gined above, at first villose, becoming glabrous, ^'-f long. Flowers f in diameter, 

 on slender elongated hairy pedicels, in simple 1-o-flowered corymbs, with oblanceo- 

 late acuminate bright red caducous bracts and bractlets; calyx-tube broadly obconic, 



sparingly hairy, with long pale caducous hairs, the lobes gradually narrowed from 

 broad bases, acute, glandular, with minute bright red glands, glabrous; stamens 20; 

 anthers small, purple; styles 3-5, surrounded at the base by a narrow ring of short

 depressed-globose, bright red, marked by small dark dots, nearly ^' in diameter; calyx 

 prominent, with enlarged appressed lobes; flesh thin, yellow, dry and mealy; nut-

A tree, often 20 high, with a tall trunk 6'-8' in diameter, covered with nearly 

 black deeply furrowed bark brokens^into short thick closely appressed scales, wide- 

 spreading often pendulous branches forming a broad symmetrical handsome head, 

 and slender slightly zigzag branchlets covered when they first appear with pale 

 caducous hairs, soon becoming bright red-brown and lustrous, and dull reddish
