A tree, in Florida sixty or seventy feet in height, with a massive straight trunk three or four feet 
in diameter, stout upright branches which form a dense irregular head, thick terete branchlets, and 
naked buds. The bark of the trunk varies from one third to one half of an inch in thickness and from 
a dark gray color to a light brown tinged with red, and is broken into thick plate-like scales which 
separate in thin plates. The branchlets, when they first appear, are orange-colored and slightly puberu- 
lous, later becoming light red to ashy gray and quite glabrous, and in the second year they are brown 
more or less tinged with red, marked with the conspicuous nearly orbicular leaf-scars, displaying 
three large fibro-vascular bundle-scars, and conspicuously roughened by the thickened persistent bases 
of the fruit-stalks. The leaves are oval, acute at the apex, or rounded and then occasionally slightly 
emarginate, and acute at the base, with thickened cartilaginous slightly undulate margins; when they 
unfold they are silky-canescent on the lower surface, and at maturity are thin and firm, glabrous, bright 
green and lustrous above, lustrous and yellow-green below, three to five inches long and an inch and a 
half to two inches broad, with broad pale conspicuous midribs deeply impressed on the upper side and 
inconspicuous primary veins arcuate near the margins and connected by prominent reticulate veinlets ; 
they are borne on slender pale petioles an inch to an inch and a half in length, and are mostly clustered 
near the ends of the branches, and, unfolding irregularly from early spring until autumn, fall at the 
close of the year. The flowers usually appear in Florida in the autumn, but also open in early spring and 
during the summer; they are five-parted, produced in many-flowered clusters from the axils of young 
leaves or on the branches of the previous year from leafless nodes, and are borne on stout orange-colored 
puberulous pedicels developed from the axils of minute acute scarious bracts which usually fall before 
the opening of the flower-buds. The calyx is yellow-green, puberulous on the outer surface and deeply 
divided into broadly ovate rounded lobes rather shorter than the light yellow corolla, the divisions of 
which are ovate-oblong and rounded. The staminodia are lanceolate, nearly entire, tipped with subulate 
points, and much shorter than the stamens, which have elongated filaments and lanceolate anthers. The 
ovary is oblong-ovate, glabrous, and gradually contracted into an elongated style, stigmatic at the apex. 
Usually only one flower in a fascicle produces a fruit; it develops in about six months, in Florida the 
principal crop ripening through April and May. The fruit, which is one-seeded, oblong, surrounded 
at the base by the persistent calyx, apiculate at the apex with the remnants of the style, and an inch
