C. pilosissimus.) BECCARIL THE SPECIES OF CALAMUS. -SUPPLEMENT, 37 
which it somewhat resembles. Its position remains somewhat uncertain, but 
probably its true affinities are with the species of group V. 
I consider as referable to C. pilosissimus the upper end of a fruiting spadix 
Collected by M. von Römer (No. 1146) during Dr. Lorentz’s expedition (1909, in 
South Dutch New-Guinea, between 1350-1600 m. above the level of the sea on 
Mt. Hellwig, which is about in the same region whence came the type specimens 
of C. pilosissimus collected by Versteeg. The identification is rendered more probable 
by the fact that in the same locality M. von Kémer has collected a leaf (No. 1194) 
undoubtedly belonging to this species. 
The female spsdiz is evidently flagelliform and very slender, at least in its 
upper part, and terminates in a filiform flagellum armed with solitary scattered 
claws; the spaces between the partial inflorescences are elongate and also armed with 
solitary scattered claws and covered with a thin rusty seurf; primary spathes tubular, 
very narrow, closely sheathing, produced beyond the insertion of their respective 
partial inflorescences into an acuminate marcescent limb. Of the two partial inflores- 
cences present in the specimen seen by me the uppermost is composed of a single 
spikelet, the other is very short and has 4 spikelets, two on each side, and ends in 
a short tail-like appendage; the secondary spathes are infundibuliform and of a firm 
texture jin their lower part aud are produced above far beyond the insertion of 
their respective spikelets into an elongate marcescent limb. Spikelets short, about 
3 em. long, thickish and with only 6-7 closely packed flowers in all; spathels, 
approximate,  infundibuliform, truncate at the mouth, strongly  striately veined ; 
involucrophorum hidden in its spathel; involucre concuve, broadly subcyathiform 
irregularly lobately split, areola of the neuter flower depressedly lunate. The female 
Sowers may be judged from the fruiting perianth about 7 mm. long. Fruiting perianth 
explanate; the calyx split down almost to the base into 3 ovate lobes; the divisions 
of the corolla acuminate, slightly longer but narrower than the lobes of the calyx ; 
spathels, involucres, calyx and corolla strongly striately veined and more or less 
permanently scaly furfuraceous. Fruits crowded into .a group upon the spikelets, very 
regularly ovoid-elliptical, equally rounded at both ends, very suddenly terminating in 
a slender, subterete, about 3 mm. long muero; 22-25 mm. long, inclusive of the 
beak and perianth, and 15 mm. broad; scales very numerous, arranged in 21-22 
longitudinal series; about 12 well conformed, may be counted in each series ; they 
are of a reddish brown colour on the anticous part and pass into greenish yellow 
postieously ; the apex is slightly produced, triangular, bluntish ; they are narrowly but 
rather deeply grooved along the centre, the grooves being continuous from one scale 
to another, so that the entire fruit appears marked with as many longitudinal grooves 
as there are longitudinal series of scales. Seed oblong, slightly broader than thick, 
15-18 mm. long, 11-12 mm. broad, 8:5-9 mm. thick, marked above the middle on 
‘the raphal side by a deep round chalazal fovea, rounded at Loth ends, covered with 
a thin not easily removable (in the dry condition) integument: when cleansed from 
this the surface is even and polished, spadiceous; albumen equable; embryo exactly 
basal. 
The leaf. mentioned above (No. 1194, is apparently from the lower part of the 
plant; it is larger than those figured in supplementay plate 19, and, although 
wanting its basal part bears, on a portion of rachis 45 em. in length, about 50
