A very extensive genus, of which the species are most abundant in the intertropical regions, — They 
are not susceptible of being divided into well-defined sections. The following are Polynesian species nob 
vet found in Viti, viz.:—l. P. fissidentoides, Tayl. Lond. Journ, of Bot. 1846; Gottsche, Lindenb. et Nees 
Syn. Hepat. p. 636.—Sandwich Islands (Menzies !)—Compared by Taylor to P. bursata. P. Vitiense may 
be the complete state of P. fissidentoides, but it does not suggest any comparison with P. bursata, with 
which Taylor contrasts it. 2. P. bialata (sp. nov.), Mitt,; ram graciles, subsimplices, infra perianthiam
