 the corolla is an erect 5-lobed corona, the truncate lobes 2 toothed, 

 projecting in a flap over the gynostegium. Stem and leaves canes- 

 cent, copiously milky. Leaves opposite, cordate or hastate, abruptly 

 curving into a long acute point, the largest 10 cm. in length. Fruit 

 an immense ovate follicle, sometimes 10 cm. long and 7 cm. broad 

 at the base. Seeds black, somewhat angled and tuberculate, linear, 

 6 mm. long, surmounted by a soft white silky coma 4-5 cm. long. 

 This plant is often cultivated in gardens at Asuncion, and the 

 abundant coma is used for making pillows, for which purpose it is 

 well fitted, as it is as soft as eider down.

Stem glabrous below, pubescent above and on the inflorescence.

 long, 3-5 cm. broad. Flowers in axillary clusters, 8-20 in the 

 cluster ; pedicels 1-1^ cm. long. Sepals erect, greenish in the 

 middle, white on the edges, obtuse, not half as long as the corolla. 

 Corolla lobes pointed, white without, dark purple or with purple 

 lines in the middle of the interior and yellowish on the margins, 6 

 or 7 mm. long. Corona of 5 scales, inflexed at the top in a spoon- 

 like projection. Stigma truncate. Fruit a smooth ovate pod 6-8 

 cm. long, 3-4 cm. broad at the base. This plant on the Pilcomayo 

 was growing in the water of the great laguna, twining about shrubs 

 that rose above the surface. At Asuncion it was in thickets. 

 Probably the laguna was an overflow of water, though we did not 

 remain there long enough to determine that.
