C. paspalanthus. | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 997 
with the peduncle in its lowest portion; partial inflorescences kept spreading or almost 
horizontal by a very large axillary callus (this with a distinct transverse rima) and 
inserted very far inside their respective spathes, but apparently free from these, which 
are in their upper part almost destroyed and reduced to filamentous strips, very lax, 
all of about the same size, 20-25 cm. long with 5-6 spikelets on each side, their axis 
straight, slender, but rather rigid; secondary spathes narrowly tubular-infundibuliform, 
membranous, closely sheathing, prolonged at the summit into a long lacerate scarious 
decayed point, often armed about to their middle on the back with very small claws; 
spikelets considerably thicker than the axis of the inflorescence, straight or sinuous, 
horizontal or slightly deflexed, inserted inside the mouth of their respective spathes 
with a distinct axillary callus, 10-12 cm. long (the upper ones slightly shorter), with 
15-20 flowers on each side; spathels infundibuliform, finely striately veined, narrow 
and gibbous at the base, with thin subscarious often decayed margin; sivettictoptiorons 
irregularly cupular, half immersed in its own spathel and attached at the base of the 
one above which is there slightly hollowed to receive it; involucre exactly cupular, 
rather deep, truncate; areola of the neuter flower very distinct, broadly ovate or 
suborbicular, callous, very sharply bordered and slightly projecting from the involucrés, 
Fruiting perianth explanate, split into 6 almost equal parts. Fruit very broadly ovate, 
mucronulate, about 18 mm. long; scales in 18 series, opaque or only partially 
subsbining, dark reddish-brown, slightly darker near the margins, convex and not 
channelled along the middle, slightly prolonged into a not fimbriate rather obtuse 
point, Seed very anomalous, flattened, suborbicular in outline, about 1 cm. in diam., 
with a sharp border, emarginate at the base where slightly thickened and with 2) 
or 8 more or less distinct conic teeth; the surface smooth but not polished, flat and 
with a round superficial central chalazal fovea on the raphal side, slightly convex 
on the back; albumen equable, bony; embryo basal.

to a specimen preserved in Herb. Kew, 
OnsERVATIONS.—After very careful examination I have found some slight differences 
between the Bornean type-specimens of C. paspalanthus, and those of the Malayan 
Peninsula, which have induced me to consider (these last as belonging to a local or 
geographical variety (see observations on the variety). 
The male flowers in Lobb's male specimen are not fully developed ; they are ovate, 
with the calyx superficially urceolate and broadly three-toothed and distinctly striately 
veined, as also very conspicuously are the spathels and the sides of the involueres, 
whilst in the fully developed spikelets of the Malayan specimens the flowers are 
cylindraceous and the spathels not or very indistinctly striate. C, paspalanthus is a 
very remarkable and easily recognizable species by its leaf-sheaths conspicuously swollen 
in their upper part at the base of the petiole; the numerous equidistant approximate 
narrowly linear leaflets with 3 acute costae, which are sparsely bristly above and 
very minutely and closely ciliate beneath; the very elongate spadices with the spathes 
as long as or longer than their respective inflorescences, tubular at the base and 
reduced into long strips in their upper part; the male spadix with numerous small
