212 Plants Collected in Paraguay. 



flowers rose-tinged ; seeds flattish, almost oval, dark colored, not so 

 smooth or shining as in P. acuminatum. Many of the stem hairs 

 are glandular. 



Not only on the banks, but often growing in the water. It was 

 plentiful in the great laguna. 



MulilenlieclLia sagittaefolia, Meisn., D.C. Prod., xiv, 148. 



Pilcomayo River (1038). May. 



A twining plant with glabrous stems and numerous long, loose 

 spikes of small, greenish-white flowers, the spikes solitary, leafless, 

 6-15 cm. in length. Leaves with small capillary auricles or sub- 

 hastate at the base, the highest linear, lowest oblong or cordate- 

 ovate. Style short, trifid ; stigmas fimbriate. Fruit glabrous, 

 obtusely 3-angled. The sepals turn red in fruit. 



The plant from which my specimens were gathered was growing 

 on the top of an old palm stump which stood in the water of the 

 great laguna on the Pilcomayo River, and at its root was nesting a 

 colony of small red ants. How they got there through such an 

 expanse of water was a mystery. 



Coccolotoa Paraguayensis, Lindau in Eng. Bot. Jahr., xiii, 218. 



Asuncion (19Y a). November-April. = Balansa 2000. 



My specimens differ a little in some points from those of Balansa 

 as described by Lindau. A shrub 1-2 m. in height, canescent; the 

 branches glabrous, striate, rising at aii angle more or less acute. 

 Leaves of a tawny color, elliptical, coriaceous, entire, obtuse at the 

 apex, narrowed and subcordate at the base, 5-10 cm. long and 2-4 

 cm. wide, strongly reticulate-venose, the veins prominent beneath, 

 the lateral curving just before reaching the margin and running for 

 some distance along the edge. Petioles about 1 cm. long, glabrous, 

 canaliculate. Flowers white, alternate, in slender axillary racemes 

 5-10 cm. long, the rachis angular; pedicels. 1|- mm. long. Ochreae 

 caducous. Ochreolae scarcely 2 mm. long, lax, cup-shaped, bilobed. 

 Bracts 1 mm. long, acute, decurrent. Fruit obtusely 3-angled, 

 conical, truncate at base, 5 mm. long and 5 mm. broad, rather 

 loosely invested by the persistent sepals. Seeds fuscous, shining, 

 smooth.
