Near Chamaesyce portoricensis (Urban) comb. nov. (Euphorbia por- 

 toricensis Urban Symb. Antill. 1:338. 1899). Our species differs 

 strongly in its oblong, mostly crenate-dentate leaves, inyolucral teeth 

 and appendages, and larger, smooth, triangular seeds. 



Chamaesyce anegadensis sp. nov. 



Annual from a wiry root; plants short-stemmed, prostrate, rosulate- 

 spreading, densely white- villous; branches tenuous, short, 2-5 cm. 

 Inf orescence solitary, terminal in the bifurcations and axils. Leaves 

 opposite, thick, suborbicular, 3-6 mm. long, pilose on both surfaces, base 

 strongly oblique-cordate, apex obtuse, margin entire, revolute; petioles 

 short, about i mm.; stipules deltoid, densely ciliate-margined. Invo- 

 lucres turtinate, pilose without and within, pedicel about the length of 

 the tube, lobes broadly deltoid, tufted-ciliate, sulcus V-shaped, ciliate; 

 glands transverse, oval, green; appendages sarcous, white or pinkish, 

 about the width of the glands, margin entire, ciliate; bracteoles tomen- 

 tose; pedicels of the male flowers ciliate, of the female glabrous below and 

 woolly above; ovary densely woolly; styles distinct, short, bifid to the 

 base or nearly so. Capsule ovoid, long white-pilose even in age; seed 

 ovoid-triangular, acute, .9 x .6 mm., pinkish, the coat cellulo-farinose; 

 angles strong and sharply defined; facets smooth, convex.

Near Ch. portoricensis (above) from which it differs specifically in 

 its long-hairiness; thicker, larger, suborbicular leaves, short petioles, 

 entire stipules and its triangular smooth seeds. 



Chamaesyce nirurioides sp. nov. 



Annual; plants low, glabrous, erect or ascending; stem red, ligneous, 

 terete; branches alternate, 5-10 cm. Inflorescence solitary in the 

 terminal bifurcation and the axils of the upper leaves. Leaves opposite, 

 appressed, obovate, 3-nerved, oblique at the base, obtuse, margin 

 serrate-dentate especially at the upper third; petioles i mm. Stipules 

 interpetiolar, deltoid, thick, the margins glandular punctate. Involucres 

 long-pedicellate, campanulate, glabrous without and within; lobes 

 elongated triangular, few ciliate at the apex; glands waxen, orbicular, 

 cupped; appendages white or pink, orbicular, thrice the diameter o.f the 

 glands, entire or mostly so; male flowers glabrous; female pedicel and 

 ovary glabrous: Style trifid to the base, the branches bifid one-half 

 their length; capsule glabrous, tricoccous, cocci rounded; seeds 

 triangular-ovoid, i x..8 mm., blackish with yellowish angles, apex acute,
