Mod of the Evening-Primroses grow in a rambling un- 

 fightly manner, to which the CEnothera glauca makes a 

 happy exception, the (terns being only about a foot high, fimplc, 

 and growing many together. They are well clothed with fine 

 glaucous -green oval leaves, not very unlike thofe of Androfae- 

 mum, though fmaller. The flowers are large and fhewy, and 

 have the unufual advantage of remaining open by day, as well 

 as by night, unlefs expofed to a hot fun. So that altogether, 

 this is one of the mod defirable of the whole genus. 



It has, we believe, been never before figuredj nor does it occur 

 in the new edition of the Hortus Kewenfis. 



Native of the molt weftern parts of North-America towards 

 the country of the Illinois, near the Miflifippi. Seems to be 

 perfectly hardy, and may, we fuppofe, be eafily propagated by 

 parting its roots, if it mould not produce ripe feeds. Introduced 

 by Mr. Lyons. Our drawing was made from a plant com- 

 municated by MefTrs. Dungate and Wooster, Nurferymen, 

 at Brixton. It is alfo an inhabitant of the Botanic Garden, 

 Sloane- Street.
