Canna Gaboniensis.—A species from the Gaboon River, with the habit of C. nepalensis. Rhizomes large and round; stalks green, large; leaves deep green lightly edged with purple, longish, acuminate; flowers medium-sized, clear orange; habit fine, special; height 5½ ft. to 6 ft.
Canna gigantea.—A robust kind, growing about 6½ ft. high. Flowers in summer, large and very handsome; external divisions orange red; internal ones deep purple-red; spathes reddish. Leaves more than 2 ft. long; stalks covered with a velvety down. S. America.
Canna indica.—Flowers in summer, tolerably large, irregular, in erect spikes; external divisions light yellow; upper inner divisions of a carmine-red; the lower one yellow dotted with carmine. Leaves large, alternate, oval-lance-shaped; the stalks sheathing at the base. Stems 3 ft. to 6 ft. high. A variety (C. i. superba) has much larger flowers of a scarlet colour. India. It is not nearly so useful or imposing in appearance as some of the newer hybrid kinds.
Canna iridiflora.—Flowers in midsummer, large, lively rose-colour, with a yellow spot on the lip; divisions of the calyx red, erect, oval-acute; spikes somewhat drooping, issuing several together from the same spathe. Leaves broadly oval-acuminate, slightly membranous at the margin, and having some hairs at the lower part of the midrib. Stems 6 ft. to over 8 ft high. Peru. A somewhat tender species, and although one of the finest, does not flower freely. To secure its blooming, the plants should be taken up towards the end of summer, potted, and kept in a hothouse through the winter. They should be watered moderately, and, treated in this way, will almost always begin to show flower in the ensuing spring.
Canna limbata.—This has numerous stems nearly 3 ft. high, and oblong-lance-shaped, acute leaves. Flowers in long loose spikes issuing from glaucous spathes tinged with red; outer divisions pale yellow; upper lip scarlet edged with a yellow margin; lower lip red, with golden reticulations. Brazil.
Canna musæfolia.—This species was formerly described in the English, Dutch, and German horticultural journals under the name of C. excelsa. It was named musæfolia by M. Année, who introduced it into France in 1858, from the resemblance of its leaves to those of the Musa or banana-tree. It reaches a height of more than 8 ft., and has green, downy stems, and very large, oval, green leaves. Flowers small, orange-yellow. It is a tender species without rhizomes, and requires to be kept constantly growing. Peru.
Canna nepalensis.—A variety of C. glauca (according to M. Chaté), introduced into France by M. Wallich, director of the Botanic Garden at Calcutta. About 6½ ft. high, with oval-lance-shaped glaucous leaves, narrowed at both ends. Outer divisions of flower greenish-yellow; inner ones, sulphur-coloured or light orange.
Canna purpurea spectabilis.—Rhizomes cylindrical. Stalks medium-sized, purple. Leaves deep greenish purple, fair size. Flowers small, scarlet. Rather uncommon; habit fine; height 6 ft. to 6½ ft. This is a very hardy species, and has given rise to all the varieties with red or striped leaves.
Canna Warscewiczii.—A very early-flowering species, easily raised from seed, and if sown early in spring, may be used for decorative purposes the same year. Stems numerous, reaching a height of somewhat over 3 ft. Leaves oval-elliptical, narrowed at both ends, and deeply tinged with dark purple. Flowers with brilliant scarlet inner divisions; outer ones purplish. S. America. There are many handsome varieties of this species in cultivation.
Canna Alfred Dumesnil.—Rhizomes clouded, elongated. Stalks medium thickness, deep greenish-purple. Leaves medium-sized, acuminate and erect, deep green striped with violet-purple. Flowers large, well-formed, scarlet. Free-flowering; height 3½ ft. to 4 ft.
