MONOECIA. 473 



J proceed to give some illustrations of 

 the Orders in Monoccia. 



1. Monandria. Zannichellia, Mill. Illiistr. 

 t. Ti,^nd Aegopricon, Plant. Ic. ex Herb. 

 Z'inn. t. 42, are genuine examples of this 

 Class and Order, having a different struc- 

 ture in the accessory parts of their barren 

 and fertile flowers. Ai^iocarpus, the ce- 

 lebrated Bread-fruit, may likewise be 

 esteemed so on account of a partial calyx 

 in the barren flowers. The other amenta- 

 ceous genera may most intelligibly perhaps 

 be referred to the Order Fo/ijandria, 

 Cliara is now removed to the first Class in 

 the System ; see Engl. Bot, t, 336". 



2. Diandria. Anguria can remain here only 

 till the proposed reformation takes place, 

 having no difference of structure in its 

 flowers. Lemna, so imperfectly known 

 when Linneeus wrote, is now well under- 

 stood, and, having frequently united 

 flowers, belongs to the second Class ; see 

 Engl. BoL t. 926, 3095, V233.
