“The gaudy leonine sunflower Hangs black and barren on its stalk, And down the windy garden walk The dead leaves scatter,- hour by hour”

Rare fossilised flower found, related to sunflowers. "A 45 million-year-old fossil flower found in northern Argentina has uncovered the evolutionary roots of Earth’s most populous plant family. Image can be viewed here. Called Asteraceae, the family includes dozens of domesticated species — from sunflowers, daisies and chrysanthemums to lettuce, artichoke and tarragon — and some 23,000 undomesticated plants. But despite its ubiquity, Asteraceae’s fossil legacy is sparse, containing little more than pollen grains. A few larger, detailed fossils exist, but they’re relatively young."
