58 AN INTRODUCTION 



titles has been given in the last chapter in the expla- 

 nation of the classes, it need not be repeated here. 



CLASS XXI IL POLYGAMIA. In this class the 

 titles of the two first orders are the same with the 

 titles of the twenty-first and twenty-second classes, 

 and are to be understood in the same manner, that 

 is, 1 . Monoeda when the polygamy is on the same 

 plant, and 2. Dioecia when it is on distinct plants. 

 The order Trioecia has been established in favour of 

 two genera the Ceratonia and Ficus, in which the 

 polygamy is on three distinct plants, one producing 

 male flowers, another female, and a third herma- 

 phrodite or androgynous. 



CLASS XXIV. CUYPTOGAMIA. The orders of 

 this class are, 1 . Filices, ferns. $. Musei, mosses. 

 3. Algae^ flags*, and. 4. Fungi, mushrooms. As the 

 explanation of the character of these orders will 

 come more properly into the chapter that treats par- 

 ticularly of this class, we shall content ourselves here 

 with having interpreted the titles as above. 



CHAP. IV. 



OF THE FIRST CLASS MONANDRIA. 



THIS Class consists of such plants as bear herma- 

 phrodite flowers, furnished with but one stamen. The 

 orders are two, viz. 



ORDER I. MOXOGYNIA, comprehending such 

 plants as have but (>ne style. This order contains 

 fourteen genera, distinguished into, 1. Stitamiueae, 

 such plants as have the flowers placed above the ger- 

 inen, and the pericarpium divided into loculaments ; 

 of which there are ten, viz. Reneahnia, Canna, Amo- 

 mum, Costus, Alpinia, Maranta, Curcuma, Myrosma, 

 Kaempferia, and Thalia. 2. Monospermous, such as 

 have a single seed ; of w r hich there are four, viz. Boer- 

 haavia, Salicornia, Hippuris, and Pollichia. 



* Modern Botanists have divided this order into two, viz. 

 Hcpaticac and Algae. Soe Chap, xxvii.
