FLORA VITIENSIS. 143 
trorsum piloso-scabras producta,—Herbe ut plurimum annus; caule 4-gono v, tereti, seepius opposite 
ramoso, foliis oppositis, supremis interdum alternis, indivisis, partitis y. sectis, lobis incisis v. ser- 
ratis, capitulis plerumque flavis rarius radio albo, rarissime corollis omnibus purpureis. 
Bidens paniculata, Hook. et Arn, Bot. Beech, p. 66, from Tahiti, is probably identical with Bidens 
lantanoides, A. Gray in Proceed. Amer. Acad, vol. v., and certainly identical with B. fruticosa, DC, Prodr. 
vol. v. p. 596. n, 12; and Coreopsis fruticosa, Sol, Prim. FI. Tus. Pacit. p. 296, from Tahiti, of which authentic 
Specimens, agreeing with his description, are preserved at the British Museum. I subjoin Solander’s 
detailed description :— ;

impari-pinnatisectis, superis 3-sectis, ommium lobis glabriusculis ovatis acutis serratis vix decurren-

and waste places all over Viti (Seemann! n, 270). Also collected in the Tongan Islands (Forster !), 
Kermandec Islands (M‘Gillivray !), New Zealand, America, and Asia. 
B, leucantha, Willd., is regarded by most authors, following Schultz-Bip., as a variety.

lanatis oblongis ovalibusque in petiolum attenuatis repando-dentatis; scapo gracili nudo; involueri

rimis, disci sterilibus.— Mountains of the Macuata coast of Vanua Levu (U.S, Expl. Exped.). 
“ Amongst the largest species of the genus, the scape is 6-8 inches high, but the head is proportionally 
rather small, in fruit only 3 lines in diameter. The achenia are coarsely striated by 8 or 10 strong and 
salient ribs (in a manner unknown in other species), not beaked, but terminated by an epigynous disk 
about the size of the basal callus.”"—A. Gray.
