having the flowers inserted at an angle of about 45° (not horizontal), and in 
its larger fruit. : 
C. arfakianus is characterized by its slender stem, by the cirriferous leaf- 
sheaths, and short non-cirriferous leaves, with a few narrowly lanceolate 
leaflets approximated into a few (three) distant groups; the two terminal 
leaflets free, or but slightly united at their bases; by the very slender and 
long filiform spadices, not very dissimilar in the two sexes, and by the ovoid- 
elliptical, suddenly-beaked fruit, having the seed with equable albumen. 
CALAMUS ARFAKIANUS var. IMBERBIS Becc. 
Vaginis inermibus, in ore minime barbatis; ocrea brevi truncata; segmentis 
interdum obsolete 3-costulatis. 
Differs from the type in having the leaf-sheaths unarmed and strongly 
striate longitudinally, and not bearded at their mouths; in the ocrea being 
short, truncate, and marcescent, and also without bristles; the leaflets in 
this variety have the side nerves more distinct, and at times appear almost 
3-costulate.

Scandent and very slender. Sheathed stem about 1 cm.in diam. Lea/- 
sheaths flagelliferous, not or but slightly gibbous above, rather densely 
covered with scattered or slightly confluent bristle-like spines, becoming 
closer and considerably longer and more hair-like near the mouths of the 
same leaf-shaths and their ocrez, which latter are very short and on account 
of these bristles look densely bearded. Leajf-sheath flagella very slender, 
long, and armed irregularly with very minute scattered claws, Leaves non- 
cirriferous, short (the few seen by me are 35 cm. long); petiole very short, 
or almost obsolete; rhachis fugaciously rusty-furfuraceous, armed with a 
line of solitary, rather long-tipped claws. Leaflets few, about 16 in all ; 
very irregularly set, usually approximate in pairs on each side of the rhachis, 
with irregular vacant spaces of rhachis interposed ; they are narrowly
