120 NEW SPECIES OF PLANTS. 



This very beautiful and ornamental species, opens 

 towards evening, and endures nearly throughout the 

 day ; the period of inflorescence is, however, remark- 

 ably evanescent compared with that of the rest of the 

 genus, but it is a perennial of easy propagation. 

 # Cultivated Locality. — The garden of the Univer 

 sity of Pennsylvania. 



8. (Enothera Hinifolia, foliis integris, radicalibus 

 lanceolatis, caulinis linearibus confertis ; racemo nu- 

 do terminali ; capsulis obovatis angulatis pubescen- 

 tibus; petalibus obcordatis staminibus longioribus : 

 stigma quadrilobo. 



Habitat. On the summits of arid hills and the 

 shelvings of rocks, near the banks of the Arkansa. 

 — Flowering from May to July. 



Observations. A remarkably small and bien- 

 nial species, somewhat allied to CE. pusilla of Mi 

 chaux. The whole plant, except the capsule, is com- 

 monly smooth, the radical and stem leaves are very 

 dissimilar in appearance, the flowers scarcely two 

 lines broad, and yellow ; the bractes of the raceme 

 are ovate, the seeds very small, and the valves rff 

 the capsule, as is usual in this section of the genus, 

 •pen by partial involution from the summit. 



9. (Enothera sermlata, foliis linearibus spinu- 

 loso-serratis acutis ; floribus axillaribus ; calyces 

 foliolis carinatis ; stigma quidrilobo ; capsulis cylin- 

 dricis erectis ; caule suffruticosa.
