Osbeckia ulotricha

Why in News: Scientists from the Botanical Survey of India (BSI) have identified a new flowering plant in the Western Ghats, named Osbeckia ulotricha.

What to Know

• It is a newly identified flowering plant belonging to the Melastomataceae family.

• It was discovered in the shola grasslands of the Agasthyamala Biosphere Reserve in the Western Ghats.

Key Characteristics

• It is a woolly-haired species endemic to elevations of 1,200-1,500 metres.

• Its leaves are clustered at the apex.

• It has a sub-globose hypanthium, or an almost rounded flower base.

• The ovary is crowned with true bristles - fine, stiff hairs at the top.

• It also possesses an urn-shaped hypanthium with a neck.

• The plant flowers and fruits between February and May.

Habitat

• It mainly occurs along the damp margins of Tropical Montane Wet Temperate Forests (shola).

• It is also found along Montane Temperate Grassland ecosystems.

Agasthyamala Biosphere Reserve

• Location -> southern Western Ghats, covering parts of Kerala and Tamil Nadu.

• Established -> 2001.

• Included in UNESCO's World Network of Biosphere Reserves -> 2016.

• Vegetation includes tropical evergreen, semi-evergreen, moist deciduous, montane rainforest and shola-grassland ecosystems.

• Important rivers originating here include Thamirabarani, Neyyar and Karamana.

• Protected areas include Shendurney, Peppara and Neyyar Wildlife Sanctuaries, and Kalakkad-Mundanthurai Tiger Reserve.

Quick Recall

• Family -> Melastomataceae.

• Discovery site -> Agasthyamala Biosphere Reserve.

• Altitude -> 1,200-1,500 m.

• Flowers/fruits -> February to May.

• Agasthyamala -> Kerala + Tamil Nadu; UNESCO network since 2016.

Ophiorrhiza assamensis

Why in News: Botanists have discovered a new plant species, Ophiorrhiza assamensis, near Guwahati, Assam.

What to Know

• It is a new species of flowering plant found in a moist and shaded habitat near Guwahati.

• It is a perennial herb with large, ribbed leaves and clusters of small white flowers.

• It belongs to the Ophiorrhiza genus of the Rubiaceae family - the same family as coffee.

Why the Genus Matters

• The Ophiorrhiza genus is a natural source of camptothecin.

• Camptothecin is used in the development of medicines for cancers, including colon cancer.

Conservation Concern

• The species is currently known only from a highly localised population.

• This makes it vulnerable to deforestation and development-related habitat changes.

• Because its total population is unknown, researchers have classified it as Data Deficient under IUCN criteria.

Quick Recall

• Location -> near Guwahati, Assam.

• Family -> Rubiaceae.

• Genus -> Ophiorrhiza.

• Important compound -> camptothecin.

• Current IUCN assessment -> Data Deficient.

Northern Goshawk

Why in News: A rare Northern Goshawk, identified as Punjab's State Bird, has recently attracted attention.

What to Know

• It is a large and powerful bird of prey belonging to the Accipitridae family.

• It occurs across Europe, Asia and parts of North America.

• Its main habitat is dense forest, especially coniferous and mixed woodlands.

• IUCN Red List status -> Least Concern.

Key Features

• It has relatively short, broad wings and a long tail.

• Females are considerably larger than males.

• It is a partial migrant.

• Migration generally occurs during September-November and again during February-April.

• It is diurnal and is usually seen singly or in pairs.

• It is highly territorial and maintains its home range through display flights.

Hunting Style

• It is a powerful predator that mainly uses a perch-hunting strategy.

• This involves quick, low-level flights interrupted by brief periods of scanning from elevated perches.

• It is essentially a short-duration sit-and-wait predatory behaviour.

Quick Recall

• Family -> Accipitridae.

• Habitat -> dense coniferous and mixed forests.

• IUCN -> Least Concern.

• Behaviour -> diurnal, territorial, usually single or in pairs.

• Hunting -> perch-hunting.
