OTHER SPECIES OF VIOLA. 
These are very numerous, but only a few are seen in British gardens. 
V. MONTANA, Lin.; Bot. Mag. t. 1595. 
A most beautiful species, with pale blue flowers, which are of a much larger size than those of most of the 
other kinds of violet. The plant is also much larger, the stem frequently growing a foot and a half high, or more. 
It is a native of Switzerland, and other mountainous parts of Europe; and it was introduced in 1683. It is 
quite hardy, but it is generally propagated by dividing the roots, as only a few flowers in the upper part of the 
plant, which are generally without petals, produce any seeds. 
V. CANADENSIS, Lin. ,- Swt. Brit. Flaw. Gard. 2d ser. t. 62. 
This is one of the most beautiful of all the violets. Several stems rise from the same root, all with broadly 
cordate leaves. The flowers, which are sweet-scented, are very pretty, having, when grown in pots in peat soil, 
white petals which are of a beautiful blue at the back. This has a very pretty efiisct at a little distance, as the 
flowers appear of a bright blue and clear white. When grown in the open border and in common soil, the backs 
of the petals become nearly white. The species is a native of Canada, whence it was introduced in 1783. The 
plants are propagated by division of the root. 
V. PR^MORSA, Doug. Bot. Reg. t. 1254. 
A plant with very singular flowers, which have widely-spreading, narrow, bright yellow petals, very unlike 
those of most of the other species. It is a native of California, whence seeds of it were sent home by Douglas 
in 1827. It is quite hardy, and grows "readily among rock work on the north side of large stones.*" 
V. PERSICIFOLIA, Roth. 
This species, which is a native of Germany, introduced in 1683, is very nearly allied to V. montana, from 
which it differs only in the leaves. 
V. RVV?ll,AlL; Lodd. Bot. Cab. t 686. 
A native of the Alps ; introduced in 1822, with pale blue, or white flowers. 
V. BIFLORA, Lin. 
A native of Europe, Asia, and the west coast of North America. The flowers are yellow but very small. 
V. LACTEA, AND V. HIRTA, Lin. 
These are two British species, with very pretty flowers. 
V. NUMMULARIFOLIA, All. 
A native of the rocks in the Alps of Piedmont and Dauphiny, introduced in 1820. The flowers are blue, 
with darker stripes, and the leaves are roundish. V. alpina is very nearly allied to this species. 
V. CORNUTA, Lin., Bot. Mag. t. 791. 
A native of Switzerland and the Pyrenees, introduced in 1776. A tufted plant, with pale blue flowers. 
There are many other species, but those above described are most easily to be procured in British nurseries.
