Leaves persistent, oval, oblong or ovate, acuminate or rounded and apiculate at the apex, grad- 

 ually narrowed or broad at the rounded or subcordate base, entire, coriaceous, dark green, his- 

 pidulose-papillose and scabrate on the upper surface, pale and soft-pubescent on the lower surface, 

 from 5 to 13 centimetres long and from 3 to 8 centimetres wide, with thickened slightly revolute 

 margins, stout midribs, usually from eight to eleven pairs of prominent primary veins and conspic- 

 uous reticulate veinlets; petioles stout, rusty-pubescent, from lto2 centimetres in length ; stipules 

 concave at the base, gradually narrowed above into a long slender point, pubescent, from 1 to 2 

 centimetres in length. Flowers sessile or short-pedicellate in the axils of acute bracts, in axillary 

 pedunculate cymes on slender rusty-pubescent peduncles from 4 to 5 centimetres in length ; calyx 

 short-oblong, produced above the ovary into a four-lobed tube, densely pubescent on the outer sur- 

 face ; corolla often 2.5 centimetres in length, the slender tube retrorsely silky-villose on the outer 

 surface, the lobes five to seven, usually five, imbricated in the bud, oblong-obtuse ; stamens inserted 

 in the tube of the corolla, as many as and alternate with its lobes ; filaments free, short ; anthers 

 oblong-linear, included, two-celled, introrse, opening longitudinally ; ovary inferior, four-celled, 

 the cells tubular; style slender, shorter than the tube of the corolla; stigma capitate; ovule soli- 

 tary in each cell, suspended on the thickened funicle from the inner angle of the cell ; raphe 

 ventral ; micropyle superior. Fruit a fleshy one-stoned four- to nine-seeded subglobose pubescent 

 drupe from 6 to 7 millimetres in diameter and crowned by the persistent tube of the calyx ; flesh 

 thin and dry ; stone thick-walled, slightly angled ; seed compressed, suspended on the thick funicle 

 closing the orifice of the wall of the stone ; albumen thin and fleshy ; embryo elongated ; cotyle- 

 dons flat, minute, not longer than the elongated terete radicle turned toward the hilum. 



A tree, in Florida sometimes from 7 to 8 metres high, with a tall trunk from 5 to 6 centi- 

 metres in diameter, small ascending branches forming an open irregular head, and stout or slender 

 branchlets ascending at narrow angles, densely covered during their first season with rufous pubes- 

 cence, and light reddish brown, slightly pubescent and marked by the conspicuous leaf-scars in 

 their second year. Flowers produced irregularly during the winter and early spring. Fruit 

 ripens in the autumn. 1

1 The earliest figure of this tree appeared in Plunder's Nova Plantarum Americanarum Genera published in 1703, where it is
