Radix majuscula, crassitie pollicis humani, descendens, ad collum foliosa. Folia plurima, 
2-6 unc. longa, i-i lata, substellatim patentia, petiolata, margine integra v. obscure 
sinuata, glabriuscula, basi tantüm pilis albidis tomentosa, paginá superiore sæpiùs 
lacunosa. Rami 3-6, omnes e collo orti, diametro pennz passerinz, 3 unc. ad pe- 
dales, superné di-trichotomé divisi, ad axillas foliosi, foliis oppositis oblongo-lanceolatis 
subacutis. Capitula parva, alba, j unc. lata. Bracteole 3, latè ovate, obtuse; peri- 
anthio j breviores. Perianthium basi villoso-barbatum, compressum, 11 lin. longum, 
segmentis subscariosis uninerviis medio maculis 2 viridibus. Tubus stamineus cya- 
thiformis, 5-dentatus, dentibus 2 lateralibus tantüm elongatis antheriferis. Ovarium 
globosum, compressum. 
Very unlike the other species in habit, though entirely coinciding with the 
genus Alternanthera in characters. It may be easily recognized by its singu- 
larly stout, fusiform root, radical leaves and slender branching stems, which 
appear like scapes. |

Most nearly allied to J. celosioides, L., of Columbia and the West Indies, 
but the leaves are much broader, the panicle patent, and the branches longer 
and more slender, the peduncles seldom if ever branched, and the flowers 
fewer and smaller. Also allied to the Mexican J. interrupta, Benth., but the
