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 23 in. in diam., with pedicels as described above,) and an utterly 
different plant collected in Ceylon by Macrae, in which the leaves are 4-1} 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 ZL. aurantiacum, Dalz., 
although the flowers are stated to be white on the label. See Hook. fil. Fl. Brit. 
Ind. iv. 182. 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.— NV. E. Br. 
2. L. abyssinicum, N. E. Br. Leaves 11-4 in. in diam., orbi- 
cular, with a deep acute sinus at the base, very thin and membranous. 
False petioles #-14 lin. thick, bearing 10-12 or more flowers in 4 
cluster, close to the leaf-blade. Pedicels 4-1 in. long, }—} lin. thick. 
Sepals 1}~-2 lin. long, oblong-lanceolate, subacute or obtuse. Corolla 
not seen. Fruit globose, exceeding the sepals, 10—20-seeded. Seeds
