NEW OR NOTEWORTHY BORNEAN PLANTS. 169 
An erect, nearly glabrous shrub 2 to 3 m. high, the branches 
and branchlets terete, reddish-brown, glabrous or the younger 
branchlets obscurely pubescent. Leaves oblong to oblong-elliptic, 
12 to 18 cm. long, 4.5 to 7 cm. wide, chartaceous to subcoriaceous, 
entire, subequally narrowed to the acute base and the shortly 
obtuse-acuminate apex, brownish-olivaceous, somewhat shining and 
minutely verruculose on both surfaces when dry, the upper surface 
glabrous, the lower surface glabrous or slightly pubescent; lateral 
nerves about 8 on each side of the midrib, distinct, ascending at 
an angle of about 45°,somewhat curved, obscurely and laxly anasto- 
mosing, the reticulations obsolete or nearly so; petioles 5 to 10 mm, 
long, deeply channelled on the upper surface. Flowers white, axil- 
lary, solitary or somewhat fascicled, their pedicels 3 to 4 mm. long, 
slightly pubescent, 2-bracteolate, the bracteoles ovate, pubescent, 
about 1.2 mm. long. Sepals 5, free, imbricate, somewhat pube- 
scent, orbicular to orbicular-obovate, rounded, about 2.2 mm. in 
diameter, minutely puncticulate. Petals 5, united into a cylindric 
tube in the lower 2 mm., externally ferruginous-pubescent in the 
lower half, or on those parts forming the limb which are exposed in 
bud, those portions of the petals valvate, oblong, about 3 mm. iong, 
each petal cleft into 2, oblong, glabrous lobes, the lobes truncate- 
rounded, inflexed in bud, 3 mm. long, 1.2 mm. wide, spreading at 
an angle of about 45° in anthesis. Stamens 5, alternate with the 
petals, inserted near the apex of the corolla-twbe, their filaments 
1 mm. long; anthers ovoid, somewhat acuminate and minutely 
apiculate, basifixed, 2-celled, about 1.8 mm. long, opening by lateral 
slits, the connectives stout, broad, narrowed upward. Disk O or 
very obscure. Ovary superior, globose, glabrous, 1-celled with 3 or 
4 erect basal ovules; stigma sessile, broadly conical, somewhat sul- 
cate, about 1 mm. in diameter. Fruit (not quite mature) oblong- 
ellipsoid, glabrous, 8 to 9 mm. long, 1-celled, 1-seeded, the peri- 
carp rather thin, the seed somewhat fleshy, the calyx lobes persistent 
but not accrescent. 
British North Borneo, Batu Lima, near Sandakan, and at 
Marutai, Ramos 1454 (type), Wood 453, flowering in October and 
with immature fruits in June. Mr. Wood’s specimen is labelled as 
‘coming from back of the mangrove swamps, while Ramos notes 
it occurs in forests and in open places at low altitudes. This pro- 
posed new genus presents certain characters intermediate between 
Icacinaceae and Olacaceae and might with almost equal propriety 
be placed in either family. It is at once distinguished from all 
hitherto described genera in these families by its conspicuously 
cleft petals, the relatively large lobes being inflexed in bud and 
spreading at an angle of about 45° in flower. In its stamens being 
alternate with the petals it differs from most representatives of the 
Olacaceae, while in its erect basal ovules it differs frorh most or all 
of the Icacinaceae. I have placed it tentatively in the Olacaceae.
