Specimens of this charming annual, rivalling the Bartonia 
aurea (from which no doubt it derives its specific name), were 
obligingly communicated to us, through Mr. G. Charlwood, of 
Covent Garden, by Mr. Booth of the Floetbeck Nursery, Ham- 
burg, under the name of Ewenida bartonioides, accompanied by 
a very faithful description. It bears the open air like the Bar- 
tonia, is admirably suited for a border plant, and we trust that 
seeds of it will soon be, if they are not already, in the market. 
Dr. Walpers had perceived the close affinity of this with another 
plant, our Microsperma lobata, given in the ‘Icones Plantarum 
Rar.,’ IIT. tab. 234, and he very properly united it with that genus, 
of which it is nevertheless a very distinct and far more beautiful 
and showy species. It flowers through the summer months. 
Dzscr. An herbaceous annual. Stems about a foot long, 
flexuose, succulent, subtranslucent, hispid. eaves hispido- 
pubescent, on longish slender petioles, ovate, acute, lobed and 
serrated. Peduncles elongated, single-flowered, terminating the 
JANUARY Ist, 1850.
