Trees 12-25 m tall with a dense crown; branchlets opposite or irregularly arranged, stout, 3-6 mm diam.
Shrubs 2-4 m tall with branches in whorls; branchlets in 3's or subopposite or alternate, dark-brown to yellow-green; buds ovoid, 2 mm long, yellow-brown, the bud scales persistent, ovate to triangular-lanceolate, keeled, 1-1.
trees or shrubs 3-9 m, rarely to 25 m tall; bark scaly, red-brown, purple-brown or chestnut-brown; branches irregularly arranged, erect or spreading; branchlets slender, yellow-green or olive green to red-orange or orange-brown, the second-year shoots often remaining green, at least in part; winter buds ovoid, conical or ohovoid, 1.
Pollen strobili simple, solitary, subsessile, the peduncles to 1 mm long, axillary on first-year branchlets, globose before expansion then short oblong-cylindrical, 2.
Ovules solitary or occasionally paired in the axils of bracts on short branchlets or stalks which themselves are axillary on the first-, second- or occasionally third-year branchlet, sessile, subtending scales about 12-20, decussate, ovate to flabellate, concave, membranous, often rugose, nearly enclosed at maturity by the aril; arils open at the apex, 5-10 x 5-7 mm, green when young, sometimes remaining so, becoming orange or usually bright scarlet red at maturity; seeds hard, ovoid, 5-7 x 4-5 mm, becoming 2-4-angled at the apex, the hilum slightly depressed, ovate, triangular or square.
Plants endemic to small region in Florida, rare in cultivation; leaves often widely spaced on the branchlets T.
