Ridley writes that the Rattan of this Korthalsia, known under the name of 
"Rotang Sumut” (or the Ant-Ratian) is valued on account of its small size and 
strength. In Sarawak, however, the Rattan is considered of bad quality and 
receives the name of *Rotang Undang.” 
Osservations.—This is \one of the characteristic myrmecophilous or Ant-harbour- 
ing Korthalsias, and its inflated ocreas a species of Camponotus in Borneo. and the 
Iridomyrmex hospes in Sumatra, make their abode, penetrating inside through holes, 
made by the ants themselves, in the wall of the ocrea, or by means of erosions 
on their margins (see Beccari, Malesia, ii, p. 63, 68). 
K. scaphigera is characterized by its slender stem; by the leafsheaths having 
small but well formed elliptical inflate ocreae, more or less armed with short 
conical or tuberculiform prickles; by the leaves having few cuneate ‘leaflets, more 
or less glaucescent beneath, and only those of the uppermost leaves ansate, the 
others attached to the rachis by means of an acute base, having a callosity (or 
nectariferous cushion ?) in the axillas; by the tomentose spikes; by the ovoid, 
mueronate and pungent fruit, and by the ruminated seed. 
t is a variable plant. The sheathed stem in a specimen of Scortechini from 
Perak is 17 mm. in diameter; in one from Palembang in Sumatra it is only 
5 mm. The leaves vary in the size and shape of the  leaflets, more or 
less elongate or even rhomboidal. The dimensions of the fruit given above are 
taken from Ridley’s No. 6272. In King’s Collector No. 3503 from Perak, the 
fruit is considerably larger, measuring 22-25 mm. in length and 17 mm. in 
diameter, and the seed is 15 mm. long and 11 mm. across; otherwise the 
structure is the same as in the other. 
Pirate 64.—Korthalsia scaphigera  JMart.—Portion of the stem and an entire 
leaf; the intermediate part of the plant from one of Scortechini’s specimens 
collected in Perak (Herb. Beccari); partial inflorescence, bearing spikes with fully 
developed flower buds. From Goodenough’s No. 1704 in Herb. Beccari. 
Pirate 65.—Korthalsia scaphigera Mart.—An almost entire fruiting panicle and 
the upper part of an adult plant. From Ridley’s No. 6272 in Herb. Beccari. 
PLate 66.—Korthalsia scaphigera Mart.—Portion of the stem with an entire 
leaf from the upper part of the plant, and a branch of the fruiting spadix; very 
young plant with primordial leaves. From Beccari P. B. No. 2493. Fruits and 
seeds, one seed cut longitudinally through the embryo; from King’s Collector 
No. 3503. Sa
