Annual Sunflower

One of the world's most cultivated flowering plants and an economically critical oilseed crop, sunflowers are native to North America and can reach 3 meters in height with flower heads up to 30 cm across. Their distinctive behavior of tracking the sun — solar heliotropism in young plants — gave them their name. A single sunflower head consists of up to 2,000 tiny individual florets. Global production exceeds 50 million tonnes annually, valued for oil, seeds, and birdfeed.

common greasewort

<em>Aneura pinguis</em>, commonly known as common greasewort, is a liverwort belonging to the genus Aneura within the family Aneuraceae. This cryptogamic plant inhabits ecosystems across Asia, Europe, and North America, thriving in moist or waterlogged environments. Its range encompasses Taiwan in Asia, six European countries, the United States in North America, and Brazil and Colombia in South America, indicating a broad geographic distribution across multiple continents. Common greasewort is assessed as Least Concern on the IUCN Red List. The species typically forms flat, ribbon-like thalli in damp habitats such as stream banks, wet rocks, and boggy ground. Biological traits of this species remain poorly documented in the scientific literature.
