Description.—A large species. Sheathed stem 2—3 cm. in diameter. ar uei 
distintegrating along the ventral side into embracing fibres, otherwise very thick 
and woody, quite smooth or at times more cr less armed, especially at the base of 
the petioles and along the dorsum, with very short straight horizontal or slightly 
deflexed scattered spines having a very thick base. The ocre@ are elongate, 
10—15 em. long, and prolonged above into a liguliform limb. are unarmed, or fur- 
nished at most with only a few spinules, are originally dry and thinly membran- 
ous, but very soon become entirely ragged and disintegrated into filaments, especially 
on the ventral side, so much so that in old leaves the ocree may appear to be 
. wanting. Leaves large, those of young plants terminating in a fiabellate leaflet; 
those of half grown plants have a slender cirrus, and a rather elongate 20—25 
em. petiole, whereas those of the full grown and fertile plants have the petiole 
short, the pinniferous part about 1°5 m. long, ending in a very powerfullv-clawed 
cirrus about as long, and bearing about 10 leaflets on each side of the rhachis. The 
petioles in no case have any distinct callosities at their axillas, are broadly chan- 
nelled above, convex and unarmed below. and are more less irregularly beset on 
their margins, especially in their basal part, with straight spines, the largest of 
which are 10—12 mm. long. The rhachis is armed at the sides below (but not 
along the centre) with single robust claws; in some leaves, apparently belonging 
to young plants, the petiole is quite unarmed. The leaflets are very variable in shape 
and size, from considerably longer than broad or euneate-oblong or obovoid-cuneate 
to broadly rhomboidal or trapezoidal and about as long as broad; they are green 
above and more or less glaucous and in newly expanded leaves are distinctly 
mealy-white beneath; they are rigidly-papyraceous, have 11—15 equally strong 
main, radiating nerves, ending in as many double-toothed, sharp, subulate points, the
