priekles along the ventral side only, especially near the bases of the petioles. 
Ocreae having a short permanent coriaceous base, armed with some prickles on the 
ventral side, and lengthened above into a closely sheathing brown, membranous 
appendage 2—4 cm. long in the lower leaves, and shorter in the upper ones; this 
appendage is later more or less disintegrated into a fibrous, perishable net. Inter- 
mediate leaves of the adult plant 40—50 cm. long in the pinniferous part, ending in 
a somewhat shorter and slender clawed cirrus; petiole very short, 2—4 cm. long, 
broadly concave above, rounded beneath, furnished with a distinet callus and 
transverse rima at its axilla; rhachis armed with scattered usually solitary, claws. 
Leaflets 5—6 on each side of the rhachis, alternate, rigid, thinly coriaceous, green 
and almost glossy above, whitish beneath in newly expanded leaves, but later only 
slightly paler than above, somewhat asymmetrically cuneate-rhomboidal, 15—18 cm. 
long, 5—7 cm. wide, their upper margins irregularly undulate and erose-toothed, the 
secondary teeth very minute and acute; the apex acute or somewhat produced ; 
main nerves 7—9, slender, the central one more prominent than the others; transverse 
veinlets numerous, very fine, continuous and pellucid; the ansae are conspicuous, 
10—12 mm. long, minutely rusty-furfuraceous, thickish and swollen at the base. 
The uppermost leaves, especially those nearer to the inflorescence, are smaller than 
the intermediate, have a shorter cirrus, and smaller leaflets (8—10 cm. by 3:5—4 em. 
or less), and are more shortly cuneate, or more regularly rhomboidal. Inflorescence 
about 50 cm. long, twice branched, but having only 2—3 primary sinuous branches 
divided into only 2—3 secondary branches. ‘ Spathes  elongate-tubular, slightly 
infundibuliform, closely sheathing, unarmed or at times slightly spinulous, their 
mouths obliquely truncate and slightly produced at one side into a triangular acute 
point ; the secondary or spike-bearing branches are short (10—15 cm. long) and bear 
only 3 or at most 4 spikes. The spikes have a glabrous appearance, are attached 
by means of a slender, flattened pedicellar part to the bottom of their respective 
spathes, and have their bases very slightly exserted from these, are alternate, spread- 
ing, flexuous, 6—8 cm. long, 5 mm. in diameter, not taking into account the flowers, 
and 9—10 mm. with them; spathels broadly triangular, concave like a swallow's 
nest, and suffulting the bases of the flowers, obtuse, membranous, strongly striately 
veined, free (not connate by their margins), considerably produeed beyond the wool 
of the flower-braeteoles so that the spikes assume a glabrous appearance; the flora] 
bracteoles are almost entirely reduced to dense tufts of short woolly hairs. Flowers 
arranged in 7 longitudinal series, dipping into their woolly bracteoles by the lower 
part of the calyx only ; are 4 mm. long and 3 mm. broad, obovoid, obtuse; the 
calyx is cyathiform, not or but slightly attenuate at the base, strongly striately 
veined, parted down to only a little above the base inio 3 ovate obtuse lobes; the 
corolla is twice as long as the calyx or a little less, or divided for two-thirds of its 
length into three ovate cymbiform segments, striate externally; the stamens have 
the filaments short and thick, subulate at apex, united below to the entire urceolate 
base of the corolla; anthers ovate-sagittate, acute; ovary ovoid. narrowing above 
io a short sulcate conical acute style reaching only to the base of the anthers ; 
stigmas very minute, punetiform. Fruit globular or globular-turbinate, a little longer 
than broad, 16—18 mm. long, 14—15 mm. broad, rounded at the base, the apex 
very slightly depressed and bearing the very minute remains of the stigmas in the
