C. filipendulus | BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 189 
confluent by their bases), glabrous, rather shining and of about the same colour 
on both surfaces, oblong or elongate-oblong, 25-40 cm. long and 5-10 cm, broad, 
gradually narrowing to the base, rather suddenly narrowed above into a short apex, 
furnished with 5-9 coste which are devoid of bristles or spinules on both 
surfaces; margins naked and remotely spinulous near the apex; tranverse vein- 
lets crowded, more distinct in the lower surface. Male and female -spadices very 
similar, filiform, simply decompound, very slender, 1-l:8 m. long, differing 
from the leaf-sheath flagella only in the few remote partial inflorescences they 
bear; primary spathes very narrow and long and very closely sheathing, truncate 
at the mouth; the lowermost compressed, acutely two-edged, smooth or aculeolate 
on the cuter surface; the upper cylindrical, finely clawed, longitudinally striated, 
not scabrid; partial inflorescences very narrow, divaricate, inserted far above the 
mouth of their own spathes, callous at their upper axilla, with 8-12 very short 
spikelets on each side ; secondary spathes very scabrid or densely covered with 
very short tubercled spicules, tubular-cylindraceous, about 5 mm. long, truncate at 
the mouth and produced at one side into a triangular point which is deflexed 
under the spikelet. Male spikelets very short,. 3-15 mm, long, horizontal, arched 
downwards, with 3-10 very approximate flowers on each side; spathels bracteiform, 
concave, very broad, strongly striately veined as is the involucre, which is shortly 
cupular with irregular margin. Male flowers small oblong, obtuse, 2:5 mm. long; 
the calyx striately veined, broadly 3-toothed; the corolla also striate but polished, 
twice as long as the calyx; stamens with filiform filaments which are inflected 
at the apex; anthers linear; rudimentary ovary slender, columnar, terminated by 3 
small recurved stigmas. Female partial inflorescences as the male ones, but somewhat 
more robust, with the lowest 3-4 spathels empty or without the usual spikelet ; 
spikelets very short, 7-8 mm. long, inserted at the mouth of their own spathe; 
callous in their upper axilla, arched and deflexed, ; with very few approximate 
flowers; spathels bracteiform as in the male spikelets, with very few strong 
nerves converging to the apex; involucrophorum and involucre shallow, sub-cupular, 
strongly striately veined and with irregular margin; areola of the neuter flower 
rather large, ovate and almost two-winged at the sides. Female flowers larger 
than the males, 3°5 mm. long, conical-ovoid, acute; the calyx  sub-urceolate, 
strongly and deeply striately veined and with three broad acute lobes; the 
corolla longer by one-third than the calyx, with lanceolate, acute segments. 
Fruiting perianth not pedicelliform. Fruit small, about 12 mm, long, broadly 
conically ovate, or from a broad base gradually narrowing into an acute and 
slender beak crowned by the recurved stigmas; scales shining, not or indis- 
tinctly channelled along the middle, yellowish, with a narrow often indistinct 
intramarginal dark line and a brown scarious and almost fringed tip. Seed 
irregularly globular, facetted on the back, with concave facets and a shallow broad 
chalazal fovea; albumen equable; embryo basal.
