Sweet basil or commonlycalled Niazbo in North India is botanically – Ocimum basilicum. It is commonly cultivated in gardens as a culinary herb and spreads as a weed. The purple coloured flowers are arranged in regular whorls and form a typical verticillaster inflorescence. It bears bi-labiate flowers, i.e. each flower has 5 sepals and 5 petals arranged in 2 lips – a larger and a smaller. Four stamens with half -fertile and half -sterile give it a typical didynamous condition.
The fertile stamens were gently pressed to release the pollen that were viewed under foldscope. Presence of staminal trichomes is yet another feature that was seen under foldscope.
