FLAME OF THE FOREST Scientific Name: Butea monosperma FLAME OF THE FOREST Originated from Madagascar Discovered by botanist Wenzel Bojer in 1820 Description: Flowers grow in dense clusters Flame-coloured and faintly scented Fruits are long pods, dangling down sword-like FLAME OF THE FOREST Animal Pollination: Birds Petals brightly coloured Nectar Funnel-shaped to enable the bird to sip the nectar Stigma sticky Capable of self and cross pollination FLAME OF THE FOREST Uses: Planted as an ornamental tree in parks, gardens and along roads as they are spectacular and beautiful when in full bloom Broad umbrella-shaped crown makes it a good shade tree Bark can be used as a cooling drink to prevent fevers MODE OF POLLINATION • Insect-Pollinated FEATURES Large, brightly coloured petals Small stigmas that does not protrude out of flower Scented EXPLANATION Most fragrant in the evening to attract the moths, which come in search for nectar. But the flower has no nectar. So the moths would unintentionally pollinate the flower while trying to search for the nectar. MODE OF POLLINATION Insect/Animal Pollinated Pollinated by butterflies, but mostly by hummingbirds FEATURES Large, brightly coloured petals Nectar present EXPLANATION The birds hover at the bloom, draw nectar with their long and slender bills, and transfer pollen by coating themselves with it via their flapping wings. MORNING GLORY Scientific name: Ipomoea indica Mode of pollination: Insect MORNING GLORY Common Insect-Pollinated Flower Large, brightly coloured petals Nectar present May be scented Small stigmas that does not protrude out of the flower Stamens are not pendulous and does not protrude out of flower Pollen are fairly abundant, large with rough surfaces Nectar guides may be present on the petals Ipomoea indica P P O P P P P MORNING GLORY The Morning Glory opens in the morning and closes at night. WHY? In the daytime, it is more likely that insect pollinators would be visiting the flowers. At night it is less likely that these insect pollinators will come. Through natural selection, the plant has learnt that opening in the morning is more ‘successful’ than opening at night. Therefore over time, the plant has evolved with this feature. MORNING GLORY Morning Glory has creeping stems. This can potentially cause a serious weed problem. Morning Glory seedpods MODE OF POLLINATION • Pollinated by insects • Such as bees ADAPTATION FOR POLLINATION • Although mode of pollination is by insects, its flowers are small and has no fragrance • This is compensated by the plant transforming the buds near them to resemble blossoms. These have colorful petals and attract the bees. PICTURES MODE OF POLLINATION • Pollinated by animals • Birds (Hummingbird) • Insects (Butterfly) ADAPTATION FOR POLLINATION • • • • Produced in clusters Has long floral tubes Brightly colored Produces hard, fleshy berries PICTURES DANDELION Scientific Name: Taraxacum officinale DANDELION Originated from Europe and Asia Description: Golden yellow flowers Round, fluffy seed head DANDELION Mode of Pollination: Wind Pollinated Feathery seeds produced to be dispersed by wind Small and light Capable of both self-pollination or cross-pollination Video: http://www.britannica.com/EBchecked/media/16679/D andelions-are-capable-of-both-self-pollination-and-crosspollination DANDELION Uses of dandelion: Dandelion leaves are used to add flavour to salads, sandwiches, and teas, to help the body get rid of excess fluid Roots are mainly used as an appetite stimulant, and for liver and gallbladder problems Flowers are used to make wines MIMOSA Scientific name: Mimosa pudica Mode of pollination: Insect (Bees), Wind MIMOSA Common Wind-Pollinated Flower Small, dull, may be even without petals Mimosa pudica P However it has pink flowers Nectar absent O For bees Usually unscented Large, feathery stigmas that protrude out of the flower Stamens are pendulous and protrude out of the flower Pollen produced in great abundance, small, lightweight with smooth surface Nectar guides absent P P P P P MIMOSA The Mimosa closes its leaves when touched or exposed to other stimuli like fire and wind. WHY? It is the result of the internal movement of water. A stimulus triggers certain areas of the stem to release chemicals, which cause water to move out of cell vacuoles and leads to cell collapse. This is an act of defense against herbivores. Mimosa is widely used in traditional medicine, because of its medicinal properties. It can even be used to combat glandular tumours and uterine cancer! However it is also a weed because it has prickles on its stem, and is easily found anywhere. MIMOSA Mimosa plant is easily found, and can cause weeding problems because of its prickles on its stem.
