somewhat hyaline. Corolla 7 mm. long; posterior lobes united 

 nearly to apex; pubescent within tube, especially on anterior 

 side, pubescent in horizontal line over bases of posterior lobes; 

 within tube yellow, extending to base of anterior lobes, distally 

 and over lobes violet-blue, with longitudinal fine deep-violet 

 lines. Filaments glabrous, the postero-lateral pair slightly shorter, 

 its anthers equalling those of the antero lateral pair; posterior 

 filament represented by a tiny knob. Style glabrous, at apex bifid 

 and bearing two plate like stigmas. Capsule 2.5-3 mm. long, 

 globose -ovoid, glabrous, dehiscing septicidally, the lateral portions 

 of the septum adhering to the capsule wall. Placentae pro- 

 truding into the cells, not coalescent. Seeds .4 mm. long, cres- 

 centic-cylindric, truncate at the apex, brown, with evident longi- 

 tudinal lines and cross reticulations. 



Wet open soil, sandy or loam, at altitudes of 500 to 800 meters, 

 Tropical zone, llanos of upper Magdalena valley. Doubtless in the 

 Sabina of Bolivar and elsewhere in northern Colombia. Ranges 

 northward to Mexico.

Stems ascending, repent and matted below, becoming erect and 

 .3-.5 dm. tall, obscurely four-angled, finely pubescent with refiexed 

 appressed white hairs. Leaves .4-.6 cm. long, .07-. 1 cm. wide, 

 linear, obtuse, clasping (but not dilated) at base, nerveless beneath; 

 finely pubescent on the midrib beneath or glabrous throughout. 

 Pedicels solitary, 5-7 mm. long, finely pubescent with refiexed hairs. 

 Bractlets linear-subulate, less than .5 mm. long. Sepals: outermost 

 3.5 mm. long, linear-lanceolate obtuse; two median slightly shorter 

 but nearly similar, these three green, glabrous or nearly so, except 

 for a frequent terminal tuft of short hairs; the two innermost 3 

 mm. long, lanceolate-linear, acuminate, with broad scarious margins 

 and ciliate with minute white hairs. Corolla 5 mm. long; posterior 

 lobes united nearly to apex; externally minutely pubescent, within 

 slightly pubescent over bases of the posterior lobes, elsewhere 

 glabrous; within tube pale, yellowish on anterior side, lined with
