Calycadenia mollis is an annual herb producing an erect, hairy stem up to 90 centimeters tall. The leaves are linear in shape and up to 8 centimeters long, the longest ones often toward the middle of the stem. The inflorescence bears several long clusters of small, very glandular flower heads, each of which has one or more white, yellow, or red triple-lobed ray florets around a center of disc florets. The fruit is an achene; those arising from the disc florets have a pappus of about eight scales.[4]
