5a. ssp. floridanum (Chapm.) Desmarais (southern sugar maple; Florida maple)

A. saccharum var. floridanum (Chapm.) Small & A. Heller

A. nigrum F. Michx. var. floridanum (Chapm.) Fosberg

A. floridanum (Chapm.) Pax

A. barbatum Michx.

Bark light gray, smooth, becoming shallowly furrowed and sometimes with scaly ridges on older trees. Leaf blades 3–10 cm long, the undersurface pale green to whitish-glaucous and usually also hairy, the lobes blunt to rounded at the tips, usually with few secondary lobes or teeth, the sinuses between the main leaf lobes forming angles of less than 90°, the margins often slightly curled under. Calyx with dense white hairs on the inner surface that often extend past the lobes. Flower stalks elongating to 3–6 cm, usually hairy. Ovary and young fruit hairy (becoming nearly glabrous at maturity). April–May.

Uncommon in southern and central Missouri (southeastern U.S. west to Oklahoma and Texas). Mesic upland forests, ledges and bases of bluffs, and banks of streams, rarely bottomland forests.

This uncommon taxon is perhaps the most distinctive element within the sugar maple complex in Missouri, by virtue of its beechlike bark and relatively small leaves. It is most common along the Atlantic and Gulf Coastal Plains and is at the edge of its range in Missouri. See the treatment of ssp. schneckii for discussion of specimens that have intermediate leaf characters between ssp. floridanum and ssp. saccharum.
