Description.—Slender and high scandent. ..Sheathed stem about 15 mm. in 
diameter. ^ Leaf-sheaths cylindrical, not or very slightly gibbous above, densely armed 
with very unequal, scattered, rigid, slender, grayish, 2—3 cm.. long, needle-like 
spreading or. deflexed spines, intermingled with others very , small and only a 
few millimeters long; the mouth of the sheaths is. obliquely truncate (not produced 
into an ocrea), armed with ascendent spines similar to those of the body of the 
sheaths and with narrow membranous borders produced into an axillary short 
triangular acute ligula. Leaves about 75 cm. long in the pinniferous part; 
the petiole 5—15 or more em. long, 7—8 mm. thick, spinescent, subterete, flattish 
above; the rhachis also subterete; more or less prickly, but especially armed 
along the dorsum with some slender, straight, deflexed, 2—3 cm. long spines, 
at first ternate, becoming solitary and smaller above; the cirrus slender, 
regularly armed with small very sharp ternate claws. Leaflets not many, 
8—10 on each side of the rhachis, alternate or  subopposite, papyraceous, 
light green above, powdery-glaucous beneath, rhomboidal, oblong-rhomboidal or 
rhomboidal-cuneate, narrowing from the middle or from a little above to 
an acute, not ansate, base; the upper margins subduplicately lobulate-crenate ; 
the lobules very minutely setose aristate, the apex caudiculate, or prolonged into a 
triangular elongate and at the sides spinülous ciliate point; leaflets radiately plicate 
along several (12—15) very slender primary. nerves, the nerve of the centre being 
slightly stronger than the others; the intermediate leaflets are 18—22 cm. long, 7—9 
em. wide, those of both ends narrower but not shorter. | Male and female spadix 
similar, attached to. the leaf-sheaths by a very slender, recurved, filiform, spinous 
pedicelliform part, frequently 10—15 cm. long, but at times shorter, covered with 
very slender, some long and some short, spines, the longest 8—10 mm. long. The 
spathe is lanceolate-elliptical or broadly fusiform, strongly flattened with very sharp 
edges, 10—25 cm. long, 2—4 cm. broad, equally narrowing to both ends, very 
suddenly contracted above into a narrow linear beak, 1—2 cm. long, thinly. papyraceous 
dry and brittle, of a cinnamon-brown colour, at first powdery, later glabrous; the 
included flattened panicle is cupressiform, has a very slender sinuous axis and is 
divided into several gradually diminishing slender floriferous branchlets ; the bracts 
at each branching are small and trigonous with a subulate point and an amplectent 
base. The spadices bearing only male flowers (not seen by me) according to 
Martius are only slightly ‘less branched (or more? Becc.) than the female-males or © 
polygamous, and their flowers are only slightly larger than the male or neuter ónes 
of the latter. In the female spadices the branchlets bear the flowers in pairs at 
each flexure, every female flower being accompanied by a male (or neuter) flower ; 
they are sutfulted by two short embracing spathels (produced at one side into a 
triangular acute point) and correspond to the involucrophorum and involucre of 
Daemonorops. Female flowers ovoid, or elongate-ovoid, acute or acuminate, 4—5 mm. 
long; the calyx cyathiform, truncate, 3-toothed, strongly striately veined, longer
