New Species of South American Plants 51 



peduncled, solitary or 2 or 3 together in the axils, the bracts 

 similar to the leaves, but spatulate and very unequal. Tube 

 of the involucre campanulate, 1.5 or 2 mm. long, the lobes 4, 

 reflexed, broadly ovate, short, the glands conspicuous, one or 

 more of them petaloid, the petaloid appendages unequal, un- 

 guiculate, the limb oblique, broader than long. Stamens ex- 

 serted, the anther-cells separated, globose. Pistil exserted, the 

 ovary 3-costate and 3-nerved, the 3 styles shorter than the 

 pilose ovary, distinct, 2-fid for about half of their length, erect 

 or slightly spreading. 



"Trailing to three feet and forming dense clumps. Sandy 

 seashore at Playa Brava, February 9." (Herbert H. Smith, 

 Colombia, No. 1919.) 

 Euphorbia (Anisophyllum) chiogenoides. 



Minutely puberulent, the leaves finely papillose on both 

 surfaces. Stems prostrate from a thick woody rhizome, the 

 base more or less woody, much branched, the branches very 

 slender, densely leafy, lightly angled. Stipules linear or nar- 

 rowly subulate, connected by an interpetiolar line that sometimes 

 bears one or more additional ligules. Petioles extremely short, 

 flat, as broad as long. Blades 4 to 9 mm. long and a half or two- 

 thirds as broad, oval, inequilateral with oblique subcordate 

 base and blunt summit, thick, pale-green, obscurely pellucid- 

 punctate, the reddish margin somewhat revolute, minutely 

 serrulate, 2 or more nerves erect from the base of the midrib and 

 one or more secondaries of similar character. Involucre sub- 

 sessile, one or two together in the axils, the tube campanulate, 

 1.5 to 2 mm. long, thick, the 4 lobes much shorter, triangular- 

 ovate, acute, more or less lacerate, recurved. Petaloid ap- 

 pendages reddish, very broad, very oblique, the summit emar- 

 ginate. Anthers minute, the thecae separated, globose. Styles 

 3, distinct, shortly bifid. 



"Prostrate, often 2 feet long. Common on open grassy 

 lands (pampas) below 1,500 feet. I have not seen No. 122 1 on 

 these lands, though it occurs in clearings near them. Collected 

 near Masinga, 250 feet, December 24, and August." (Herbert 

 H. Smith, Colombia, No. 77.) 



The same collected by Purdie. 

 Euphorbia (Dichilium) subtrifoliata. 



Glabrate or sparsely pilose, with spreading hairs. Branches 

 erect, elongated, very slender, sulcate, pale-green. Interpetiolar 

 stipules in^conspicuous. Petioles opposite or 3-verticillate, to 

 3 cm. or more long, filiform, divaricate. Blades 2.5 to 6 cm. 

 long, I to 2.5 cm. broad, ovate, with very shortly and broadly 

 cuneate base and obtuse but minutely apiculate summit, eatire ,
