DrscRiPTION.— lufted, gregarious. Stem erect, 4-5 m. high, with internodes 
when divested of the sheaths 3-4 cm. in diam., green, smooth, 6-10 cm. long.  Leaf- 
sheaths not flagelliferous, broadly opened on the ventral side (not completely tubular) 
and gradually passing into the petiole, densely and irregularly armed with long, large, 
flat and laminar spines.  Ocrea very large, in full-grown leaves longitudinally split 
on the ventral side into two large oblong auricles (one on each side of the petiole), 
9-7 cm. long, obtuse, densely covered with more or less distinct and transversely 
seriate lamelle, and crested with dark, rigid, very numerous, confluent bristles, Leaves 
not cirriferous, very large, 3-5 m. in length; petiole sub-cylindric, rigid, erect, 
very long, armed with rather remote whorls or half-whorls of straight, 2-3 cm. long 
flat, elastic and deflexed spines, which are light at the base and dark-tipped; inter- 
mingled with these are other spines, solitary or disposed in smaller and incomplete 
series; rachis acutely angular and with two flat side-faces above, rounded beneath 
where it is armed in its first portion with half-whorled, and near the summit with soli- 
tary, laminar, deflexed, straight, never claw-shaped spines ; leaflets very numerous, pale- 
green when dry, nearly shining above, dull and hardly paler beneath, equidistant, 
alternate or subopposite, 5-7 cm. apart, elongate-ensiform or narrowly lanceolate, 
subulately acuminate, somewhat alternate and deeply backwardly plicate or doubled at 
the base; their mid-costa stout and raised above, bearing mainly near the apex, on 
both surfaces, a few not very long spiny bristles; secondary nerves fine, rather 
numerous, inequidistant, not prominent, but frequently very distinct, naked on both 
surfaces; transverse veinlets very fine, crowded and interrupted; margins acute, 
Spinulous-serrate from the middle upwards; the largest leaflets, the mesial, 60-75 cm. 
long, 3:5-4 cm. broad, the upper gradually shorter and less acuminate, or almost
