I collected a specimen of this on the Hermitage Hill 

 in Perak, and have never seen it since, and unfortunately 

 omitted to record the size of the plant. It is evidently 

 allied to L. pei'icycla, Zipp., Pericycla pendulifiora of 

 Blume, a native of New Guinea, from which it differs in 

 having solitary sessile, not stalked flowers in pairs. 

 The panicled inflorescence is unique in Malay Licualas as 

 at present known, and is the characteristic of the section 

 Pericyclus of which the New Guinea species is the only 

 other one known. It is to be hoped that any one visiting 

 the Hermitage Hill will recollect this curious plant and 

 bring full details of its habit and size. 

 Calamus aquatilis, n. sp. Stem fairly stout about 30 feet long 

 covered with dense bristle- like black spines. Leaf large 

 flagelliferous armed with copious black spines in short 

 rows, petiole a foot long stout black rounded, edge armed 

 with spines of different sizes flattened 2 inches long or 

 less, those at the base black long or slender, leaflets 

 numerous equidistant linear acuminate 1 foot long an 

 inch broad, bristles short scattered along the edges and 

 back, flagellum 4 feet long, hooks in half whorls 

 numerous. Panicle very large and stout, lower sheaths 

 tubular an inch through with numerous decurved spines 

 single or in twos and threes black tipped, chiefly on the 

 back and sides on the upper part. Branches about 2 feet 

 long, secondary spathes tubular unarmed an inch long, 

 male branchlets numerous 6 inches long, spathels tubular 

 about J inch long, spikes subdistichous recurved § inch 

 long green. Spathellules saucer-shaped with a small 

 ovate limb, sepals oblong lanceolate. Petals as long 

 oblong lanceolate thicker. Stamens, filaments rather 

 long slender, anthers long narrow. Female branchlets
