Drescription.—Large and high scandent. Sheathed stem 2—3°5 cm. in diameter. 
Leaf-sheaths thick and woody, more or less split along and disintegrated into a 
fibrous net on the ventral side, very sparingly armed with short conical prickles or 
almost smooth; the surface is dull, and very slightly rough to the touch. Ocree 
of old leaves closely sheathing, truncate, short (1—2 em. long), more or less disin- 
tegrated into fibres on the ventral side, unarmed or nearly so, apparently produced 
into a perishable membranous and fibrous “limb in young leaves. The leaves of 
the adult plant are large, have numerous leaflets, and end in a long robust cirrus ; 
the petiole is flattened, flattish above, has very obtuse edges, is convex and armed 
with few robust claws beneath, and is furnished with a conspicuous callus at its 
axilla; the rhachis is armed below with robust claws, at first single, then binate- 
` higher up tri-nate, and in the cirrus 5-nate or half-whorled. The leaflets are at 
first whitish beneath and finally slightly glaucous or only somewhat paler than above; 
those of the lower part of every leaf are cuneate-rhomboidal, about 30 em. long, 
10 em. broad; the intermediate are broader, rhomboidal or trapezoidal, 20—25 cm. 
long, 18—20 em. wide, have 9—11 main nerves, which end in as many obsoletely 
double-toothed, not produced, broad, bluntish points. The anse are elongate, 10—20 
and at times up to 30 mm. long, thickish and wrinkled, and therefore in the 
living plant probably somewhat fleshy and subterete, very minutely rusty-furfurace- 
ous; the same kind of minute scurf covers the petiole and the rhachis in newly 
expanded leaves, but is _more or less deciduous afterwards, and the surface of those 
organs remains very minutely scabrid. The inflorescence, according to the plate 
given by Griffith, is large, the flower-bearing branches are short, and bear only 2—3 
spikes; the latter are 20 cm. long and 1 cm. broad, tomentose. but with the spa- 
thels very clearly visible or even considerably produced beyond the wool of the 
flower-braeteoles. Fruit 
Hanrrar.— The Malay Peninsula and probably also Sumatra. Griffith deseribed 
this species from specimens brought to him from a place called Kussan (or Kesang ?) 
near Malacca. Ridley says that it is common in Singapore at Bukit Timah 
‘(No. 10407 in Herb. Becc.) and in Johore at Kwala Sembrong (Ridley). To this 
species belongs, I think, a specimen collected in Selangor by Franz Keheding in 
1878 (Herb. Becc.) This specimen in ^" Malesia” II, 74 was considered to be 
K. laciniosa. | | a
