longe petiolatis ovatis v. rhombeo-ovatis utrinque attenuatis obtusiusculis emarginatis glabris viridi-

densis viridibus; calyce bracteis fere triplo longiore; utriculis subglobosis apice acutiusculis valde

Albersia gracilis, Webb. et Berth. Phyt. Canar. vol. iii. p. 287.—Nomina vernac. Vitiensia, ** Driti” 
et “ Gasau ni vuaka."—4A 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, E. viridis.
