segments, which are fleshy and covered with glandular hairs ; 

 the tube of the corolla is nearly cylindrical, 5 lines long, 

 yellow, and marked outside with 5 purplish lines, the border 

 is cleft into 5 rather equal roundish segments, each with a 

 purplish central line and a mucronulate apex, it is of a lilac 

 colour, and somewhat oblique, the upper lobe being more erect, 

 and the lower ones somewhat more reflected, the throat, of a 

 deep lilac hue, is compressed and hollowed inward on the front 

 side, in a somewhat personate form ; the stamens are unequal, 

 the 5 filaments arising from the contraction above the base 

 of the tube, are white and compressed, the short sterile 

 stamen is seen below the ringent compression of the tube, 

 between the. front and longer pair, while the upper pair is 

 somewhat shorter, the fertile anthers, which approach each 

 other by the inflection of the filaments, are 2-celled, ovate, 

 the 5th sterile one being smaller, erect and castrate. The 

 ovarium is oblong and smooth, 2-celled, laterally grooved on 

 each side, and seated on a somewhat 2-lobed, annular, fleshy 

 disc, the lobes corresponding with the grooves and the 

 edges of the dissepiment; the style is slender, greenish, 

 2-grooved and compressed at the summit, where it is de- 

 flected towards the upper pair of anthers in the mouth of the 

 tube, the stigma is somewhat clavate, or rather 2-labiate, 

 with a thin expanded margin, enclosing 2 large papillose 

 viscid glands. The capsule is small, obovate, smooth, en- 

 closed within the persistent calyx, 2-celled, 2-valved, with a 

 notch in the apex of each valve, where it splits half way 

 down by pressure. The seeds are attached by a point on 

 their ventral face to the thickened portion of the dissepim ent 

 that becomes free and is parallel with the valves : they are 

 numerous, light brown, and oval, the surface being divided 

 into rather large, deep areoles, separated by straight prominent 

 ridges. The embryo is cylindrical, slightly curved, the radicle 

 is somewhat thick in proportion to its length, the cotyledons, 

 scarcely broader than the radicle and half its length, are some- 

 what compressed and ovate.*
