1, PcntaiHh'Ui. Tlic only i;onus in this Or- 

 der is Mojiuicria, Latjiarck, t. of)6', n raro 

 little South American plant, whose n..tural 

 pnL'r is uncertam. It has a ringent co- 

 rolla, ternate leaves, a simple bristly pu- 

 bescence, and is bcsprmkled with resinous 

 dots. 



2. llexandi'ia. Sciraca^ in this Order, is as 

 little known as the Monnieria, exceot that 

 it undoubtedly belongs to the leguminous 

 family. It seems most allied to Brownea, 

 Jonesia, Jfzelia, Sec, Fumaria, tlie only 

 genus besides, is remarkable tor the great 

 variety of forms in its seed-vessel, whence 

 botanists who make genera from technical 

 characters, without regard to natural prin- 

 ciples, have injudiciously subdivided it. 

 See EugL Bot. t, 588—590,943, 1471. 



3. Octandvia. Foli/gala, t. 76'? is th.e prin- 

 cipal genus here. America and the Cape 

 of Good Hope abound in beautiful species 

 of It, and New Holland affords some new 

 genera, long confounded with this. IJal^
