This property is not uncommon with plants in this 

 natural Class. The Dandelion opens at live or six in 

 the morning, and closes at nine. The Mouse-ear 

 Hawk-weed opens at eight, and closes at twelve. The 

 Sow-thistle opens at five., and closes between eleven 

 and twelve, and the Goat's-beard opens at three in 

 the morning, and closes at five or six in the morning, 

 in fine weather. 



GREAT GLOBE THISTLE blossoms in July, 

 and the seeds ripen in August. It is a native of most 

 of the countries in Europe, but not of England, and 

 was introduced into our gardens in 15^6. In its na- 

 tive state it grows in any soil or situation, but is not 

 more than two feet high; by culture it grows to more 

 than twice that height. 



Of these two last Orders there is no native English 

 plant. 



* The Botanical names of these five Orders are, 1. Polyga- 

 mia sequalis. 2. Polygamia superflua. 3. Polygamia frus- 

 tranca. 4. Polygamia necessaria. 5. Polygamia segregate*.
