cutting off the shoots near the root, which are inserted in hills 

 or trenches. The cuttings take root at the joints under 

 ground, and in about 12 months, become ten or twelve feet 

 high, when they are cut down for the mill. A plantation 

 lasts from six to ten years. 



ORDER III. TRIGYNIA. Stamens 4. Styles 3. 

 This order contains few plants, and none of any interest. 

 CLASS IV. TETRANDIA. Stamens 3. Orders 3. 



Fig. D. 



This class is neither so important, nor so 

 large as the last. It is composed chiefly of 

 ornamental, or curious shrubs, and is there- 

 fore interesting to the young florist. Many of 

 the most important plants of this class are 

 confined to the southern hemisphere. Among 

 the ornamental, or useful genera which are 

 generally known, are the Holly, (Ilex,) the Madder, (Rubia,) 

 the Teasel, (Dipsacus,) and the Sandal Wood, (Santalum.) 

 The Ixora, and Pavetta, are beautiful, ornamental shrubs. 

 These are. hot-house plants. In this class all the stamens are 

 of the same length ; but there is less affinity in the appear- 

 ance and qualities of the species, than in most of the other 

 classes. 



ORDER I. MONOGYNIA. Stamens 4. Style 1. 



This is a numerous order, and contains an assemblage of 

 species which have little resemblance to each other. It is 

 separated into eight divisions, founded on the absence or 

 presence of a corolla, the number of petals it contains when 

 present, its situation, whether superior or inferior, and the 

 number of seeds contained in the cells of the capsules. 



GENUS Protea. The name is derived from Proteus, the 

 son of Ocean and Thetis, who is said to have assumed vari- 

 ous forms. It is so named in allusion to the varieties of form 

 and appearance of the species of this genus. 



The genus has a calyx, which is separable into two parts. 

 Style, awl-shaped. Stigma, narrowly cylindrical. Nut, 

 bearded on all sides. The plants are deciduous shrubs, from 



How many stamens has the class Tetrandia ? Of what kind of plants 

 is this class chiefly composed ? What is said of the order Monogynia, of 

 this class?
