S. eaueasieinn is distinguished from the other blue-flowered species by the 
softly hairy stem and leaves, by the lower leaves, especially the radical ones, 
being gradually attenuated into the petiole, and by the tubular shortly toothed 
calyx. The leaves vary from broadly ovate, as in the Cartalina and Chelsea 
Garden plants, and in the figure t. 3188 of the * Botanical Magazine,’ to 
oblong-lanceolate, as in the Nosdoe and Georgia plants, and in those collected 
in Oxfordshire by Mr. С. C. Druce. Some autumnal radical leaves of the 
Chelsea Garden plant which flowered at Clifton in 1912, attained a large 
size (6 dem. x 1°5 dem.) with the blade of the leaf gradually attenuated 
nearly to the base of the petiole. The leaves are wrinkled and repand, as 
shown in t. 294 of the * British Flower Garden.’ The flowers are generally 
as described in the * Botanical Magazine,’ “red-purple then a lively azure,” 
but in the Chelsea plant they were very pale blue, and of the same colour 
when the plant flowered at Clifton in the succeeding year, during several 
months of variable weather. This plant was completely sterile. 
S. caucasicum appears to have been first introduced into Britain in 1830, 
when Dr. Fischer sent seeds from St. Petersburg to Edinburgh; the plants 
which sprung from these flowered in 1832. Seeds were also received at 
Chelsea from Dr. Fischer, probably at the same time, as Don's figure in the 
‘British Flower Garden’ was taken from the resulting plants in 1835.
