papaveraceae

Papaveraceae, commonly known as the poppy family, is a group of flowering plants in the order Ranunculales. The family comprises about 40 genera and 700–800 species, distributed across temperate and subtropical regions worldwide, with notable diversity in Eurasia and the Americas. Most members are herbaceous annuals or perennials that exude a milky latex when damaged.

Morphology and characteristics include typically alternate, often deeply lobed or dissected leaves; erect stems that may be branched; and large, showy flowers. Flowers are usually solitary, actinomorphic, and commonly have four petals arranged around a central column of numerous stamens. The ovary is typically superior, developing into a capsule that dehisces at the top to release seeds. Petals are frequently vivid in red, yellow, or white, and the flowers often close at night or in dull weather. The family includes both annual and perennial species, many adapted to open, sunny habitats.

Taxonomy and diversity: Papaveraceae sensu lato includes several well-known genera such as Papaver (true poppies), Eschscholzia (California poppies), Glaucium (horned poppies), Meconopsis (blue poppies), and Argemone. The group known as Fumarioideae in some classifications, which includes Corydalis and Dicentra, is now treated as a subfamily within Papaveraceae. The family shows considerable variation in floral form, with Papaveraceae members typically possessing regular flowers, while some subgroups display more specialized, irregular morphologies.

Ecology and uses: Several species produce latex rich in alkaloids, most famously Papaver somniferum, the source of opium, morphine, and codeine. Seeds of cultivated poppies are edible and widely used in baking. Ornamental poppies, including Papaver orientale and Eschscholzia californica, are popular in gardens for their colorful blooms.
