Nature's ingenious pollination trick! Ceropegia spiralis (Spiral Ceropegia) is now in bloom at BSI, Hyderabad. Its flowers act as temporary natural traps, attracting tiny flies with their scent, guiding them to transfer pollen and then safely releasing them after pollination🌸🪰

On the occasion of the 137th Foundation Day of the Botanical Survey of India, I extend my warm greetings and best wishes to all scientists, officers, staff, research scholars, post-doctorate fellows, outsourced employees and well-wishers of the organization. For more than a century, the BSI has remained at the forefront of exploring, documenting, and conserving the rich plant diversity of our nation. Our scientists, botanists, and field staff have tirelessly worked in some of the most challenging terrains—from the mighty Himalayas to the depths of dense forests where sunlight scarcely reaches, and across the slippery slopes of the Western Ghats where new species continue to bloom. Their dedication and perseverance have helped unveil many of nature’s hidden treasures. Our journey to discover and document India’s unique plant diversity will never cease, for biodiversity continues to surprise us with new forms of life. The work of the Botanical Survey of India is vital in deepening our understanding of the country’s natural heritage and strengthening conservation efforts for a sustainable future. Together, let us continue to make the Botanical Survey of India a global leader in plant science and biodiversity research and a proud institution of Atamnirbhar Bharat. - 𝑫𝒓 𝑲𝒂𝒏𝒂𝒅 𝑫𝒂𝒔, 𝑫𝒊𝒓𝒆𝒄𝒕𝒐𝒓, 𝑩𝑺𝑰

The sedge family (Cyperaceae) ranks among the ten largest families of flowering plants and is the third largest among monocotyledons. The tribe Fimbristylideae includes the genera Eleocharis (302 spp.), Fimbristylis (320 spp.) and Bulbostylis (227 spp.), together comprising about 849 species worldwide, of which 166 taxa are reported from India. During the present study, 86 taxa were documented from Tamil Nadu. The tribe is morphologically complex and widely distributed across plains, coastal areas, wetlands, and high-altitude regions. No detailed study has previously been conducted on nutlet morphology and micromorphology in this group. The present work provides a comprehensive account of the tribe with updated information, detailed descriptions, lucid identification keys, and highlights unique nutlet features, surface texture, shape, size, and colour, that are critical for delimiting taxa. Scanning Electron Microscopy (SEM) and Nikon SMZ1500 stereomicroscopy were employed to generate high-resolution images of nutlets, spikelets, glumes, styles, and stigmas, facilitating accurate differentiation and identification. The study also assesses around 21 endemic species from Tamil Nadu. Taxonomic confusion and misidentification of closely allied species in herbaria have been resolved through clear systematic evidence. Overall, this book serves as an illustrative guide to sedges, providing quick identification tools and encouraging further research in Cyperaceae by scientists, researchers, and students. researchgate.net/publication… @saveindiantrees @rksbsiadsingh @SDG15LifeOnLand @SDG2030 @SDGaction @SDGoals @bsi_moefcc @NationalBiodiv @NYBG @queensbotanicl @RBGCanada @myriadgardens @moefcc @PMOIndia @narendramodi @IUCN @IUCN_forests @IUCNAsia @IUCN_forests

🕊️ Nature’s Symphony at Keoladeo! 🌿 Perched gracefully on the branches of Vachellia nilotica trees, Painted Storks and Oriental Darters turn Keoladeo National Park into a living canvas each winter. 🪶✨ As the chill sets in, this UNESCO-listed Ramsar site in Rajasthan comes alive with a burst of color and song — migratory birds arriving from afar, mingling with the park’s proud residents. From the elegant Asian Woolly-necked Stork to the vibrant Alexandrine Parakeet, every corner here celebrates life, flight, and freedom. 💚 🌏 India’s National Bird Day — celebrated on the birth anniversary of Dr. Salim Ali, the legendary “Birdman of India” — honors his remarkable contributions to ornithology and the conservation of our avian heritage. 🐦🇮🇳 📍 Keoladeo National Park, Bharatpur — where every season tells a new story of wings and wonder. #NationalBirdDay #SalimAli #BirdmanOfIndia #KeoladeoNationalPark #Rajasthan #BirdPhotography #WildlifeIndia #NatureLovers #Birdwatching #Conservation #MigratoryBirds 📸Dr Ravi Kiran Arigela, Scientist C, @Bsi_azrc_JU
