Plants Collected in Paraguay. 57 



branched panicles, 4 styles, 5, sometimes 4, carpels which arc downy 

 and destitute of awns, and seeds somewhat irregularly 3-sided and 

 scarcely notched at the apex. S. rhomhifolia has 10 downy carpels 

 deeply grooved on the back, beaked at the apex by two short, smooth 

 awns. 8. spinosa, which bears no spines in my specimens to justify 

 the name, has 5 carpels with very short hispidly hairy awns or 

 horns, the faces marked by parallel veins, and smooth seeds which 

 have a minute projecting point at the ventral apex. S. urens, the 

 most peculiar of all these species in its general appearance, has only 

 3 styles, so far as I could discover in the fresh specimens. The 

 whole plant is clothed with long, fuscous, glandular hairs, especially 

 the calyx, which is greatly inflated, puffing out below in 5 folds and 

 terminating in 5 acute lobes ; carpels 5, small, smooth, beaked only 

 by two minute points ; seeds smooth, irregularly 3-sided ; flowers 

 yellow, massed in close clusters at the summit of the branches. The 

 long hairs on the edges of the folds and lobes of the calyx impart a 

 very nettle-like aspect to the plant, from which circumstance, I sup- 

 pose, the specific name originates.
