interdum paniculatas congestis ; bracteis carinatis, concavis, persistentibus.—Aldersia, Kunth, Flor,

longe petiolatis ovatis v. rhombeo-ovatis utrinque attenuatis obtusiusculis emarginatis glabris viridi- 
bus; spicis ascendentibus gracilibus obtusiusculis subflexuosis; floribus brevissime pedicellatis sub- 
densis viridibus; calyce bracteis fere triplo longiore; utriculis subglobosis apice acutiusculis yalde 
rugosis.—Chenopodium caudatum, Jacq. Coll. vol. ii. p, 235, et Icon, Rar. t. 344, Amarantus ale- 
raceus, Lam. Dict. vol. i, p. 116, non Linn, A. gracilis, Desf. Cat. Hort. Paris, ed. i. p. 43, 
Albersia gracilis, Webb, et Berth. Phyt. Canar. vol. iii. p. 287——Nomina vernac. Vitiensia, “ Driti” 
et  Gasan ni yuaka”’—A common roadside weed throughout Viti (Seemann! n. 368). Also col- 
lected in Tahiti (Banks and Solander!), the Tongan Islands (Capt. Cook !), and Oahu, Hawaiian 
group (Barclay !). Moquin-Tandon saw it also from New Caledonia (Labillardiére). It is com- 
mon in Australia, India, and tropical America; and I expect that, in determining the Tahitian col- 
lections, it has been confounded by several authors with the allied, perhaps identical, EZ. viridis.
