CHAPTER IV. 
Introduction to Practical Botany continued—Latin and 
Greek. Numerals— Classes of Linneus. 
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 bring many new 
thoughts to your mind; and this furnishes great encourage- 
ment for you to study; since you not only gain the knowledge 
which is the immediate object of your search, but are enrich- 
ing your minds with many connected ideas which follow 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. Linneus 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 off the petals of a rose and you will perceive the 
stamens to be inserted upon the calyx; for this reason it is of 
the 11th 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 Rosa 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 
unfer respecting the class and order of the lily ? 
70. What should encourage you to learn 2 I 
71. Are all flowers classed by the number of stamens? 
72. Are the stamens of all plants placed in the same position ? 
73. Why is the rose in the 11th class, 13th order 2
