V. RUGOSA, D. Don, Swt. Brit. Flow. Gard., 2nd ser., t. 318. 
The flowers are dark purple, and the leaves ragged. The species is a native of Buenos Ayres, whence it 
was introduced in 1837. H is rather more tender than most of the other species of the genus, but it will flower 
well in the open air during the summer, if it be taken up in autumn, or protected in any way during the winter. 
V. VENOSA, Hook, Swt. Brit. Flow. Gard., 2nd ser., t. 207. 
This is a very robust species, with dark purple flowers, and abundance of coarse strongly-veined leaves. It 
is a free grower, and quite hardy in British gardens, though it is a native of Buenos Ayres, whence it was 
introduced about 1830. It is well adapted for covering a bed in a flower-garden, on account of the great 
rapidity of its growth.
