  • New species: Abelmoschus Odishae

    odisha

    Central Idea

    • A scientist from the Indian Council of Agricultural Research (ICAR) recently discovered a new plant species of ‘wild okra’ named ‘Abelmoschus Odishae’.

    Wild Okra (Abelmoschus Odishae)

    • Its discovery occurred in a humid deciduous forest within the Banspal block of Keonjhar district, in Odisha.
    • This plant holds potential for use in hybridization to develop improved varieties with enhanced disease resistance.
    • It could significantly contribute to broadening the genetic diversity of okra.
    • Characteristics:
      1. This perennial shrub reaches up to 5 meters in height and features a densely hispid, spiny stem with backward-facing hairs.
      2. The plant is adorned with large, vibrant yellow flowers.
      3. Its seeds are nearly kidney-shaped, with short, robust, non-spiral trichomes.
      4. The seeds exhibit a high viability rate of 95 percent.

    About Okra

    • Commonly referred to as gumbo or ladies’ fingers, okra is a vegetable favored in warm climates.
    • Originating from the Eastern Hemisphere’s tropics, it is now extensively grown or found naturally in the tropical and subtropical regions of the Western Hemisphere.

  • Specie in news: Lantana Camara

    Lantana Camara

    Central Idea

    • In an exhibition in Bengaluru, sculptures of elephants made from Lantana camara gained popular attraction.

    About Lantana Camara

    • Lantana camara, commonly known as lantana, belongs to the verbena family (Verbenaceae) and originates from the American tropics.
    • Lantana was introduced to India in the early 19th century as an ornamental plant during the British colonial period. Its colorful flowers made it popular in gardens.
    • This shrub has the ability to spread across forest floors, climb like a creeper over trees, and easily intertwine with native vegetation.
    • Lantana is highly adaptable, thriving in diverse ecosystems.

    Impacts on Local ecosystem

    • Lantana’s invasive nature poses a serious threat to native flora and fauna. It competes with native plants for resources, often leading to a reduction in native biodiversity.
    • It forms dense thickets that alter the structure of habitats that impede the movement of animals and change the microhabitat conditions, such as light availability and soil composition.
    • It can invade agricultural land, reducing crop yields, and can also infest pastures, impacting grazing for livestock.
    • It is toxic to livestock and can cause health issues if ingested. This adds to the economic burden for farmers who need to ensure their animals do not graze on lantana-infested land.
    • The plant increases the risk of fire in the ecosystems it invades because it forms dense thickets that can easily catch and spread fire.
