Taxonomic Classification Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Subclass: Asteridae Order: Solanales Family: Solanaceae Genus: Capsicum Species: C.annuum Many botanical species and varieties have been raised within the genus Capsicum, and therefore, the classification is very confused. However, many authors recognize two main species; C.annuum and C.frutescens as follows. Usually annual, fruits borne singly ……………………..C.annuum Usually perennial, fruits borne in groups……………….C.frutescens  There are many cultivars, based on the differences of shape and colour of fruits. Var. abbreviatum: fruits: ovate, wrinkled, 5cm or less Var. accuminatum: fruits: linear-oblong, pointed & pungent, over 9cm Var. cerasiforme: fruits: globosely, 1-2.5cm diameter, red, yellow or purple, pungent Var. conoides: fruits: erect, conical, 3cm, very pungent Var. fasciculatum: fruits: clustered, erect, slender, 7.5cm, very p...

Taxonomic classification Kingdom: Plantae Division: Magnoliophyta Class: Liliopsida Order: Poales Family: Poaceae Genus: Saccharum Species: S.officinarum Saccharum consists of six species of perennial grasses. Two are wild species and four are cultigens. The cultivated species cannot survive for a long period in the wild state. S.officinarum is a tall perennial grass with stout, jointed, fibrous stalks that is rich in sugar. Morphological characters Stem: The stem is solid and also known as the ‘cane’ or ‘culm’. The cane is a series of joints, both above and below ground. Each joint consists of a node and inter node , with a vegetative bud at the node, a band of root primordial and above this a narrow meristematic zone or a growth ring. On the joints above ground, leaves develop, while roots and buds remain dormant. On the joints below ground,  inter nodes  are shorter and the leaves are represented by rudimentary lea...

Taxonomic classification Kingdom: Plantae Division: Magnoliophyta Class: Liliopsida Order: Poales Family: Poaceae Species: S.bicolor S. bicolor is a vigorous, annual grass with a single stem, reaching about 0.5-6m in height. Tillers are produced in some cultivars. Morphological characters Stem: The plant has a solid stem, which is usually erect. The axillary buds at lower nodes may produce tillers and higher nodes may produce branches. Root: Adventitious fibrous roots are produced from the lowest node of the stem. The stem has a band of root primordia. The root primordia that locate near the base of the plant grow out to produce prop roots. Leaves: Leaves are erect at first and later curving. The leaf arrangement is alternate in two ranks. The leaf sheath has overlapping margins that encircle the stem. Short white hairs are present near attachment to node. The Ligule is short and about 2mm long. Auricles are triangular or lanceolate. The leaf lamina is...
