€. megaphyllus.] ^ BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT, 67 
more or less confluent but not verticilate, very sharp, dark brown claws. Leaflets 
very few and very large, 14 on the whole (in one leaf), irregularly approximate 
into 3-4 groups, with long vacant spaces interposed between the groups, and 
3-6 cm. apart between themselves on each side; they are concavo-convex, papyraceous, 
thin and tough, not rigid, almost glossy, similarly green and quite destitute of hairs 
or spinules on both surfaces, oblong-spathulate and gradually tapering from above the 
middle to a rather acute base, while above narrowing rather suddenly to a broadly 
triangular, acute, not bristly tip; they have 4-5 almost equal, slender, sharp, smooth 
main costae, and several very slender secondary nerves; transverse veinlets extremely 
numerous and approximate (2-3 in a millimetre), pellucid, very continuous, very slender, 
but very sharp on both surfaces; the intermediate aud largest leaflets are 35-45 cm. 
long and 8-10 em. broad: the upper ones somewhat shorter: the lowest very small 
Male spadiz......Female spadic rather elongate (1°20 m. long, Elmer) recurved or pendu- 
lous, rather slender, simply branched or with few distant small undivided partial 
inflorescences, probably subflagelliform at .its upper end (this part not seen by me); 
primary spathes tubular, slightly enlarged and rather loosely sheathing above, about 
20 cm. long, obliquely-truncate at the mouth, and produced at one side into a 
broadly-triangular acute point: they have a dull finely-striate surface, and are very 
sparingly prickly in their upper part, especially on their superficial, dorsal keel; 
the lowest spathe has a partial inflorescence like the upper ones, and is very similar 
to these, but it is rather acutely bicarinate; partial inflorescences inserted just at the 
mouth of their respective spathes: they are arched, above 12 cm. long, and carry 
5-7 gradually diminishing spikelets on each side; secondary spathes with a terete, 
solid, axial part, and suddenly expanded into a loose, infundibuliform, truncate, 
ciliolate limb, slightly apiculate at one side; spikelets inserted far above the mouths 
of their respective spathes, arched-subscorpioid; the lower spikelets are 2-5-3 cm. 
long, and have 12-14 flowers on the whole, arranged in two assurgent series; the 
uppermost spikelets have 4-5 flowers only; spathels briefly infundibuliform ; involu- 
crophorum disciform, borne on a short neck or subpedicel inserted laterally at the base 
of the spathel above its own; involucre with a conspicuous, orbicular, flet scar, edged 
by a narrow circular limb; areola of the neuter flower punctiform, inconspicuous. 
Fruiting perianth briefly but distinctly pedicelliform, about 2 mm. long and broad. 
Fruit exactly spherical, 13 mm. in diameter, with a very small beak abruptly rising 
on the convex top; scales in, 15 longitudinal series, very thin, glossy, slightly convex, 
very faintly grooved along the centre, straw-coloured passing into reddish-brown at 
the edges, their points slightly produced, narrowly scarious and erosely toothed. 
Sed enveloped by a copious, fleshy, sour integument, orbicular, 7 mm. in diameter, 
even surfaced, flattened, plano-convex or sublentieular, flat on the raphal side with 
a central pitlike chalazal fovea. Albumen equable. Embryo basal. 
Hasitat.—The Philippines: Island of Mindanao, district of Davao, on Mount Apo 
at 1,000 m. on the Talon side of the mountain range in open light-wooded ridges,

SurPL. Prate 35.—Calamus megaphyllus Becc. Portion of the sheathed stem ; 
intermediate portion of a leaf, and another portion with its terminal cirrus; portion of 
the fruiting spadix. From Elmer’s No. 11878 in Herb, Beccari.
