4. Family cannaceae Order zingiberales Musaceae (bananas) Zingeberaceae (ginger,turmeric) Cannaceae (queensland arrow root)

5. Distribution It includes a single genus called Canna and 55 species . Family is tropical and sub-tropical ,native to West Indies and Central America . Flowering period: J une to October C. iridiflora ,C.indica ,C.coccinea,C.flacida ,and C.glauca all are from America . Several species are cultivated for their beautiful flowers . Canna indica (indian shot;verna-Keli ) is commonly grown in parks and gardens in our country and cultivated throughout the warmer parts of world.

6. It is represented by a single cultivated specie in Pakistan. Canna indica Linn. Common name: Indian shot ,African arrowroot, Canna lilly

7. Diagnostic feature Swollen underground tuberous rhizome Pinnate leaves Large and bisexual flower Single petaloid style usually longer than staminal tube

8. Vegetative characters Habitat: The species of Canna are perennial herbs.It perenating by means of sympodial rhizome. Root : Adventitious ,arise from rhizome. Stem : Underground sympodial rhizome Bears scale leaves .Extensively branched and grows upto 5 feet or more.

9. The rhizome of C . edulis (Achira ) (Argentina ,west indies,Australia) are tuberous,fleshy and are eaten like potatoes and yield queensland arrowroot. Leaf: Sessile , exstipulate. eligulate , alternate,entire margin , large ,elliptical or oblong shape ,apex acute,parallel unicostate vennation,pinnately veined leaves

10. Floral characters Inflorescence: Racemose: racemes, paniculate ;spicate ,forming a spike. Flower: B racteates,bracteolate, shortly pedicellate or sessile,complete, hermaphrodite, zygomorphic ,asymmetrical ,epigynous ,cyclic ,showy ,trimerous , large ,coloured. Perianth : The perianth consists of two trimerous series,the outer consist of sepals and inner of petals. The sepals are three free ,small , herbaceous ,greenish purple , persistent ,superior,imbricate aestivation

11. The petals are three united into a tube below ,larger than sepals, green or coloured, subequal imbricate aestivation. Androecium :usually 5 stamens in two whorls,out of these only one is fertile ,one form labellum,remaining three are petaloid.In some species only labellum is present in addition to fertile stamen . In some other species only two staminodes of outer whorl are coloured in addition to labellum and fertile stamen .The stamens are free and not epipetalous. Gynoecium :tricarpellary,syncarpous,trilocular , ovary inferior, axile placentation, many ovules in each loculus;ovules arranged in two rows.ovary green,warty,style one long and petaloid,flat or cup shaped,stigma one and flattened.

12. Canna stamen and ovary

13. Fruit :Usually warty capsule ;dehiscence loculicidal;capped with three persistent calyx lobes Seed: Endospermic with little endosperm and abundant perisperm. Pollination: By means of insects .

16. List of canna species Canna indica Canna discolour Canna gluaca Canna coccinea Canna paniculata Canna iridiflora Canna compacta Canna patens Jaegeriana Canna ambilis Canna liliflora Canna pedunculata Canna speciosa Canna bangii

17. Economic importance Source of starch Canna edulis is a sp of considerable economic importance as rhizomatous tubers are source of starch ,known as purple or queensland arrowroot. I t is grown as food crop in the Pacific, A sia and A ustrailia , Emergency food The rhizome of some other species such as C . bidenta are sometime used as emergency foods Medicinal use C. gigantea and C .speciosa yield extact with medicinal properties .The roots of C anna indica are diuretic and given in fever.

18. Ornamental purpose C.indic a has great ornamental value. Source of vegetable Tuberous rhizomes of C anna indica are used as vegetables. Source of fodder Canna achira and Canna edulis used as fodder
