compressed near the tips, terete below. Leaves obovate, suddenly con- 

 tracted into a linear or sublinear narrow acumen, (about J in. long), 

 more or less cuneate towards the base, 5-7 in. long, 2-3 in, broad, sub- 

 coriaceous, quite glabrous ; secondary nerves 11-12 on each side, very 

 oblique, straight, like the midrib much raised below, less so (but distinctly) 

 above ; transverse veins numerous, parallel, raised on both sides, subhori- 

 Kontal ; petiole rather stout, 3-4 lin. long. Panicles over h ft. long, very 

 lax, pubescent below, glabrous above ; peduncle 2 J in. long ; lower bracts 

 at the base of the primary branches sometimes foliaceous, white, upper 

 very small, lanceolate to subulate, all pubescent; lowest branches up to 3 in. 

 long, undivided for f of their length; pedicels slender, up to 4 lin. 

 long. Calyx oblong-ovoid, 2 lin. long, glabrous; segments ovate- 

 lanceolate or oblong, subobtuse, ciliolate, thin ; intra-calycular glands 5. 

 Corolla white with red streaks in the throat ; tube wide-funnel-shaped, 

 3 lin. long, glabrous without and above the minute calli within ; lobes 

 linear, obtuse, 7 lin. long, over 1 lin. broad. Anthers scarcely 2 lin. 

 long ; connective scantily pubescent on the back. Disc distinct. Carpels 

 hairy at the top. Style obconical, glabrous, much shorter than the 

 conical shortly apiculate stigma, the lower edge of which projects into 

 a deflexed rim. — Codonura calophylla, K. Schum. in Engl. & Prantl,
