 pedicels 6-8 mm. long, the upper ones gradually shorter ; sepals spreading at right angles 

 to the corolla-tube, the larger ones 6 mm. long, the two smaller minute; corolla rose-col- 

 ored, 5-angled, 10 mm. long, its lobes pointed.

 sometimes rose-colored, bearing throughout its length scattered small ovate leaves free at 

 base and acute at each end ; inflorescence a simple secund raceme, at first strongly nod- 

 ding, about 15-flowered; buds arranged in two rows, obtusish ; lower pedicels elongated, 

 10 mm. long or less; sepals unequal, all much shorter than the corolla, ovate, acute; 

 corolla 1 cm. long, ptirplish with yellowish slightly spreading acute tips, the lobes united 

 for about one-fourth their length ; stamens 10, all inserted on the corolla-tube, the 5 oppo- 

 site the sepals inserted at the top of the tube, the other 5 inserted a little lower down on 

 the tube ; carpels erect, free to the base.
