Description.—Small, erect. Sheathed stem 15-20 mm. in diameter. Leaf-sheaths (of 
the upper part of the plant) not or very slightly gibbous above, obsoletely longitudinally 
eostulate, usually armed with solitary, scattered, flat, laminar, 10-15 mm. long, 
subulate, brown-spadiceous or blackish, ascendent or deflexed spines.  Ocrea very short, 
exactly horizontally truncate. Radical leaves not cirriferous, considerably larger than 
the upper ones, about 2m. long in the pinniferous part and with an unusually long 
petiole which is terete and armed towards its base with seriate spines and smooth 
higher up or with straight dentiform prickles on the margins, and with a line of claws 
along the centre of the dorsum in the upper part. Leaflets very elongate, linear, 
tne largest 40-50 em. long, 15-20 mm. broad, subconeolorous on both surfaces, slightly 
narrowing to the base, where very suddenly backwardly plicate, acuminate from near 
the apex into a subulate tip, tricostulate above where the mid-costa is robust 
and acute, the side costae more slender and more closely spinulous especially 
towards the apex; on the lower surface the mid-costa alone very closely and finely 
bristly from the base to the apex, the side nerves slender and glabrous; the margins 
closely spreadingly, finely ciliate. Upper leaves of the flowering part of the plant, 
much reduced in size and quite different from the radical ones, cirriferous, 20-40 
cm. long. including the slender cirrus; petiole very short, 1-4 cm. long, flattened 
plano-convex, its margins acute, smooth or prickly, the dorsum armed along the 
centre with approximate small slender claws, which are solitary at first and become 
2-3-nate along the rachis and half-whorled on the cirrus; leaflets rather numerous, 
20-25 on each side, approximate, equidistant, very small, linear or linear-lanceo- 
late, 5-15 em. long, 4-5 mm. broad; on the upper surface the mid-costa alone 
usually carrying a few bristles; underneath the mid-costa very closely and minute- 
ly bristly; margins closely spreadingly ciliate. Spadices crowded at the apex of 
the plant, before flowering fusiform-elliptical, rather ventricose or fusiform-ovoid, 
rather shortly beaked, 12-25 em. long, inserted near the mouth of their sheaths, 
erect, supported by a short prickly or almost smooth pedicel; outermost spathe obso- 
letely 2-keeled, more or less covered with a very dark or tobacco-coloured scurfy
