margins very finely and closely spinulous-serrate.

67. €. Reinwardtii Mart.—Scandent, Sheathed stem 1:5-25 cm. in diam. Leaf- 
sheaths beset with unequal, short or long, scattered subulate spines, Leaves, including 
the petiole, 1-1:5 m. long, petiole 10-25 cm. long, armed with long straight or some- 
times hooked spines; rachis armed beneath with solitary, often long-tipped claws and 
long solitary straight deflexed spines, which are light coloured as are those of the leaf- 
sheaths. Leaflets rather numerous, subequidistant, linear-ensiform, distinctly 3-costate, 
the 3 costz spinulous above; beneath only the mid-costa Spinulous. Male spadiz 
elongate-flagelliform ; primary  spathes elongate; partial inflorescences 20-35 cm. 
long; spathels shortly. infundibuliform,, acute, Female spadiz simply decompound ; 
elongate, with not many remote partial inflorescences; spikelets 7-13 cm. long, with 
14-30 horizontally bifarious flowers on each side; spathels (as in the male spikelets) 
strongly veined. Fruiting perianth callous at the base and shortly pedicelliform, not 
or indistinctly striately veined. Fruit subglobular, 10 mm. in diam., suddenly con- 
tracted into a rather long beak. Scales in 15 series, very slightly charnelled along 
the middle and with a rather acute triangular point. |

62. C. heteroideus Bl.—Scandent, slender. Sheathed stem 1-1°5 cm. in diam. 
more or less armed with subulate light coloured spines. Leaves 50-90 cm. long; petiole 
rather elongate; rachis armed beneath with a few long straight deflexed spines and 
with long-tipped claws. Leafiets linear-ensiform, 3-costate ; the 3 coste spinulous above; 
underneath that of the centre sparingly spinulous or glabrous as are the side ones. 
Male spadic slender, elongate-flagelliform, partially supra-decompound, with not many 
very remote partial inflorescences; spathels shortly infundibuliform, prolonged at one 
side into a ciliate, elongate, spreading point. Female spadix simply decompound ; 
spikelets; 3-5 cm. long. Fruiting perianth shortly pedicelliform, coarsely striately 
veined. Fruit ellipsoid, beaked, 12-14 mm. long, 9 mm, in diam. Scales in 18-19
