| + | '''''Grindelia camporum''''' is a species of flowering plant in the [[Asteraceae|daisy family]] known by the common names '''Great Valley gumplant''' and '''Great Valley gumweed'''. It is native to [[California]] and [[Baja California]], where it can be found in a number of habitats. Its range may extend into [[Nevada]]. This hardy plant readily grows in disturbed and altered areas such as ditches and roadsides. It is a gangly weedlike perennial topping two meters in maximum height. Its erect, branching stems are lined with many stiff, wavy-edged, serrated leaves 2 to 3 centimeters long. Atop the stem branches are [[inflorescence]]s of a single large [[Head (botany)|flower head]] up to 3 centimeters wide. The head is a vaguely thistlelike cup of green clawlike [[bract|phyllaries]] that bend downward. The center of the head is filled with yellow disc florets and there are usually many yellow ray florets around the circumference. The flower head fills with a copious white exudate, especially during the early stages of blooming. This plant has a number of historical medicinal uses. |
