from the stem, are the cauline or stem-leaves, 

 generally simpler than those that spring di- 

 rectly from the root. Higher still are the 

 flowers, and on examining one of these you will 

 find five little green leaves called sepals (col- 

 lectively the calyx), and five large golden 

 petals (collectively the corolla). Within this 

 corolla are clusters of golden threads called 

 stamens, and in the center a number of green- 

 ish-yellow carpels (collectively the pistil), each 

 containing the seed of a future plant. 



EXERCISE II. 



After carefully examining the plants, make 

 a drawing of one in your Nature Note-book, 

 which should be bound in cloth and of exercise- 

 book shape. Never mind how badly you draw 

 or how humble the result draw the plant and 

 mark its parts from memory exactly as they 

 are noted in Plate II. Shade the sepals to dis-

 dicate the coloring of the whole plant with col- 

 ored chalks. The drawing is intended to be 

 more a diagram than a picture, so that the 

 plant should be posed to show structural de-
