puberulons below, slender primary veins extending very obliquely to the end of the 

 leaf, with 1 or 2 pairs near the middle of the blade more prominent than those 

 below and above them, turning in the autumn yellow, orange, and brown; their peti- 

 oles slender, narrowly wing-margined above, glandular, at first hoary-tomentose, 

 becoming pubescent or pubendous, \'-^' long; on vigorous shoots broadly obovate, 

 short pointed at the apex, slightly undulate-lobed above the middle, conspicuously 

 reticulate-venulose, sonietimes 1^' long and broad. Flowers f'-f in diameter, on 

 slender elongated hoary-tomentose pedicels, in 3-5-flowered simple corymbs; calyx- 

 tube narrowly obconic, thickly covered with matted white hairs, the lobes gradually 

 narrowed from broad bases, acuminate, glandular, pilose on the outer, sparingly pilose 

 on the inner surface; stamens 20; anthers pale yellow; styles 3-5, surrounded at the 

 base by a thick ring of white hairs. Fruit ripening and falling in August, on slender 

 erect pubescent pedicels, globose, red, about ^' in diameter; calyx deciduous; flesh 

 thin, orange-yellow, and succulent; nutlets 3-5, narrowed and acute at the base, 

 rounded at the apex, flat and grooved on the back, with a narrow shallow groove, 

 about ^^' long. 



A tree, 12-15 high, with a trunk sometimes 8' in diameter, covered with thick 

 nearly black checkered bark, drooping branches forming a handsome symmetrical 

 head, and slender very zigzag branchlets clothed at first with hoary tomentum, 

 rather bright reddish brown and roughened by minute tubercles at the end of their 

 first season, becoming gray or grayish brown, and unarmed, or armed with occasional 

 short slender spines. 



Distribution. Sandy woods and abandoned fields; central Florida; common 

 near Eustis.

when the flowers open about the 20th of March and then almost glabrous above, 

 slightly hairy near the base below, and at maturity subcoriaceous, glabrous, about 1' 

 long and \'-^' wide, with slender yellow midribs and one pair of veins often more 

 prominent than the others and nearly parallel with the margins of the blade, turning 

 in the autumn yellow, orange, and brown; their petioles slender, conspicuously
