K. macrocarpa. KORTHALSIA. 148 . 
K. robusta. Closely allied: to K. robusta are K. squarrosa and K. macrocarpa, especially 
the latter; but K. robusta is distinguishable from both in having the style closely 
enwrapped by the thickened tube of the corolla and not protruding with its 
apex during the anthesis beyond the opening in the centre of the ring formed by 
the connate bases of the filaments; whereas in the other two, but more especially 
in K. macrocarpa, the style is .loose in the tube of the corolla, and with the 
apices of the stigmas reaches to about midway of the anthers.

Descriprion.—Scandent and rather large. Sheathed stem of the flowering plant 
2—2'5 cm. in diameter. Leaf sheaths armed, especially on the dorsal side, with 
scattered, very slender, blackish, lustrous spicule, 5—12 mm. long, resting on a 
tuberculiform base. Ocree extraordinarily long (20—40 cm.), rigid, thinly coria- 
ceous or subpergamentaceous, not inflated, and having the shape of a narrow and 
long horn, or of an elongated ass’s ear, gradually acuminate to an obliquely 
trancate point, unclosed all along their ventral side, so as to be incompletely clasp- 
ing, and covered all: over with very slender, scatttered spicule similar to those 
occurring on the leaf sheaths but very often longer. Leaves large; those of the 
upper part of the adult plant are cirriferous, have the petiole rather elongate (20—30 
m., long 7—8 mm. broad), more or less prickly, complanate, flat above, slightly 
convex beneath, and with sharp edges; the rhachis is armed beneath with scat- 
tered, black-tipped claws; the leaflets are numerous, green above, white beneath, 
very conspicuously ansate; the lower leaflets in every leaf are considerably longer 
than broad, oblong cuneate or cuneately-rhomboidal, the blade alone being 20—25 
em. long, 5—6 em. broad; the intermediate and upper leaflets are more regularly 
rhomboidal than the lower, not much longer than broad (15—18 em. long, 10—12 em, 
broad); all have 11—13 radiating main nerves, and the upper margip irregularly and 
rather sharply erose-toothed, the teeth terminating the main nerves being very 
acute and often aristate. The leaflets on the leaves from young plants are narrow 
and relatively longer than those of the adult plant, and are more distinctly chalky 
white underneath; their ansce are always unusually long and slender, as much as 
5—6 cm. in length, and not more than 2—3 cm. in breadth; in the uppermost 
much reduced leaves the anse are still longer, and more slender, and being 
strongly flattened, probably cause the blade to assume a quivering motion, as is the 
case with the leaves of Populus tremula. The inflorescence is apparently composed 
of several approximate primary branches; one of these seen by me is 25 em. 
long, is divided into 4 secondary branches, very short and approximate, each 
branch bearing 2 spikes, the whole forming a very eompact, recurved panicle. The 
spathes are large, have a very short tubular basilar part, and a very broad, 
strongly concave embracing ovate acute or acuminate dry rigid papyraceous limb, 
are cinnamon brown internally and light coloured, glabrescent, smooth or slightly
