CfcASS ICOSANDRIA. 113 



likewise to the same natural family, but extremely 

 remarkable for its distinctly-clawed, dilated, and very 

 undulated or ruffle-like fine petals. 



Nearly allied to Lythrum is Cuphea, differing 

 by its ventricose calyx ; which, at length, with the 1- 

 celled capsule, bursts longitudinally, and exposes upon 

 a toothed receptacle, the large lenticular seeds. The 

 petals, 6 in number, are also unequal, and attached or 

 inserted on the calyx. The only species in the Unit- 

 ed States is C. viscosissima, being viscid ; having op- 

 posite, petiolate, ovate, oblong leaves ; lateral, solitary 

 flowers on short peduncles, furnished with 12 stamens. 

 In certain places, and by way sides, it is rather a com- 

 mon plant from Pennsylvania southward, and bears 

 its purple flowers about September, after which it 

 perishes, being only annual. 



The next order is very properly termed Di-Pen- 

 tagynia, there being, as in Crataegus, species in the 

 same genus with 1 or 2, to 5 styles. The -Cratagus, 

 or Hawthorn, which needs no description but that of 

 the genus, has a superior, 5-cleft calyx ; 5 petals ; and 

 a closed pulpy fruit, resembling a berry, with from 2 

 to 5, 1-seeded nuts. This genus belongs also to the 

 Rosacea, and is allied to the Sorbiis, or Mountain 

 Ash, which has also a 5-cleft calyx ; 5 petals ; 2 or 

 3 styles, and an inferior or crowned berry, with a 

 farinaceous pulp, including 3 cartilaginous seeds, like 

 the pippins of the Apple. These are small trees grow- 

 ing in mountain bogs, having pinnated leaves like Ash, 

 and clustered scarlet berries, which add greatly to the 

 autumnal ornament of the forest and pleasure ground. 



The Agrimonia (Agrimony) is another genus of the 

 Rosaceje. They are herbs with some fragrance, hav- 

 ing simple or undivided herbaceous stems, clothed with 

 hairy interruptedly pinnated leaves ; and terminating in 

 slender spikes of small golden yellow flowers of 5 pe-
