Morphological description

Annual, rosettiform herb to 20 cm, glabrous at crown and in stem axils. Leaves basal, suberect-incurved, fusiform, 20-130 x 2-5 mm, mucronulate, succulent, green.

Diagnostic description

Distinguished from G. capillaris by the fusiform leaves and larger capitula, 4-10 mm diam., with 8 or 9 involucral bracts and ray florets and 30 disc florets. The perianth tube in the ray florets is longer than in G. capillaris, 1-1.5 mm long,with the style included and branching below the mouth of the tube. The ray ovaries and cypselas are glabrous.
