Flowers 12–15 mm diam.; sepals deciduous, not enclosing capsule, 5, linear-subulate, unequal, 5–7 × 0.5 mm, not glaucous; petals 5, bright yellow, oblong-spatulate, 7–9 mm; stamens deciduous, 75; ovary 3-merous; styles 2.5–4 mm. Capsules narrowly pyramidal-ovoid, 6 × 2.4 mm. Seeds not carinate, 0.6–0.8 mm; testa finely foveolate-reticulate.

Discussion
Hypericum chapmanii differs from H. fasciculatum in its taller, single-stemmed habit, thicker stems (to 10–15 cm diameter) with fluted, spongy bark containing large laticifers, and fewer-flowered inflorescences.
Hypericum chapmanii is known from the panhandle of northwestern Florida.
