Gumweed (Grindelia stricta var. platyphylla) is a native perennial herb that grows in Southern and Central California, primarily in the Central Coast region. It is a member of the Asteraceae and has typical sunflower floral structure with yellow disk flowers and ray flowers. It tends to grow in tidal flats, coastal strand, and coastal sage scrub typically very near the ocean, at elevations from 0-700 feet. There are three recognized varieties of Grindelia stricta; var. platyphylla is broadly distributed along the coast from Del Norte County to Los Angeles County and the northern Channel Islands. The flower bud is distinctive in having large amount of sticky white sap which native people use as an adhesive. The plant has a prostrate, sprawling habit and roots as it spreads.

Some botanists consider Grindelia paludosa a synonym for Grindelia hirsutula, a North American species of flowering plant in the daisy family known by the common names hairy gumplant and hairy gumweed. Grindelia hirsutula is native to North America, widespread across Canada and in California and Oregon. The species is highly variable, and many local populations have been named as varieties or as distinct species. All these taxa do, however, intergrade with one another. Grindelia hirsutula is an erect perennial herb or subshrub sometimes as much as 250 cm (100 inches or 8 1/3 feet) tall but usually much shorter. The plant is usually green but the stems are often red or purplish-brown and the leaves can be somewhat yellowish to reddish. The plant can produce numerous flower heads in branching arrays at the top of the plant. Each head is 2 or 3 centimeters (0. 8-1. 2 inches) wide with hemispheric cups of greenish phyllaries around the base, the bracts claw-like and bent away from the flowers. The center of the head is filled with many small yellow disc florets surround by numerous golden ray florets. The head produces a thick white exudate, especially in new flower heads.
Varieties: Grindelia hirsutula var. maritima - San Francisco Gum Plant, San Francisco gumplant, coastal gumweed; is endemic to the the San Francisco Bay Area in coastal northern California.

The tree is endemic to the Monterey Peninsula in coastal Monterey County, located on the Central Coast of California, in the Western United States. The tree is found in small, scattered populations, and not in large forests of its species. Hesperocyparis goveniana occurs with Hesperocyparis macrocarpa (Monterey cypress), in the two groves where the Monterey cypress is known to occur naturally, in Monterey County. It is on the IUCN Red List of endangered species. Hesperocyparis goveniana is an evergreen tree with a conic to ovoid-conic crown, very variable in size, with mature trees of under 1 m (3 ft 3 in) on some sites, to 50 m (160 ft) tall in ideal conditions. The foliage grows in dense sprays, dark green to somewhat yellow-green in color. The leaves are scale-like, 2-5 mm (0. 08-0. 20 in) long, and produced on rounded (not flattened) shoots. The seed cones are globose to oblong, 11-22 mm (0. 43-0. 87 in) long, with 6 to 10 scales, green at first, maturing brown or gray-brown about 20-24 months after pollination. The cones remain closed for many years, only opening after the parent tree is killed in a wildfire, thereby allowing the seeds to colonize the bare ground exposed by the fire. The male cones are 3-5 mm (0. 12-0. 20 in) long, and release pollen in February/March. Typically, cones of H. goveniana are smaller than those of H. macrocarpa. Taxonomy. The varieties or subspecies, formerly included under Cupressus goveniana by some botanists, include:Cupressus goveniana var. goveniana - reclassified as Hesperocyparis goveniana. Monterey County, strictly coastal, within 3 km (1. 9 mi) of the coast and below 200 m (660 ft) altitude. Foliage dark green, not rough, with leaf tips not spreading; cones globose. Cupressus goveniana var. pigmaea, reclassified as Hesperocyparis pygmaea - Mendocino cypress (vulnerable species). Mendocino and Sonoma counties, coastal, within 10 km (6. 2 mi) of the coast and below 500 m (1,600 ft) altitude. Cupressus goveniana var. abramsiana, reclassified as Hesperocyparis abramsiana - Santa Cruz cypress (endangered species). Santa Cruz and San Mateo counties, in the Santa Cruz Mountains 10-20 km (6. 2-12. 4 mi) inland and at 300-760 m (980-2,490 ft) altitude. With yellow-green foliage slightly rough-textured from the acute and slightly spreading leaf tips; cones often oval.

Cupressus macnabiana (McNab Cypress or Shasta Cypress) is a species of cypress endemic to northern California. It is one of the most widely distributed of all the native California cypresses, found growing in chaparral, oak woodlands and coniferous woodlands along the inner northern Coast Ranges and the foothills of the northern Sierra Nevada. It is an evergreen shrub or small tree, 3-12 meter (rarely to 17 meter) tall, with a spreading crown that is often broader than it is tall. The foliage is produced in dense, short flat sprays (unlike most other California cypresses, which do not have flattened sprays), bright waxy pale gray-green in color, with a strong spicy-resinous scent. The leaves are scale-like, 1-2 millimeter long with an acute tip, and a conspicuous white resin gland on the center of the leaf. Young seedlings produce needle-like leaves up to 10 millimeter long in their first year.

Cupressus nevadensis, now reclassified as 'Hesperocyparis nevadensis, with the common name Paiute cypress, is a species of cypress tree native to a small area in Sierra Nevada of California, in the western United States. The Paiute cypress grows in a small area of the Southern Sierra Nevada, within Kern County, California and Tulare County. It is found on soils of granitic origin at altitudes of 3,000-6,000 feet (910-1,830 m). It is found in pinyon/juniper and oak/pine woodlands, chaparral, and closed-cone-cypress forest habitats. The largest grove composed primarily of the species is located south of the town of Bodfish in the Lake Isabella region. There are eight or so other populations of much smaller, scattered stands in the Southern Sierras. Hesperocyparis nevadensis is a medium-sized evergreen tree with a conic crown, growing to heights of 10-25 m (exceptionally to 39 m), and a trunk diameter of up to 0. 5 m (exceptionally to 1 m). The foliage grows in sparse, very fragrant, sprays varying from dull gray-green to glaucous blue-green in color. The leaves are scale-like, highly glandular, resinous and aromatic, 2-5 mm long, and produced on rounded (not flattened) shoots. The seed cones are globose to oblong, 25-55 mm long, with 6 or 8 (rarely 4 or 10) scales, green to brown at first, maturing gray or gray-brown about 20-24 months after pollination. The male cones are 3-5 mm long, and release pollen in February-March. The cones often remain closed for several years, only opening after the parent tree is killed in a wildfire, thereby allowing the seeds to colonize the bare ground exposed by the natural fire. Like most California cypress, it is a pyrophyte, heavily reliant on wildfire for its regeneration. Fire suppression policies of the past decades have severely limited reproduction of this fire dependent species. It is on the IUCN Red List as a vulnerable species.
