Calycadenia multiglandulosa is a species of flowering plant in the sunflower family, known by the common names sticky calycadenia and sticky western rosinweed. It is endemic to California, where it is a common in the Coast Ranges and in the Sierra Nevada Foothills from Shasta County to Kern County.


This is an annual herb producing an erect, hairy, glandular stem up to 70 centimeters (28 inches) tall. The leaves are linear in shape and up to 8 centimeters long. The inflorescence is a series of dense clusters of flower heads surrounded by long, narrow bracts covered in obvious bulbous glands. The sticky, glandular flower head has a center of several disc florets surrounded by a few white, yellow, or red ray florets. Each ray floret has three lobes at the tip, the middle lobe being shortest. The fruit is an achene; those developing from the disc florets have a pappus of scales.
