BBCCARI, 



patule duplicato-ramosus, ramulis floriferis teretibus, vulgo 16-18 cm 

 longis, rigidis, craasiusculis, 2-2.5 mm apissis. Fructua spherici, stig- 

 niiitiiin residuifl fere exacte apicalibus apiculato-mucronati, 7 mm dia- 

 iiicti'o, perianthio concaviusculo minime pedicelliformi et bracteolis 

 eonspicuis, in eupulam brevem elevatis, sufl'iilti. 



A tree about 6 m high. Leaves large; leaflets equidistant, about 5 cm 

 apari on each side, nisi form. Blighl ly falcate near the end, very gradually 

 acuminate to m long Bubulate tip, papyraceous, shortly and Blightly nar- 

 rowed toward a not very acute base, Bubconcoloroufl on both surfaces, 

 unicostate, accompanied on each side of the mid-costa by two rather 

 prominent and distinct secondary nerves; the margins conspicuously 

 thickened ; at the base of the niid-costa on the upper surface is to be found 

 a small but very distinct glandular tubercle; the few leatlets seen by 

 me are apparently from the central part, these are 05 cm long, 3 cm 

 broad. The spadix is diffusely twice branched, the primary branches 

 being divided into 2 to 4 flowering branchlets; these are rigid, terete, 

 usually 15 to 18 cm long, 2 to 2.5 mm thick, bearing the flowers and 

 fruits spirally arranged. Fruit spherical, almost centrally mucronate- 

 apiculate by the remains of the stigmas, 7 mm in diameter. Seed 5,5 

 mm in diameter. Fruiting perianth very slightly concave. Floral bracts 

 forming a distinct shallow cup for receiving the base of the perianth. 

 The main axis of the spadix and branchlets very minutely scabrid. 



Luzon, Province of Cagayan, For. Bur. 11286 Klemme, April, 1008. local name 

 ilumiiuaca. 



Closely related to Hctcrospathc claia, but distinguished by its brandies and 

 branchlets being shorter, thicker, and more rigid, more deeply scrobiculate, while 

 the flower bracts form a distinct cup; by the fruit being less distinctly tuberculate 

 OS its surface, with the remains of the stigmas almost central; and by the perianth 

 being almost explanate and not subpedicellifonn.
