In its rose-coloured flowers this forms a remarkable contrast 
to the prevalent colour of the genus to which it belongs. It 
was discovered by Hartweg near Loxa, in the Peruvian 
Andes, in a quite cool region, and was introduced by Mr. 
Linden from that region by his able collector, Mr. Wallis, in 
1865. 2A, figure of a small and poor specimen is given mm 
Mr. Bateman’s beautiful work upon this genus, and a much 
finer one in the “ Illustration Horticole,” where, however, the 
flowers are represented as larger and of a much deeper hue 
than in our plant. The specimen here figured was exhibited 
by Mr. Linden at the Horticultural Society in April, 1871.
