The small, green flowers of Pelitory, Parietaria hespera, are arranged close to the stem and below the leaves and thus are very obscure. This plant was growing near a waste bin enclosure in Phoenix, Maricopa Co., Arizona, USA on February 2010.

FRUIT: Small single seeded capsules enclosed in greenish sepals and bracts.

RANGE: This herb is native to North America and is generally distributed across the continent.

LEAVES: Elongate triangular leaves usually have a long tappered tip.

FLOWERS: Small, greenish and without showy petals.
