"Canna indica" (also known as saka siri, Indian shot, canna, bandera, chancle, coyol, or platanillo) is a species of the Canna genus, belonging to the family Cannaceae, a native of the Caribbean and tropical Americas that is also widely cultivated as a garden plant. It is a perennial growing from 0.5m to 2.5m, depending on the variety. It is hardy to zone 10 and is frost tender. In the northern latitudes it is in flower from August to October, and the seeds ripen in October. The flowers are hermaphrodite. [Johnson's Gardeners Dictionary, 1856] Chaté, E.

The seeds are small, globular, black pellets, hard and heavy enough to sink in water. They resemble shotgun pellets giving rise to the plant's common name of Indian Shot. They are widely used for jewellery. The seeds are also used as the mobile elements of the kayamb, a musical instrument from Réunion, as well as the hosho, a gourd rattle from Zimbabwe, where the seeds are known as "hota" seeds.

Taxonomy

In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Paulus Johannes Maria Maas from the Netherlands and Nobuyuki Tanaka from Japan. Maas regards "C". "coccinea", "C". "compacta", "C". "discolor", "C". "patens" and "C". "speciosa" as synonyms or varieties of "C". "indica", while Tanaka recognises several additional varieties of "C". "indica".

*"Canna indica" var. "indica" L.:A medium sized species; green foliage, oblong shaped, spreading habit; triangular stems, coloured green; spikes of flowers are erect, self-coloured red, staminodes are long and narrow, edges regular, petals red, partial self-cleaning; fertile both ways, self-pollinating and also true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured purple; tillering is prolific. Introduced by L.Tanaka, N. 2001. Taxonomic revision of the family Cannaceae in the New World and Asia. Makinoa ser. 2, 1:34–43.]
*"Canna indica" var. "flava" (Roscoe ex Baker) Nb. Tanaka:Yellow bloom. Many plants previously offered as C. lutea fall into this sub-species.
*"Canna indica" var. "maculata" (Hook) Nb. Tanaka:A medium sized species; green foliage, ovoid shaped, branching habit; spikes of flowers are erect, yellow with red spots, staminodes are long and narrow, edges regular, petals green, fully self-cleaning, low bloomer; fertile both ways, self-pollinating and also true to type, capsules globose; rhizomes are thick, up to 3 cm in diameter, coloured white and pink; tillering is average. Introduced by Hook.. Many plants previously offered as "Canna lutea" fall into this sub-species.
*"Canna indica" var. "sanctae rosea" (Kraenzl) Nb. Tanaka:A small species; green foliage, oval shaped, white margin, branching habit; spikes of flowers are erect, self-coloured pink, staminodes are long and narrow, edges regular, labellum is pink, stamen is pink, style is pink, petals red with farina, fully self-cleaning; fertile both ways, self-pollinating and also true to type, capsules ellipsoid; rhizomes are thick, up to 3 cm in diameter, coloured white and pink; tillering is prolific.
*"Canna indica var. warszewiczii" (A.Dietr.) Nb.Tanaka:This variety is distinguishable from "C. indica" var. "indica" by having purple-red-margined leaves, purple-red fruits and slightly corm-like thickened terrestial stem at the base. Additionally to this, there are normally two staminodes , recurved backwards, and the stamen is often strongly reflexed at the apex. These characteristics are fairly stable in this taxon. Sometimes, this variety is confused with C. "discolor" Lindl., from which it differs in much smaller, deep-red coloured flowers, short and slender rhizomes and chromosone numbers (2n=27 in C. "discolor" and 2n=18 in C. "indica" var. "warszewiczii")
