Hooveria parviflora

Hooveria parviflora is a species of perennial herb in the subfamily Agavoideae known by the common name smallflower soap plant. It is a monocot, native to coastal southern California and Baja California, where it is a member of the coastal sage scrub flora. It resembles a smaller version of Chlorogalum pomeridianum, with wavy leaves and white flowers that open during the day.

Description
Hooveria parviflora is a perennial wildflower, growing from a bulb 4 to 7 cm wide. The bulb is covered in a dark brown, membranous coat. The leaves emerge from the top of the bulb, and are long and narrow, with wavy margins, 3 to 9 mm wide.

The inflorescence is 30 to 90 cm tall, with ascending to erect branches. There are several flowers or buds per node. The pedicels, which suspend the flowers, are 2 to 8 mm long. On the flower, the perianth parts spread from above the base, and are colored a white to pink, with a darker midvein. The perianth is 7 to 8 mm in length, and the stamens are 3 to 4 mm long. Atop the stamens are yellow anthers. The style is 7 to 9 mm long. The fruits are 3 to 4 mm large, with 1 to 2 black, ovoid seeds per chamber.

The flower opens in the morning, and is closed by the evening, only being open for a single day.
