Hab. Brazil ; in the vicinity of Rio Janeiro. 

 6. Jussicea octofila, DC. 



Jussicea octofila, DC. Prodr. 3, p. 57 ; Benth. Bot. Voy. Sulph. p. 92. 



Hab. Pern, near Lima. Also at Callao : a nearly glabrous variety. 



The latter variety, in a still more glabrate form, likewise occurs 

 in the Sandwich Islands, at Oahu (but apparently is not in our 

 collection) ; and Walpers, in Rel. Meyen. p. 326, has referred it to 

 J. octoriervia, Lam. ; but the ovary tapers at the base into a slender 

 pedicel, and is usually bracteolate. Probably the two species may be 

 united.
