

 had six stamens, and one pistil, and it is very likely you 

 thought that if the pink was in the tenth class and second order 

 because it had ten stamens and two pistils, the lily must be in 

 the sixth class and jirst order it is so. 



70. Now when you learn one fact it will biing many new 

 thoughts to your mind; and this furnishes. . great encourage- 

 ment for you to study; since you not only gain the knowledge 

 tvhich is the immediate object of your search, but are enrich- 

 ing your minds with many connected ideas which folloAv in its 

 train. 



71. You will, perhaps, now think that all flowers are classed 

 by' the number of stamens, but this is not correct, for as some 

 have more than a hundred stamens, such an arrangement would 

 be making quite too many classes ; and besides, it is found 

 that such plants as have more than ten, often vary in the num- 

 ber of stamens, so that only the first ten classes depend on this 

 circumstance. 



72. Linnaeus discovered that the stamens of some plants 

 grew upon the calyx, and others upon the receptacle; the rose 

 is of the former kind, and the poppy of the latter. 



73. Take oft' the petals of a rose and you will perceive the 

 stamens to be inserted upon the calyx ; for this reason it is of 

 the llth class ;. and because it has many pistils is in the 13th 

 order. 



74. The name of the genus is Rosa. In this genus are many 

 species ; as R,osa muscosa, or the moss rose, which has upon 

 its calyx and stems a collection of hairs resembling moss 

 Rosa alba, the white rose, distinguished not only by the white- 

 ness of its petals, but by peculiar circumstances of the leaves 

 and stems. 



69. After learning the classification of the pink, what should you 

 aifer respecting the class and order of the lily 1 



70. What should encourage you to learn? 



71. Are all flowers classed by the number of stamens ? 



72. Are the stamens of all plants placed in the same position 7 



73. Why is the rose in the llth class, 13th order 7 ? 



""4. What is observed of the different species in the genus rosa 7
