Mother Nature Aug /Sep 2017 19 The corpse flower is what is called an inflorescence — a stalk with many flowers The corpse flower is what is called an inflorescence — a stalk with many flowers, according to the University of California Botanical Garden. A mixture of tiny male and female flowers grow at the base of the spadix, the central phallus-like structure, which is surrounded by the spathe, a pleated skirt-like covering that is bright green on the out- side and deep maroon inside when opened. If pollinated, the spadix grows into a large club-like head of orange-red seeds. Corpse flowers can take up to seven years to bloom; some corpse flowers only bloom once every few decades. The plant's energy is stored in the corm – a swollen stem base typically weighing around 100 lbs. (45 kilograms). The corpse plant has the world's largest known corm, sometimes weighing up to 220 lbs. (100kg). During the non-flowering years, a single leaf, the size of a small tree, shoots up from the corm. This leaf branches out into three sections with each of these sprouting more leaflets. Each year, this shooting leaf dies and a new one grows in its place. After many years, the plant finally gath- ers enough energy to bloom, and once it does, it can only hold the bloom for 24 to 36 hours before it collapses. Once the blooming begins, it occurs in two stages on con- secutive nights: essentially a "female" stage and a "male" stage. The female flowers form a ring at the bottom of the spadix (inner tube structure), and the male flowers form a ring around the spadix just above the female flowers. During the first stage, carrion beetles drawn by the stench of death and human-like body temperatures, creep inside the vase-like structure and unknowingly deposit pollen on the receptive female flowers. During the second stage, the structure begins to collapse, the "fragrance" fades and the insects begin to head out. As they leave, the beetles rub up against the pollen in the male flowers and are now ready to carry the pollen to a nearby female flower. Basketbal/Baseball plant It is generally known as euphorbia obesa native to South Africa. The plant has exactly the same shape of a baseball. It is an unbranched plant with an average height of 20 cm. The special species of base- ball plant is protected by national nature conservation as it is very rare in the world. Male and female flowers of euphorbia obesa grow on different plants.The female has three protruding stigma on which the pollen grains stick, whereas the male has a hairy like center covered with yellow pollen. Once pollinated the female plant produces fruitcontaining 3 seeds each. Baseball plants are quite toxic, makes severe skin problems.
