About Leptosiphon grandiflorus Benth.
Leptosiphon grandiflorus Benth. is an annual herb that grows a hairy stem with occasional leaves. Each leaf is divided into linear lobes that reach up to 3 centimeters (1.2 inches) long. At the tip of the stem, the inflorescence forms a loose cluster holding a few white or pinkish funnel-shaped flowers, whose lobes grow up to 1.5 centimeters (0.59 inches) long. This species blooms from April to July.
It is endemic to California, occurring only in the California Coast Ranges of the state's Central Coast and San Francisco Bay Area. It grows at elevations below 1,200 metres (3,900 ft), in habitats including chaparral, coastal prairie, coastal sage scrub, closed-cone pine forest, grassland, and oak woodland. Leptosiphon grandiflorus is listed as a Vulnerable species by both the California Department of Fish and Wildlife and the IUCN, and it is included in the California Native Plant Society Inventory of Rare and Endangered Plants. Many previously documented occurrences of this plant have been extirpated, so its current total range is uncertain.
