DIDYNAMIA ANGIOSPEFxMlA. 



This order of the artificial system of LinniEus consists, except 

 Digitalis, of his own natural order o^ Personatce, 40, and 

 comprehends two of Jussieii's, Pediculares, 35, and Scro- 

 phularice, 40. To the former belong, more or less exactly, 

 all the British genera of our first section, characterized 

 by a four-cleft calyx ; as well as Pedicularis, whose calyx 

 is five-cleft, and Orobanchc, which has a two-lipped, or 

 two-leaved, calyx. To the ScropJmlarice belong all our 

 genera with a five-cleft calyx, except Pedicularis and Lin- 

 ncea, the latter being properly referred to Jussieu's Ca- 

 'prifolia, 58, the first section of which only really consti- 

 tutes the order so named. Tiie Pediculares and true Scro- 

 phdaricE have been nnited by Mr. Brown, Prodr. N. 

 Holl. V. 1. 433, under the appellation of Scroplndarinoe, 

 Two new orders have nevertheless been recently founded, 

 out of these, by M. Richard, the Mcdampyracece and 

 Orohanchece. I presume to think them superfluous, and 

 shall offer my reasons under the genera whose names they 

 bear. 



Mr. Brown thus defines his Scrophularince. 



Calyx divided, permanent. 



Corolla of 1 petal, inferior, mostly irregular, segments im- 

 bricated in the bud, deciduous. 



Stamens generally 4, 2 longer and 2 shorter, rarely equal : 

 sometimes but 2. 



G^n«^« with many seeds, in 2 cells; style 1; stigma 2- 

 lobed ; rarely undivided. 



Capside, (very rarely a Berry,) of 2 cells, with 2 or 4 valves, 

 which are either undivided or cloven; the partition either 

 double, originating from the inflexed margins of the 

 valves ; or simple, either parallel to the valves and undi- 

 vided, or contrary to them and separable into 2 parts. 

 Receptacles central, attached to the partition, sometimes 

 separating finally from it. 



Seeds numerous, albuminous; the Embryo internal, straight ; 

 Radicle directed towards the scar. 



Herbs, sometimes shrubs, with for the most part opposite 

 leaves. Liflorcsccnce various. Stipulas none. 



Mr. Brown justly reprehends Jussieu for making the di- 

 stinction of a parallel or transverse partition in the fruit 

 absolute, thus splitting one natural order into two. It is
