the plant probably cHmba by the aid of tlvi long-clawed flagellum wliich terminates
the spadis. C. Moii possibly may not difEer from C. radicalis which, however, is
8o imperfectly known that an exact comparison of the two is actually impossible.
In the leaves of C. Moii I have not found any spiny bristles in the upper face of
thfe rachis nor apinules on the costfe of the under surface of the leaflets, but
otherwise the leaflets of the two plants are very much like each other.
The characteristic ma*ks of C. Moti arc the leaf-sheatlis densely armed with
subseriate spreading spines; the large leaves with terete petiole and numerous large
eusiform leaflets which are bristly on 3 cost® above; and tho epadix with a-very
long and strong terminal clawed flagellum.

DESCRIPTION.—Scandent (Wendland & Drude). Stem Leaf-sheath
fagelliferoua and densely aculeate (Wendland & Drude). Leawi not cirriferons, with
numerous equidistant leaflets (Wendland & Drude); in the small portion seen by
me probably from the middle the racliis is fugaciously fui-furaceous, flattish below,
where armed along the middle with small solitary claws, bifaced above, where
fui-nished on the acute angle with some very slender bristly spinules; leaflets
alternate, 3 cm. apart, elongate-lanceolate or ensifotm, rather suddenly plicate at the
base, gradually long-acuminate into a subulate bristly-spinulous apex, 45 cm. loog
and 20-23 mm. broad, green even when dry, rather shining on both surfaces,
hardly paler beneath thinly papyraceous, subtricostulate mainly near the base in the
upper surface, where the mid-costa is acute and raised, and the side costa) are
very slender, evanescent and undistinguishable from some other secondary nerves
towards the apex; the 3 costulfe are furnished above with a few long dark
bristles; on the undersurface the mid-costa is not prominent, and on this as well
as on 1-2 slender nerves on each side of it are some very small appressed
spinules easily overlooked; margins wiih many veiy short approximate appressed
spinules; lower margins slightly thickened by a slender nerve; transverse veinlets
rather sharp, rather distant, much interrupted.—Other parts unknown.
HABITAT.—N, E. Queensland: to tho north of Port Mackey, discovered by
Nernst.
OBSERVATIONS,—This Calamus has been described by its authors as stolon iferoua,
t i g h scandent, with non-cirriferous leaves, which bear numerous equidistant leaflets
and with flagelliferous densely aculeate Icaf-sheaths; but tho description is based on
the specimen of only one leaf, a fragment of which I received from tho late'
Baron Ferd. von Mueller. With such imperiect material it is very di£6cult to point

.out the affinitiea of thia species, tbougii very probably it will range near C
amtralis. Certainly it cannot be referred to C. MmlUrii, as was supposed by
Bentham, nor to any other known Australian Calamus, except to the recemly
described C. Moii Bailey. A leaf of a Cnhtmtt gathered by Miss E. Bauer on the
Bloomfield River Queensland, and also communicated to me by von Mueller
probably belongs to C. radicalis.

DESCBIJTIOK,—High scandent. Sluatlui stem about 2 cm. in diam. Uaf-shiathB
flagelliferous, slightly gibbous above, ornamented with very many crowded horizontally
or obliquely seriate sinuous subannular or interrupted narrowly lamelliform ridges,
which are further finely toothcd-spinulous on their crest. Uaf-shmih Jlasdla very
long, compressed in the basal portion, where serrulate or furnished with approximate
very small spinules on the edges, and cylindraccous upwards where irregularly armed
with half-whorlod or scattered claws. Ocrea deciduous. Leaves rather large, 1.7 m
long, not oitriierousj petiole rather elongate (18 cm. long), flat above where densely
armed all over the surface as well as on the margins with short straight spines,
rounded and smooth beneath; rachis broadly channelled on each side in its lower portion
above (where are inserted the leaflets), and bifaced with acute and smooth angle in
its upper part; beneath the rachis is regularly and closely armed at the sides end
along the middle with short stout claws, which are solitary in the lower and in
termediate portion and are ternate near the summit; leailets very numerous, equidistant,
patent, very closely and very regularly set, almost always opposite, very naiTow
linear, very long-acuminate, green and concolourous on both surfaces, papyraceous,
subtricostulate, the mid-costa acute and tho side costaj slender but distinct above
faint beneath, the 3 rather closely and minutely bristly on both surfaces; the largest
leaflets 25-30 cm. long, 1 cm. broad, the uppermost gradually shorter, tho two of
the terminal pair small and narrow, free at the base; transverse veinlets not very
conspicuous and much interrupted; margins very finely eiliolate.—Other parts unknown.
HABITAT.—N. E. New Guinea ; at Eamoi, Beeeari P. P. No. 416.
OBSEEVATIOSS.—This species does not appear allied to any other, but is perhaps
to 0. serrulalus; though seen only in a sterile condition, it is very well marked by
the peculiar ornamentation of the leaf-sheaths, and the numerous very narrow equidistan.
