' ties have of late become favourites with collectors ; 

 Thea^ the Tea-tree, its near relation, placed by 

 Linnaeus in Polyandria Moiiogynia^ ; Stuart ia, 

 E.vot. Bot. t. 110; and Barringtonia, the original 

 Commersonia, Sonnemt Voy. a la Nouv. Guince, 

 t. 8, 9. 



Class 17. Diadelpkia. Stamens united by their 

 filaments into two parcels, both sometimes cohering 

 at the base. Orders 4, distinguished by the number 

 of their Stamens. Flowers almost universally papi- 

 lionaceous. 



1. Pentandria. The only genus in this Order is 

 Moimieria, Lamarck t. 596, a rare little South 

 American plant, whose natural order is uncertain. 

 It has a ringent corolla, ternate leaves, a simple 

 bristly pubescence, and is besprinkled with resinous 

 dots. 



2. Hexandria, Saraca, in this Order, is as little 

 known as the Monnieria, except that it undoubtedly 

 belongs to the leguminous family. It seems most 

 allied to Browneay Jonesia, Jfzdia, &c. Fumaria, 

 the only genus besides, is remarkable for the great 

 variety of forms in its seed-vessel, whence botanists 

 who make genera from technical characters, without 

 regard to natural principles, have injudiciously sub- 



* The observations of Dr. Kendrick, of Vv'arrington, have determined 

 the class of this interesting plant, much to onr satisfaction.
