 A very large evergreen tree ; stems reaching 80 to 100 feet (Curtis), 

 100 to 120 feet (Kunstler) in height, with a girth of 10 to 12 feet ; 

 branchlets rough, prominently marked with the scars of fallen leaves, 

 upper branchlets and innovations slightly but minutely rusty-pubescent. 

 Leaves coriaceous ; clustered at the ends of the branchlets, obovate 

 or obovate-oblong, abruptly and very shortly acute at the otherwise 

 rounded apex, cuneate at base ; margins slightly recurved ; glabrous 

 on both surfaces, the lower with very minute glandular scales ; 3 to 4 

 in. long, 1-5 to 2-5 in. broad; midrib prominent, impressed above; 

 main-nerves very obscure, about 14 to 16 pairs, inclined at nearly 

 70° to midrib and at first parallel, afterwards arching, reticulations 

 very faint ; petiole '1 to 1 in. long, edged above with the decurrent- 

 margins of the blade, glabrous. Flowers fasciculate, clustered about 

 2 to 4 together in the axils of the leaves or of the scars of fallen 

 leaves, often on a length of as much as 4 to 5 in. of the branchlet ; 

 pedicels and calyx minutely ferruginous-pubescent ; pedicels "1 to '15 in. 

 long, thick. Calyx-lobes 6, the 3 outer valvate rounded, the 3 inner 

 imbricate acute, -15 to -2 in. long. Corolla campanulate, tube as long 

 as calyx ; lobes 6, ovate, spreading, as long as tube, glabrous except a 

 slight rusty pubescence within. Stamens 12, the 6 longer opposite to, the 

 6 shorter alternate with, the corolla-lobes ; filaments inserted on the top 

 of the tube, slender ; anthers ovate, apiculate, extrorse. Ovary Qattened-
