 2-6 unc. longa, ^-| lata, substellatim patentia, petiolata, margine integra v, obscure 

 sinuata, glabriuscula, basi tantum pills albidis tomentosa, pagina superiore saepius 

 lacunosa. Rami 3-6, omnes e cello orti, diametro pennae passerinae, 3 unc. ad pe-

 subacutis. Capitula parva, alba, \ unc. lata. Bracteolae 3, late ovatae, obtusae, peri-

 thiformis, 5-dentatus, dentibus 2 lateralibus tantum 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 lilie scapes.

Most nearly allied to /. 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 /. interrupta, Benth., but the
