C. ferrugineus) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 
489 
densely covered with a removable rusty furfuraceous indumentum and minutely 
scabrid, rather short (45-75 cm. long), rigid, slender, not flagelliform, with few 
partial inflorescences and terminating in a small ( 5-7 cm. long ) aculeolate 
tail-like appendix; peduncular part of the spadix not very long, flattened, 
acutely two-edged, unarmed or nearly so; primary spathes tubular, somewhat enlarged 
above, slightly flattened, keeled on the back, the keel armed with small hooked 
prickles, otherwise unarmed, obliquely truncate, entire and densely ciliate-bearded at 
the mouth, prolonged at one side into a triangular acuminate ` erect point; partial 
inflorescences inserted at the mouth of their own spathe, strongly arched down- 
wards: the lower ones, the largest, about 20 cm. long with 8-10 alternate 
subunilateral spikelets: the upper ones gradually smaller; secondary spathes tubular, 
slightly infundibuliform, more or less angular by mutual pressure, tomentose, ciliate- 
barbate at the mouth and prolonged at one side into a short point; spikelets 
subscorpioid, arched, inserted just at the mouth of their own spathe, assurgent or 
pointing upwards: the lower ones, the largest, 3-4 cm. long: the upper ones 
gradually shorter, with two series of slightly assurgent female flowers (each series of 
ten) and two distinct smaller series of neuter ones; spathels short, bracteiform, 
concave, very broad, acute, strongly deflexed, ciliate, scaly-scurfy; involucrophorum 
explanate, bracteiform, laterally adnate outside its own spathel at the base of the 
one above; involucre explanate, calyculiform, irregularly and acutely 3-toothed ; areola 
of the neuter flower very depressedly lunate. Female flowers with a secund arrange- 
ment (not flatly bifarious) ovoid, acute, about 3 mm. long. Neuter flowers similar to 
the male ones but slightly smaller. rusting perianth shortly but distinctly pedicelli- 
form; the calyx indurated, slightly ventricose and smooth at the base, divided to the 
middle into 3 triangular acute lobes; segments of the corolla ovate, acute, about as 
long and as large as the lobes of the calyx and like this opaque outside and almost 
black when dry. Fruit (wien very young) broadly obovoid, small (5-6 mm. in 
diam. ) slightly tapering towards the base, suddenly narrowed at the summit into a 
rather stout beak; scales in 18 series not or very indistinctly channelled along 
the middle, subshining, reddish-brown towards the point, yellowish at the base, the 
point slightly prolonged, not very adpressed, scarious, erosely toothed. 
Hasrrat.—Borneo. Collected firstly by Jobb, probably in Sarawak ( according to 
a specimen in the Calcutta Herbarium ) and found again by me also in Sarawak 
near Kuching ( Beccari P. B. No. 568 ). 
OBSERVATIONS.—Lobb’s specimen is of an entire leaf and of a female spadix, 
this 45 em. long with 3 partial inflorescences and flowers not yet expanded. My 
specimen is only of an entire female spadix 75 cm. long with 7 gradually 
decreasing partial inflorescences and immature fruit. The conspecifity of this 
second specimen with the first is proved by the very peculiar rusty  scurf 
which after its fall leaves the surface of every organ minutely scabrid; this same 
character has enabled me to discover the shifting of parts of C. ferrugineus and 
Daemonorops cristatus (two species collected by Lobb in Borneo) which had 
oceurred in the  Caleutta Herbarium, and which had led me to attribute to 
C. ferrugineus the leaves of Daemonorops cristatus and vice versd. — C. ferrugineus is a
