27. CERATOLOBUS, Blume. 



Palms with the habit and foliage of Korthalsia, but with flagelliferous 

 leaves. Spadix very slender, loosely panicled; branches filiform ; peduncle 

 very long, pendulous, prickly, usually adnate to the sheath of the leaf 

 opposite ; spathe small, solitary, membranous, narrow, flattened, beaked, 

 at length split down the ventral face ; flowers polygamous, in pairs, the 

 upper ebracteate, the lower bracteate and bracteolate. Male fl. Calyx 

 small, 3-fid; lobes triangular, valvate ; stamens 6, on the bases of the 

 petals, anthers linear ; pistillode minute. Fern. fl. Calyx of the male; 

 corolla 3-fid, valvate ; ovary- ovoid ; ovules 3, basilar, erect. Fruit small, 

 1-celled, 1-seeded, pericarp as in Korthalsia. Seed globose, erect ; testa 

 fleshy ; albumen ruminate ; embryo basilar. Species Malayan. 



1. C. Isevigratus, Becc. mss.; leaflets in inequidistant groups of 2-3 

 pairs narrowly linear- or ob- lanceolate acuminate suddenly contracted into 

 a long straight point naked on both surfaces and margins, spadix shortly 

 peduncled, fruit spherical broadly beaked. Calamus laevigatus, Mart. Hist.

PEKAK, King's Collector (575, 971, 5916) ; on Waterfall hill, Wray (2919). 



Stem 15-20 ft., about in. diam. Leaves 18-30 ft. ; leaflets concolorous, dark 

 green, 5-9 by - in., thin ; rachis slender, sparsely armed with solitary recurved 

 spines ; petiole very short, base tumid ; sheath strongly ribbed, armed with scattered 

 simple flattened spines. Spadix 4-8 in., very shortly peduncled, erect, narrow ; 

 branches slender, sparsely pubescent. Spathe 6-10 in., linear-lanceolate, coriaceous, 

 smooth. Male fl. sessile, subglobose, % in. diam. ; calyx cupular, 3-lobed and broad 

 petals and bracteoles deeply grooved. Fruit brown, sabglobose or ovoid, narrowed 

 to a broad conical beak; scales obscurely channelled.. Seed obtusely tubercled. 

 Fruiting calyx as in the male, but petals much narrower and longer. 



Var. angustifolia, Becc. mss.; more slender, leaflets narrower gradually produced 

 into a slender point, median costa setulose, spathe 4 in. long, much thinner and spadix 

 much smaller, probably a different species. Perak ; King's Collector (1879). 



2. C. K.ingrianus, Becc. mss. ; leaflets few large cuneately rhomboid 

 or trapezoid, lobed and toothed in the upper half deeply plicate pale be- 

 neath, spadix sessile, fruit spherical shortly broadly beaked. 



PEBAK, Hullett (Herb. Calc. 2547, 2856, 5589) ; Wray (2869). 



Stem 20-25 ft., about 1 in. diam. Leaves 3-4 ft. ; leaflets 6-9 by 3-4 in., 

 lower half trian^ular-cuneate ; rachis stout urmed with short solitary and 2-5-fid. 

 claws ; petiole 6-8 in., more or less muricate and armed with scattered short simple 

 and compound spines; sheath transversely muricately ridged, unarmed, young

 channelled. Seed nearly smooth. Fruiting calyx minute ; petals broadly ovate.

Scandent monocarpic spinous palms, stem very long. Leaves flagelli- 

 ferous ; leaflets linear lanceolate. Spadix simply branched ; branches 

 very long, pendulous, clothed with closely imbricating distichous inflated 

 coriaceous persistent spathels which conceal the spicate dioecious flowers.
