nerve on each side of it sparingly bristly above and naked beneath. Female spadi: 
partially supradecompound and apparently large; primary spathes tubular, closely 
sheathing; partial inflorescences panicled, with numerous spikelets, of which the lower 
ones are branched and the uppermost very short.  Pruitmg perianth shortly but 
distinctly pedicelliform. Fruit small, broadly ovate, mucronulate, 10-11 mm. long, 
8 mm. broad. Scales shining, not channelled along the middle.

83. Q. Delessertianus Becc.— Probably scandent and of moderate size. Leaflets 
numerous, rather closely set and equidistant, elongate-ensiform,  sub-5-costulate, the 
intermediate ones 32-35 cm. long, 20-22 mm. broad, the 3 main costz furnished 
with bulbous bristles on the upper surface, underneath the mid-costa only bristly ; 
the margins closely spinulous. Female spadix apparently large and elongate; upper 
primary  spathes elongate, evlindraceous; partial inflorescences (in one specimen) 
30 cm. long, with 13 distichous spikelets on each side; spikelets inserted just at the 
mouth of their respective spathes with a distinct axillary callus, the lower ones about 
6 cm long, with 20 flowers on each side; involucrophorum not pedicellate ; female 
flowers 3 mm. long; neuter flowers more slender, but as long as the female ones, 
their corolla twice as long as the calyx.

84. C. Brandisii Becc.—Scandent. Sheathed stem 10-15 mm. in diam. Leaf-sheaths 
armed with numerous acieular spines, the mouth and the ocrea furnished with numerous 
long bristly spiculz. Leaves about 55 cm. long, the petiole (15 cm. long) armed 
like the rachis with long, solitary, straight, subulate, scattered and in the lower part of 
the rachis deflexed spines. Leaflets few, elongate-lanceolate, very inequidistant, a few 
of them approximate and digitate at the summit, almost all equal, 25-27 cm. long, 
20-95 cm. broad, l- or sub-3-costulate. Female spadiz elongate, flagelliferous and 
^aculeolate at the summit; larger partial inflorescences 15-20 cm. long, with 5-6 
spikelets on each side.

85. C. salicifolius Becc.—Small and bushy. Sheathed stem 6-7 mm. in diam. 
Leaf-sheaths armed with not many short and rather long straight horizontal spines, 
and when not bearing a spadix provided with a very short rudimentary flagellum. 
Leaves small, 20-30 cm. long; petiole very short or 0. Leaflets few, subglaucescent 
elliptic-lanceolate, acute, 5-10 cm. long, 8-15 mm. broad, distinctly grouped into 
5-6 fascicles with rather long vacant spaces interposed, the mid-costa above with 
2-3 relatively long spines, otherwise naked on both surfaces ; margins spinulous, 
Female spadiz short, ultradecompound; female flowers accompanied by a well developed 
apparently fertile male flower. Fruiting perianih shortly  pedicelliform. Fruit very
