This very beautiful greenhouse plant is a native of Peru, from whence it has 
been recently introduced by Messrs. Veitch and Son of Exeter, through their 
collector, Mr. William Lobb, who discovered and sent the seeds, in 1 846. 
It is one of the most showy of all Polemoniaceous plants, and its habit as a 
shrub is very neat and compact ; the foliage is of the most lively green, and the 
flowers are rich in colour, and produced in the greatest profusion ; altogether, it is 
one of the most valuable of recent introductions. 
Seven or eight specimens of Cantua have been discovered and described by 
various authors, but our present subject and C. 211 /rifolia are the only two at present 
known in our collections, and both have been introduced by Messrs. Veitch through 
the same collector. 
All the kinds are tender plants, some requiring the warmth of the stove, others 
the shelter of the greenhouse. The prevailing colours of the flowers are white and 
yellow, with tinges of red in various shades and degrees ; the C. hicolor alone 
exhibits the deep rich colouring, as shown in the figure. 
The leaves and wood of all the species, but especially of the subject of our plate,
