L. forbesianum, Griseb., according to the type specimens at Kew, was founded 

 upon the above-quoted specimen collected by Forbes (which has two leaves, respec- 

 tively 1 and 2h in. in diam., with pedicels as described above,) and an utterly 

 different plant collected in Ceylon by M.icrae, in which the leaves, are ^-1^ in. 

 in diam., and the flowers in pairs at the nodes of an elongated stem, or, in small 

 plants grown in very shallow water, among the axils of the leaves. Macrae's dried 

 specimens (No, 87) do not differ in any way from those of L. aurantiacum, Dalz., 

 although t)io flowers are stated to be white on the label. See Hook. fil. Fl, Brit. 

 Ind. iv. 132, Two very different plants having thus been combined by Grisebach 

 under one description, which agrees with neither of them, it appears better to discard 

 the name L. forbesianum altogether. — N. E. Br.

 cular, with a deep acute sinus at the base, very thin and membranous. 

 False petioles j-lj lin. thick, bearing 10-12 or more flowers in a 

 cluster, close to the leaf- blade. Pedicels \-l in. long, J-^ lin. thick. 

 Sepals 1 A- 2 .lin. long, oblong-lanceolate, subacute or obtuse. Corolla 

 not seen. Fiuit globose, exceeding the sepals, lO-20-seeded. Seeds
