BECCARI. 
There is little or no doubt that this is Caryota tremula of Blanco. That 
author, however, describes the female flowers of this palm as having 6 sepals, 
probably because he considered the bracts as sepals. 
Arenga tremula is very closely related to A. AmbOng, from which it differs 
by the male flowers having a rounded top, and more numerous stamens ; but 
specially in its oblong, not spherical fruit. 
ORANIA Zipp. 
Orania decipiens Becc. sp. nov. 
Robusta, caudice circiter 8 m longo, 24 cm diametro. Frondes 4-5 m 
longae, segmentis supra nitidis, subtus albicantibus, praecipue prope basin 
plurieostulatis ; majoribus usque ad 1 m longis. Spadices ampli, du- 
plicato-ramosi, longe pedunculati, ramulis floriferis gracilibus, inferioribus 
40-45 cm longis, superioribus brevioribus, e basi- 3 mm crassa sursum in 
acumen tenue leviter et regulariter “zig-zag” sinuosum sensim attenuatis. 
Flores in ramulorum dimidiam inferiorem partem terni, intermedio 
foemineo, alaribus masculis, caetero geminati et tan turn masculi. Fructus 
globosi, basi nonniliil attenuati, ibique subacuti, 40-42 mm longi, 35-37 
mm lati ; epicarpio fragili, tenui ; mesocarpio 3-4 mm spisso, fibris 
numerosis crassis, fere osseis, in superficie endocarpi erectis, praedito; 
endoearpio lignoso, tenui, basi paullo producto et obtuse apiculato ; semine 
globoso, basi paullo explanato, 23 mm lato; embryone supra medium 
locato; albumine osseo, intus pleno. 
Stems 8 m high and 24 cm in diameter. Leaves large, 4 to 5 m long 
(Merritt), apparently very similar to those of 0. pliilippinensis. Leaflets 
almost shining above, dull and whitish beneath, with the mid-costa very 
robust accompanied on each side by 3 or 4 other minor costae, and with 
several secondary nerves between these; the median leaflets the largest, 
up to 1.5 m long, 6 cm broad. Spadices large, twice branched, with 
a robust, and at its base 7 to 8 cm thick, peduncular part; the ultimate 
divisions or flowering branclilets are slender and of these the lower are 
40 to 45 cm long, the upper shorter, 3 mm thick at the base and from 
here gradually diminishing to a slender, and slightly but regularly, zig- 
zag-sinuous tip. The flowers are 3-nate in the lower half of the branclilets, 
and here the flower in the center is female, those at the sides male ; 
upward only geminate male flowers are to be found. Fruits spherical 
in their upper part, slightly prolonged downward into a blunt and slightly 
gibbous point at their bases which gives them a subpyriform shape, 40 
to 45 mm long and 35 to 37 mm broad; epicarp thin and brittle ; mesocarp 
3 to 4 mm thick, full of numerous, short, almost bony fibers, which are 
erect in respect to the surface of the endocarp; this is very thin and 
woody, on the whole spherical and like the general form of the entire 
fruit slightly prolonged at the base into a very obtuse point. Seed 
globose, with a slightly flattened base, 23 mm broad; the embryo is placed 
rather far above the middle; albumen bony, solid throughout. The base
