Presidio Clarkia (Clarkia franciscana)
Description
The Presidio clarkia, Clarkia franciscana, is an erect annual herb growing up to about 40 centimeters in maximum height. The leaves are narrowly lance-shaped and up to about 3.5 centimeters long. The top of the stem is occupied by the inflorescence, which bears opening flowers and closed, erect flower buds. The sepals stay fused together as the petals bloom from one side. The small corolla is bowl-shaped, with petals up to 1.3 centimeters long and wedge-shaped with mostly flat tips. The petals are lavender-pink in color, darkest at the tips and lightening to nearly white at the base, where there is a deep red spot. The plant is self-pollinating. The population sizes are variable from year to year; sometimes there are no plants seen at all, the seed banks remaining dormant until conditions improve.
