pedicels, in villose few-flowered narrow corymbs; calyx-tube narrowly obconic, glabrous 

 or slightly hairy toward the base, the lobes linear-lanceolate, usually entire or obscurely 

 glandular-serrate, glabrous on the outer surface and puberulous on the inner surface; 

 stamens 20; anthers small, rose color; styles 2 cr 3. Fruit ripening early in October or in 

 November, on stout glabrous or slightly villose pedicels usually about ' long, in drooping 

 few-fruited clusters, short-oblong, rounded at the ends, slightly pruinose, dull green tinged

with red, \'-\' long, with a prominent calyx-tube and elongated spreading lobes puberulous 

 on the inner surface and often deciduous before the ripening of the fruit; flesh very thin, 

 green, dry and hard; nutlets 2 or 3, with a broad low rounded ridge, \' long. 



A tree, in low moist ground sometimes 40 high, with a trunk 1 in diameter, free of 

 branches for 18-20, stout horizontal branches forming a broad round symmetrical 

 head, and nearly straight branchlets villose when they first appear, soon glabrous, light 

 chestnut-brown becoming dark gray-brown in their second or third year, and armed with 

 stout or slender straight chestnut-brown spines l'-2' long; or on the dry soil of low hills 

 much smaller and generally 20-25 high. 



Distribution. Low wet woods on the borders of streams, and on dry hills in forests of 

 Oak and Pine; near Marshall, Harris County, Texas; Natchitoches, Natchitoches Parish, 

 Louisiana.

Leaves oblong to obovate, rounded and obtuse at apex, gradually narrowed to the con- 

 cave-cuneate entire base, and coarsely serrate above with acute or rounded teeth, when 

 they unfold tinged with red, sparingly villose above and tomentulose below, nearly fully 

 grown w r hen the flowers open the middle of April, and at maturity coriaceous, dark 

 green, lustrous, and glabrous or scabrate above, pale and pubescent below, l'-2' long, 

 and l'-lj' wide, with a slender midrib and thin primary veins; turning in the autumn 

 yellow, orange, and brown; petioles stout, at first hoary-tomentose, glabrous at matur- 

 ity, about \' in length; leaves on the end of vigorous shoots, broad-obovate, short-pointed 

 at the rounded apex, often 2' long and \\' wide, with a prominent midrib and primary 

 veins. Flowers f '- f' m diameter, on short stout hairy pedicels, in usually 8-10-flowered 

 very compact corymbs densely clothed with long matted pale hairs; calyx-tube nar- 

 rowly obconic, villose, the lobes acuminate, glandular-serrate, villose on the outer and 

 slightly pilose on the inner surface; stamens 18-20; anthers pale rose color, styles usually 

 2 or 3. Fruit ripening in October, on stout glabrous stems, in compact drooping few- 

 fruited clusters, globose to subglobose or short-oblong, about f ' long, dark red; calyx prom-
