236 FLORA'S LEXICON. 



the third, fourth, and so on, up to the tenth, are named in the 

 same way, triandria (three males), tetrandria (four males), &c. 

 &c. There being no plants with eleven stamina, and the num- 

 ber not being uniformly twelve in many plants, though there or 

 thereabouts, the eleventh class, called dodecandria (twelve 

 males), includes all plants that have from eleven to nineteen 

 inclusive. If the stamina are twenty or more, and are attached 

 to the calyx or corolla, the plants belong to the twelfth class. 

 icosandria (twenty males). If above nineteen, and attached to 

 the base of the flower, and not to the calyx or corolla, they are 

 of the class polyandria (many males), which is the thirteenth 

 class. Plants with four stamina, two of which are shorter than 

 the other two, are in the fourteenth class, didynamia (two pow- 

 ers). Plants with four long and two short stamina constitute the 

 fifteenth class, the telradynamia (four powers). In monadelphia, 

 which is the name of the sixteenth class, the threads of the sta- 

 mina are all united at bottom, but the anthers are separate. In 

 diadelphla the threads are united, not altogether, but in two 

 bodies. In polyadelphia they are connected in three or more 

 bodies. If the threads are separate, but the anthera? united, the 

 plant is in the nineteenth class, syngenesia. In all the above 

 classes the stamina are distinct, and separate from the pistil lum ; 

 but where the former grow upon the latter, the plant is of the 

 class gynandria, which is the twentieth. Sometimes the sta- 

 mina are in one blossom, and the pistillum or pistilla in another 

 but on the same plant : in this case they form the class moncecia 

 (one house). But if the staminiferous blossom is on one plant, 

 and the pistilliferous on another, it is of the twenty-second class, 

 diacia (two houses). And lastly, if some blossoms have both 

 stamina and pistilla, and others only one or the other, whether on 

 the same plant, or on different plants, they come under the 

 twenty-third class, polygamia. These include all vegetables! 

 whose flowers are conspicuous. But there are some, as mosses, 

 sea-weeds, mushrooms, &c., whose flowers are inconspicuous, or 

 whose parts of fructification are not stamina and pistilla. These 

 are all arranged together in the twenty-fourth class, called cryp- 

 togamia.
