This is one of the many lovely tropical plants now cultivated 
in our stoves, distinguished by the “ folia discolora ;” that is, the 
upper and underside differmg in colour, and the upper with a 
rich and glossy surface, refracting the rays of light m such a 
manner as to give a coppery or velvety hue, not easily repre- 
sented in a drawing. he subject of our present plate was 
received at the Kew Gardens from Mr. Henderson, St. John’s 
Wood Road Nursery, under the name of Hriocnema eneum ot 
Naudin. But the plant is no Hriocnema. It belongs to the 
curious and beautiful genus Bertolonia, “ dont le caractere essen- 
tiel consiste,” as M. Naudin has himself well expressed, dans 
la forme tout-d-fait insolite du calyce et de la capsule ;” and it 
is equally certain that it is the B. maculata of De Candolle and 
of Martius above quoted, t. 257. his fruit or capsule is an 
elegant object, especially when the eye is aided by a small power 
of the microscope ; for it is singularly inflated, with three very 
prominent angles and several ribs, and every rib, as well as the 
margin of the lobes of the calyx, is beset with bristles, termi- 2
