210 Materials for a Flora of the Malayan Peninsula. 



inches long, lower spathes unarmed, thinly coriaceous. Internodes 

 armed with short hooks. Spathels smooth infundibular tubular with 

 a short distinct lanceolate limb and mouth ciliated. Spikes distant 

 secimd, la-3 inches long. Flowers distant, spathellules ribbed, rather 

 long, limb ovate acute. Bract cup-shaped. Calyx strongly ribbed. 



Singapore: (Lobb); Johor : Batu Pahat (Ridley 11215). This is 

 very near C. Oxleyanus but the leaflets are equidistant. Endemic. 



37. C. LAXISSIMUS, n. sp. Leaf rachis slender obscurely angled 

 armed with stout solitary or paired hooks, leaflets ensiform with a long 

 point, opposite, in distant pairs over a foot long t inch wide, nerves 3 

 to 5, bristles a few on the edge and many on the point. Male spadix 

 slender branched over 3 feet long, peduncle one foot long i inch 

 across, flattened with needlelike thorns on the edge i inch long. Spa- 

 thes long tubular thin lowest 9 inches long with a lanceolate thin limb, 

 the mouth armed with erect slender processes an inch long, upper spathes 

 similar but smaller. Branches slender 3-4 inches long. Spathels 

 very short, funnel-shaped. Spikes very short, two-flowered, flowers i 

 inch long. Calyx tubular base rounded, lobes ovate. Corolla but little 

 longer obtuse, shining smooth. Female spadix 6 feet or more long, 

 rather stouter, branches 6 inches stouter, spikes one to 8 or more, flower- 

 ed. Calyx base dilate, rounded, tube cylindric, narrower, ribbed, lobes 

 short. Corolla hardly longer. Stigmas rather long. Spathels scurfy. 



Pahang : Tahan River (Ridley). A very curious plant, the very 

 elongate branched spadix being nearly or quite unarmed. In one female 

 spadix there are a few hooks below the spathes. The spathes have a 

 lanceolate papery limb like those in Ciramosissimns but smaller, and 

 some remarkable stiff flat processes, 6 inches long in the female along 

 the edge of the mouth. The bi'anches being covered closely with spa- 

 thels and flowers might be taken for spikes but they bear very small 

 two-flowered spikes, rarely more, and sometimes solitary flowers. 

 Endemic. 



38. C. AQUATILIS, Ridl. Journ. Roy. As. Soc. S. Br. Vol. 41, p. 43. 

 Stem fairly stout, about 30 feet long covered densely with black bristle- 

 like spines. Leaf long flagelliferous, sheath armed with copious black 

 spines in short rows, petiole a foot long, stout back rounded, edge armed 

 with spines of different sizes flattened and 2 inches long or less, spines 

 at the base hlack, long and slender ; rachis smooth on the back spiny 

 on the edge; leaflets numerous equidistant linear acuminate, 1 foot long 

 over an inch wide, bristles short along the edge and back scattered ; 

 flagellum 5 feet long, hooks in half whorls numerous. Panicles very 

 large and stout, lower sheaths tubular an inch through with numerous 

 short decurved spines singly or in twos and threes, black tipped, 

 chiefly on the back and sides in the upper part. Branches about two 

 feet, secondary spathes tubular unarmed an inch long. Male branch- 

 lets numerous, G inches long, spathels tubular short i inch, spikes
