HERBACEOUS PLANTS. 

 XLIII. (Enothera speciosa. Nuttall. 

 A handsome perennial plant, lately discovered in the Ar- 

 kansa country, in North America. As a border plant it is 

 recommended by the beauty and long succession of its flowers, 

 but its creeping roots, which over-run the neighbourhood of 

 the spot where it is planted, render it objectionable. Its 

 stem is downy, about two feet high, covered with glaucous, 

 cut, lyrate leaves. The flowers are large, white, very hand- 

 some, becoming pink upon closing. The anthers and stigma 

 are pale yellow, the latter four-lobed, a little dashed with red. 

 The capsule is erect, short, rounded, truncate, with eight 

 prominent ribs, which are alternately narrower. Roots were 

 brought to the Society from North America, by Mr. David 

 Douglas, in 1824. It is figured in Dr. Hooker's Exotic 

 Flora, tab. 80, and is propagated with facility by divisions of 

 the roots. 



XLIV. (Enothera triloba. Nuttall. 



Seeds of this interesting species of (Enothera were brought 

 from North America by Mr. David Douglas, in the spring 

 of 1824. It is a stemless spreading annual plant, with closely 

 tufted bright green leaves, which are deeply lyrate, and quite 

 smooth. The flowers are bright yellow, seated among the 

 leaves, and expanding in the evening only. Stigma four- 

 lobed ; capsules smooth, sessile, very short, with four trian- 

 gular angles, and four horns at the end between the angles, 

 i he species has much resemblance to the (Enothera acaulis, 

 noticed in the Report of last year, but is distinguished from it
