and almost entirely divided into three acuminate sepals; the 
corolla is about four times as long as the calyx; stamens 6, 
slightly shorter than the petals ; anthers linear-lanceolate, acute- 
apiculate ; rudimentary ovary represented by three filiform 
bodies as long as the stamens. Female flowers ovoid, obsoletely 
angular, rounded or flattish at the base, gradually attenuate 
above, acute, 13 to 14 m.m long, 7 mm broad at the base ; sepals 
broadly ovate, minutely ciliate, obsoletely keeled and slightly 
thickened below the bluntish or only slightly acute apices ; petals 
imbricate, broadened at both sides in their basal part, and sud- 
denly contracted into a thick, triangular, acute, valvate apex, 
the latter, 3 to 4 mm long, protruding entirely above the calyx ; 
ovary oblong, attenuate below; stigmas 3-gonous, spreading. 
Fruit very narrowly ellipsoid-oblong or subfusiform, diminish- 
ing considerably toward both ends, about 3 cm long, 9 mm in 
diameter. Pericarp thin, formed by only 2 or 3 layers of slen- 
der, parallel, complanate fibers, which render the surface of the 
dry fruit very finely striate longitudinally. Seed 13 mm long, 
6.5 mm thick. Fruiting perianth cyathiform, 12 mm high. 
Mindanao, Zamboanga District, Port Banga, in forests at about 20 meters 
above sea level. For. Bur. 9H1 Whitford & Hutchinson (specimen with 
fruits). Basilan, near the southwest end of Mindanao, Mount Balanting, 
at about 100 meters above sea level. For. Bur. Jt019 Hutchinson, February, 
1906, a palm 3 meters high, flowers white, fruit white; very common, local 
name pisa. 
Apparently also referable to A. Hutchinsoniana is Vidal U065 
(in Herb. Beccari), from Siassi, one of the smaller islands in 
the Sulu Archipelago, southwest of Basilan. 
The description above, as regards the fruit, is derived from 
Whitford & Hutchinson 914-1, otherwise from Hutchinson 4019. 
It is closely related to Areca Vidaliana, from which it differs in 
its smaller male and larger female flowers and, especially, in 
its larger fruits.
