opake beneath, with subprominent midrib, and reddish fine pellucid nerves and reticu- 
lated veins, 1-24 in. long, 7-9 lines broad, on slender petioles 3-5 lines long; panicle 
terminal, laxly branched, as in 7. myrianthus, 3 in. long, 2 in. broad, bearing innumer- 
able very small flowers, on pedicels 1-13 line long; sepals membranaceous, 1 line long; 
corolla of a reddish hue, pruinose, membranaceous ; tube 1 line long; segments roundish,
