Plants 1 or 1 1/2 inches high, annual. Leaves opposite, lanceolate, entire. Herbiage purple-brown, including the calyx. Flowers on short pedicels, solitary in the axils, spreading nearly but not quite horizontally, i.e. ascending a little. Calyx prismatic-angled, its teeth unequal, the upper the longer. Corolla-tube little exserted, its limb spreading at an abrupt angle after the manner of certain Nyctaginaceae. Limb flat, i.e. plane, 4 lines broad. Lobes 5, subequal. The limb is very obscurely bilabiate, that is, its bilabiate character can only be made

Stames 4, 2 long upper, 2 short lower, the anthers divergently 2-lobed and connivent in pairs. Stamens inserted on the summit of the proper tube which is very short, less than 1 line long; above the tube is the throat which is rather strongly distended or gibbous on lower side. Style
