E. mayor. | EUGEISSONA. 205 
The large, long, straight aerial roots when not, completely lignified, can be 
readily split longitudinally, and the. fibro-vaseular bundles separated. ‘The Dyaks 
in Sarawak profit by this peculiarity to obtain from the aerial roots fine and 
neatly finished very tough filaments, about 1 mm. thick and 2—3 m. long, with 
which, when dyed in various colours, small. bags (tambuks), necklaces, bracelets 
etc., are made.. From the largest and hardened roots very fine walking. sticks are 
also made. 
OssERVvATIONS.—]t is characterized by its trunk rather high, propped by long 
aerial roots, and rendered trigonous by the 3-seriate permanent bases of the 
leaves ; by the’ leaflets being bristly on the mid-costa; by its faleate flowers 
10 em: long; by the corolla having a very short (only 18—20 mm. in length) 
tubular basal part; by its numerous (50 or more) stamens; by the fruit 10—10'5 
em. long, 6 em. across, obovoid and veryvobsoletely trigonous, and very suddenly 
and shortly stoutly rostrate, and having 12 internal dissepiments; by the scales 
very acuminate. l'5 mm. wide; and by the thickness of its pericarp, of which the 
mesocarp measures 7 mm. and the endocarp 3 mm. 
PLATE 118.—Eugeissona insignis Bece.—Entire flower-bearing branch; one middle 
sized fruit entire; vertical section through the seed of one of the largest fruits; 
the lower half of a fruit transversely cut. From Beccaris P. B. No. 2010. 
6. Ev@rissona MAJOR Bece. Malesia iii, 58. 
Descriprion.—Fruit large, 13 em. long, 10 cm. across, ovoid, regularly circular 
in transverse section, almost equally broad at both ends, flattish at the base, 
very slightly depressed, and very suddenly contracted above into a broad, short 
and obtuse mammilliform rostrum, only about 12 mm. high. Seales extremely 
numerous, small (the largest 15 mm. broad at their bases) and slightly depressed 
or faintly grooved in their postcious part, and produced into lighter, elongate, 
acuminate apices. The pericarp is very thick, on the average 16—17 mm. in 
thickness in a transverse central section; the endocarp alone is 3 mm. thick ; 
the cavity is divided very regularly into 12 incomplete dissepiments, of which 
the three principal penetrate very deeply, almost to the centre of the seed, and 
are obtusely bilobed in transverse section at their internal end, while three are 
somewhat shorter, and six smaller still. The seed is 6 cm. in diameter and 
marked by as many deep furrows as there are ‘dissepiments. Other parts 
unknown. i 
HaBrrAT.— Borneo, collected by Teysmann on the Kapuas. 
Osservations.—It is related to Æ. insignis from which it differs in its much 
larger and shorter rostrate fruit, but especially in its greatly thicker  pericarp. 
Portions of leaves and some flowers (not referable to any one of the species of 
which these parts are known) collected by Hallier at Liang-gagang in Dutch 
Borneo, during the Expedition, 1893-94 (No. 2627 in Buitenzorg Herbarium) apparently 
belong to this species. The flowers and the leaves of E. major not being known. 
and Hallier's specimens wanting the fruit, a sure identification of these is, of 
course, impossible. It may even be that the  Eugeissena of Liang-gagang belongs 
to a species distinct from Æ. major, and as yet undescribed. 
i Prate 115 (C.)—Eugeissona major Becc.—One of the fruits collected by 
Teysmann on the Kapuas; transverse median section of the same.
