About Mount Hamilton Lomatium (Lomatium observatorium) 0 Nurseries Carry This Plant Lomatium observatorium is a rare species of flowering plant in the carrot family known by the common names Mt. Hamilton desertparsley and Mount Hamilton lomatium. It is endemic to California, where it is known only from the mountains of Santa Clara County, including Mount Hamilton near the Lick Observatory. It may also occur in Stanislaus County. Its habitat includes mountain woodlands on volcanic and metamorphosed sedimentary rock substrates. The plant was described to science as a new species in 1996. This is a perennial herb growing low to the ground, the lightly hairy herbage growing from a long taproot. The leaf blades are up to 12 centimeters long and are intricately divided into many subdivided lobes, the smallest segments linear or lance-shaped and pointed. The blades are borne on petioles a few centimeters in length.
