description
Vegetative characteristics
Lomatium caruifolium is a perennial herbaceous plant that reaches heights of 15 to 45 centimeters. A slender taproot is formed. One stalk is practically missing.
The leaves are divided into a petiole and a leaf blade. The petiole is 4 to 7 inches long. The bald to slightly rough or hairy leaf blade is 5 to 30 centimeters wide, triangular-ovoid to obovate and several times tripartite or pinnate. The segments are 2 to 60 millimeters long.
Generative characteristics
On a 10 to 40 centimeter long inflorescence stem stands the upright or to the side spread, double-ended inflorescence . The bracts are sessile or not. The 6 to 16 single umbels measure 1 to 12 centimeters in length and are spread out in an ascending manner.
The yellow or seldom purple petals are lanceolate to ovate, with a length of 2 to 8 millimeters, with entire margins or serrated, thin and veined.
The smooth double axis is ovoid to obovate with a length of 6 to 13 millimeters. The "wings" are thickened and less than half as wide as the actual fruiting body.
Occurrence
The two varieties of Lomatium caruifolium are unique to California. It occurs in the California Long Valley and in the foothills of the Inner California Coast Mountains and the Sierra Nevada . It was also found at altitudes of 60 to 600 meters in the north and south of the California Coast Mountains, in the foothills of the Cascade Range , in the Sacramento Valley , in the San Francisco Bay area and on the California Channel Islands .
Lomatium caruifolium grows in clayey areas of damp depressions, on temporary bodies of water and in open grasslands.
Systematics and distribution
The first description was in 1841 under the name ( Basionym ) Ferula caruifolia by William Jackson Hooker and George Arnott Walker Arnott in The Botany of Captain Beechey's Voyage , page 348. The new combination to Lomatium caruifolium (Hook. & Arn.) Coult. & Rose was published in Contributions from the United States National Herbarium , Volume 7, Issue 1, page 216 by John Merle Coulter and Joseph Nelson Rose in 1900 . Other synonyms for Lomatium caruifolium (Hook. & Arn.) Coult. & Rose are: Cogswellia caruifolia (Hook. & Arn.) MEJones , Peucedanum caruifolium (Hook. & Arn.) Torr. & A.Gray .
From Lomatium caruifolium there are two varieties:
