Species: Madia minima
Encyclopedia of Puget Sound
Small-headed tarweed is an annual with stems up to 10 cm (4 in) high, and long, slender branches from near the base. The (usually) opposite leaves, 1-2 cm long, are linear and long-pointed. Foliage is sparsely hairy below and glandular above. Small clusters of flower heads occur on the ends of the short terminal branches. Each head has 3-5 glandular, involucral bracts, 2-4 mm high, enclosing a ray flower. The yellow rays are minute, and there is a solitary, yellow disk flower surrounded by small bracts. The curved seeds (achenes), enclosed in the glandular bracts, resemble a section of orange.
