[99.] White cupfruit

Also called “tackstem” because of the numerous dark-colored, tack-shaped glands protruding from the stem, this white-flowered, branching annual blossoms from March to May at elevations of 500 to 4,000 feet. It is a conspicuous item of the spring flower display from west Texas to southern California and northern Mexico. A similar species with yellow flowers, Calycoseris parryi, common at elevations around 3,000 feet, blooms in March and April. It is found in southwestern Utah, Arizona, and southern California.

[100.] Prickly sowthistle

Naturalized from Europe and generally considered a weed, sowthistle is found in waste grounds and along roadsides from near sea level to 8,000 feet. It blossoms from February to August, the flowers becoming cottony seed heads as conspicuous as the blooms. A close relative, Sonchus oleraceus, which blossoms from March to September, produces a gum from the drying of the sap, reportedly a powerful cathartic. It has also been used as a treatment for persons suffering from the habitual use of opium derivatives.
