Catysteci# species. R. Brown. W.H. 
Our specimen flowered in July, at Spofforth, where it was 
sent two or three years ago, by Mr. Coorrr, botanic gar- 
dener to Lorp Mitron, who raised it from seed, received, 
we believe, from Dr. Fiscuer. ‘To Mr. ‘Coorer, who isa 
most zealous and intelligent cultivator, we were indebted 
also for the introduction of Ipomeea Platensis, of which he 
gathered the seed on the banks of the Plata, where, though 
a twiner, it acquired, by intertwisting itself, the form and 
appearance of a bush, in a country where not a tree or a 
bush was to be seen. C. dahuricus belongs to the same 
division of the genus as C. sepium, having besides the five 
segments of the calyx, two broad calyx-like bractes, which 
cover the calyx. It differs from C. sepium in having 
the bractes proportionately broader and less acuminate, a 
smaller rose-coloured flower, downy stalk, petioles, and pe- 
duncles, the leaves downy on the margin and on the nerves. 
underneath, more oblong, not so taper at the point, nor so 
broad and auriculate at the shoulder. :
