flowers (Pl. V. figs. 1, 2) of Sararanga sinuosa consist of a 
rudimentary perianth and of a gynaeceum, no traces of an 
androecium being discernible. The perianth has the shape of 
a flat, sinuously bent saucer. It is, even in a young state, rather 
fleshy and thick (PI. V. figs. 3, 14). It is closely adpressed to 
the base of the gynaeceum, exactly following its sinuous windings, 
but not adnate to it. The margin is entire and there is no 
venation visible to the naked eye, though a microscopic exami- 
nation reveals the presence of generally simple vascular bundles 
which radiate from the base. The gynaeceum consists of a 
fleshy, roughly semi-globose or subglobose body—about 6 mm. 
in diameter—-which is sinuously lobed, as shown in PI. V. 
figs. 1, 2, 6-8. The surface is smooth in a fresh state, and the 
colour white. The stigmas consist of small and dark wart-like 
protuberances, more or less round or slightly reniform. They 
are very numerous, upwards of 70 or 80 in one flower, and so 
arranged in a continuous Jine that the line exactly follows the 
branching of the gynaeceum, always keeping strictly to the 
dorsal ridge of the main body as well as of the lobes ; but as it 
runs out almost right to the end of each lobe and returns 
strictly parallel to itself till it reaches the next sinus, and so 
on, it forms the sinuous double row of stigmata which is so 
remarkable a feature in the flower and fruit of Sararanga. 
Where the stigmata show an approach to horseshoe shape the 
sinus ig always on the inner side (PI. V. fig. 12), so that the 
sinuses of two opposite stigmata face each other. Within this 
double row of stigmata there isa very shallow, and sometimes 
quite obscure depression, in which—with the aid of a lens— 
minute pores (PI. V. fig. 12, 13) may be seen, from which some- 
times a more or Jess obscure groove extends towards the

verse section through two opposite stigmas (Pl. V. fig. 9; 
Pl. VI. fig. 18) shows that there is one ovary cell below each 
of them and about equally distant from the top and the bottom 
of the gynaeceum, containing a single anatropous ovule (PI. VI. 
fig. 22). This is born on a rather stout funicle, which springs 
from the inner basal angle of the cell. Its structure is essentially 
the same as in Freycinetia javanica (see Solms-Laubach, in Bot.
