(Narrowleaf Gumweed - Spiny Tooth Gumweed)
Asteraceae (Composite Sunflower) Family
Plant is an upright or sprawling perennial with several branches bearing yellow daisy-like flower heads. Its preferred habitat is principally in cedar glades, rocky slopes and roadside embankments. Distribution is occasional in the Escambia region.
The leaves are lance-like or linear and more-or-less opposite on the stem. The color is dark green above and paler beneath; often downy along the leaf stalk and plant stem. The leaves may be crowded on the stem and appear to be whorled and folded. The tip is usually blunt and the base may be wedge-shaped with a short leaf stalk, or slightly eared.
The flowers are heads made up of 15 to 20 ray flowers. The disc flowers are bisexual in nature and symmetrical in form. Each flower is subtended by gummy overlapping bracts at the base. The flowers measure about 2 inches across. Both ray flowers and disc flowers are bright yellow. Flowers occur in late summer and early autumn.
Fruit is achene.
The gumweed, G. squarrosa, is a more widespread species of prairies and is occasionally seen in this area, but generally it is better adapted to higher elevations. Squarrosa has wider leaves and more rays per head.
