formed of 2 opposite leaflets onlv ; the leaflets are lanceolato-ensiform, or 

 oblanceolate, and taper almost equally to both ends, have the base rather 

 acute, and are shortly and suddenly acuminate in a slightly bristly-spinulous 

 tip ; are papyraceous, rather firm, glossy on both surfaces, but especially 

 above, very slightly paler beneath, with an acute mid-costa and a few slender 

 side-nerves, all quite naked on both surfaces, though at times the mid-costa 

 is slightly spinulous above near the apex ; margins remotely and minutely 

 ciliate-spinulous, more closely near the apex ; transverse veinlets very 

 crowded, fine and sharp ; intermediate leaflets 40-50 cm. long, 3'5-4 cm. 

 broad, the lowest smallest, those of the terminal group shorter, but not 

 narrower. Male spadix somewhat shorter than the leaves (70 cm. long in 

 one specimen), erect, strict, having an elongate pedicellar part bearing only 

 one dense and narrow cupressiform panicle, about 20 cm. long (perhaps at 

 times the spadix is longer, and with more than one panicle) ; the primary 

 spathe is very elongate, and at first enfolds the spadix ; it is tubular, 

 flattened with acute edges, closely sheathed in its lower part, and is produced 

 above into an open, thinly membranous, lacerate, lanceolate-acuminate limb, 

 it is sprinkled all over outside with minute tuberculiform prickles ; the 

 panicle is composed of several gradually diminishing, very approximate, very 

 densely flowered, short spikelet-bearing branchlets, inserted at an angle of 

 45, subtended by secondary thinly membranous, dry, lanceolate-acuminate, 

 more or less lacerated, secondary spathes, only a little shorter than their 

 respective branchlets ; the branchlets have the appearance of being small, 

 simple, cylindrical spikes, 5-6 cm. long in the basal part of the panicle, 

 gradually a little shorter above ; in fact, however, they are composed of 

 several, very short, very closely drawn together, alternate, distichous 

 spikelets, the lowest of which are 8-10 mm. long, with 7-8 very approximate 

 flowers on each side ; the upper spikelets gradually diminish in length and 

 number of flowers ; spathels bracteiform, membranous, concave with a 

 triangular acute apex, surpassing the involucre; this is deeply cupular, 

 or subcampanulate, truncate, not distinctly two-keeled, and bidentate on the 

 side next to the axis. Male flowers very closely packed together, oblong, 

 6 mm. long; the calyx deeply 3-lobed; the corolla twice as long as the 

 calyx, narrowing a little above to a bluntish apex. Female spadix and fruit 

 unknown. 



Hab. Humboldt Bay, ridge behind the village, 700', scrambling in high 

 forest. (?. Jan. 6267. 



A very distinct species, but with very marked affinities with C. macro- 

 chamis Becc. It belongs to Group V. of my monograph, characterized 

 mainly by non-cirriferous leaves, and by the leaf-sheaths furnished with 

 a long clawed flagellum ; in that group it falls into the division which 

 contains C.macrocldamys and other Papuan species, all having very large and 

 elongate chartaceous ocrese. Even among these species C. humboldtiantti
