Calycadenia multiglandulosa
About Sticky Calycadenia (Calycadenia multiglandulosa) 0 Nurseries Carry This Plant Calycadenia multiglandulosa is a species of flowering plant in the daisy family known by the common name sticky western rosinweed. It is native to central California, where it is a common member of the flora in a number of habitat types. Its range extends into western Nevada. This is an annual herb producing an erect, hairy, hairy stem up to 70 centimeters tall. The leaves are linear in shape and up to 8 centimeters long. The flower cluster is a series of dense clusters of flower heads surrounded by long, narrow leafs covered in obvious bulbous glands. The sticky, hairy 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.
