Wineflower

Boerhavia diffusa is widely dispersed, occurring throughout India (where it is known as punarnava and used in Ayurveda,), the Pacific, and southern United States. Flowers are small, around 5 mm in diameter. Pollens are round, roughly 65 microns in diameter. This wide range is explained by its small fruit, which are very sticky and grow a few inches off the ground, ideally placed to latch on to small migratory birds as they walk by.

Inflorescence Small umbels forming Corymbose, axillary and terminal panicle. Flowers

Bracteoles, acute. Perianth -tube constricted above the ovary, limb funnel-shaped, dark-pink, with 5 vertical bands outside. Stamens 2 or 3, slightly exserted, unequal. Ovary superior, oblique, ovule 1, erect, stigma. Fruit Achene rounded, 6-ribbed. Seed Minute, albuminous with endosperm. Embryo curved.
