not quite mature) perfectly spherical, 14 to 15 mm in diameter, with a 
very finely granulated surface, and with the scar left by the stigma quite 
lateral. Fruiting perianth 9 to 10 mm in diameter; the divisions of the 
cal} T x and of the corolla very broadly triangular and almost equal. 
Seed 
Necros, Gimagaan River, Whitford 1670, May, 1906. 
This species seems at first sight to be very similar to 0. gracilipes, from which, 
however, it differs in its broader leaflets, in the more slender branches of the 
spadix, in the perfectly spherical fruit with quite lateral (not subapical) remains 
of the stigmas, in the smaller perianth, and, occasionally, in the smaller scars 
left by the fallen fruits on the branchlets. 
Oncosperma horridum (Griff.) Scheff. 
Mindanao, District of Zamboanga, San Ramon, Copeland 1626. 
The above specimen differs but slightly from the plants growing in the Malay 
Peninsula, and in the islands of the Malay Archipelago. In the specimen I have 
seen, the spines covering the spathe are, however, criniform and much more 
slender than in the type; also the dry fruit has a thinner pericarp and the 
remains of the stigmas are less prominent. The fruits are 22 mm in diameter. 
Oncosperma filamentosum Bl. 
Palawan, Caranagan River, For. Bur. 3790 Curran, February, 1906, in river 
swamps. 
The specimens exactly correspond to those of the plant so common along the 
estuaries of the Malay Archipelago, the Malay Peninsula, Siam, and Cochincliina.

Growing in clumps, the trunk 10 m high and 12 cm in diameter, fruit red 
(Curran). The fruits are immature, 14 mm in diameter, slightly longer than 
broad. The plant seems to be more robust than that on which the species was 
established.

Cuming distributed this palm under No. 11/76 with flowers only; it lias been 
found again by A. Loiter at Montalban, Province of Rizal, Luzon (No. 7091 in Herb. 
Kew.), March, 1906, and on Mount Matulid at 1,200 m elevation, also in the 
Province of Rizal, in flower and fruit, March 15, 1906, (No. 7 051/ in Herb. Ivew.). 
It is a slender palm 1 to 2 m high, with a stem apparently about 2 
cm in diameter, sometimes stoloniferous ; the leaves are delicate, about 
80 cm long in the pinniferous part, with numerous very regularly set 
leaflets; petiole deeply channelled above; leaflets thinly papyraceous, 
narrow and elongate, very slightly falcate near the apex, which is very 
acuminate, and has a very shortly cleft tip; the medials are 25 cm long 
and 12 mm broad; the upper ones are gradually shorter but are not or 
only slightly narrower, while the lower ones are narrower but not at all 
or onlv slightly shorter. The spadix is small, about 45 cm long in one 
specimen, with a very lax panicle carried on a rather long straight 
peduncular part; the panicle is composed of a few, very spreading,
