Grindelia fastigiata is sometimes considered one of the many varieties of grindelia hirsutula. The main characteristic is the lack of ray florets; flowerheads have only disc florets, yellow to orange in color, above a bell-shaped or hemispherical involucre lined by recurved, green, glandular phyllaries. Phyllaries remain quite thick right to the tip, and are shiny in texture.
Lower to mid stem leaves are oblanceolate, often lined with small, irregular teeth, while upper stem leaves are more linear, and dotted with small glands, giving them an irregular surface texture. Stems are light brown or greenish, usually erect.
This species is found in southeast Utah, northeast Arizona, northwest Colorado, southeast Colorado and northeast New Mexico.
