ones gradually shorter, not very deeply 2- or 38-lobed at the 
apex, the lobes shortly 2-toothed. Spadix large, divided into 
several, spirally alternate, strongly flattened floriferous branches, 
the lower of which are 30 to 40 cm long, and the upper gra- 
dually shorter. The fruits are exactly distichous throughout 
the entire length of the branches, small, obovoid, apex round, 
base (in the part included in the perianth) acute, 15 to 17 mm 
long and 9 mm thick. Seed oblong, rounded above, 10 to 11 
mm long, 7 mm thick, with the areola of the embryo very 
slightly oblique; vascular branches of the integument almost 
simple. Fruiting perianth shallowly cupular, very slightly 
broadening at the mouth, 2.5 to 3 mm high, 5 mm broad. 
This was first described from very incomplete material. The 
various specimens with fruits, received later, correspond very 
well to the typical ones, which had flowers only. All the her- 
barium specimens I have examined have acquired a uniform 
yellowish tint on both surfaces, are not very rigid but rather 
flexible, and look as if they had been rather herbaceous in the 
living plant. 
22. PINANGA SIBUYANENSIS Bece. sp. nov. 
Inter majores, subelata, caudice ad 9 m longo, 15 cm diametro; 
frondium segmentis numerosis, aequidistantibus, late ensifor- 
mibus, usque ad apicem rectissimis, utrinque virentibus, subtus 
paullo pallidioribus, validissime bicostulatis, apice inaequaliter 
bifidis; spadicis ramis numerosis, spiraliter insertis; fructibus 
3-seriatis, majusculis, 25 ad 28 mm longis, 15 ad 17 mm latis, 
ovato-ellipticis, utrinque aequaliter attenuatis; semine late ovato, 
superne rotundato; fovea embryonali nonnihil obliqua; integu- 
menti ramis vascularibus numerosis, undique reticulatim anas- 
tomosantibus ; perianthio fructifero. ad faucem nonnihil coarctato.

_ This is allied to Pinanga insignis, but is apparently a smaller 
plant yet with larger fruits, and with the vascular branches 
of the integument forming a network all around the seed.

MINDANAO, Davao District, Todaya, Elmer 11238, with the local name 
tangalo. : 
A fine but almost useless palm, very widely spread in the 
Malay Archipelago and in the Moluccas, but probably of foreign 
origin in the Philippines.
