No author appears to have known this fine species of G¥no- 
thera, till Mr NutTauu discovered it on the plains of the Red — 
River, in the Arkansa territory of North America, flowering in 
the months of June and July, and afterwards described it in 
the work above quoted. 
It was in 1821 raised from seeds brought from the Arkansa, 
at the Garden of the University of Philadelphia, by Mr Drcx, 
and that gentleman was kind enough to communicate some of © 
the seeds which ripened under his care, to the Botanic Garden _ 
of Glasgow. Our plants blossomed in the greenhouse in the 
beginning of July, making a very showy appearance, and emit-. 
ting a delightful fragrance, which, like some of the other spe- 
cies of this genus, is most powerful in the evening. , The 
CH. speciosa promises to be a great acquisition to our collec- 
tions, especially if, as is very probable, it should be found ca- 
pable of bearing the open air in this climate. 
The flowers continue many days in perfection, but are most 
fully expanded at the approach of —
