MB. N. E. BROWN ON SOME NEW ABOIDE.E. 243 



A glabrous aquatic. Petioles 2-6 in. long, vaginate at the base, 

 1-1 1 line thick. Lamina elliptic, broadly elliptic, or ovate, sub- 

 acute or obtuse, base cordate, with rounded lobes and a short 

 narrow sinus ; margin erose-dentate (the teeth are formed by the 

 margin being revolute for short semilunar spaces); primary lateral 

 veins four on each side of the midrib, the two lowest pairs arising 

 at the base and excurrent at the margin, the third pair arising a 

 little above the base, and together with the fourth pair, which 

 arises from |-1 in. above the base of the midrib, uniting again 

 with the midrib near the apex, all strongly curved ; secondary 

 veins transverse between the primary, between them the leaf is 

 strongly depressed-bullate, dark green above, paler beneath. 

 Spathe subsessile, longer than the petioles ; tube cylindric, 2-2| 

 in. long, pallid ; limb blackish purple, in the unopened spathe 

 slightly inflated, and prolonged into a subulate erect tail4-4| in. 

 long. Spadix \ lin. long; syncarpidium sessile, G-7-celled; styles 

 linear-subulate, stigmatic down the underside, somewhat spread- 

 ing. Fruit ovoid, | in. long, the cells with four seeds in each ; 

 seeds elongate, falcate, pale browu. Plumule of embryo of four 

 or five subulate leaves, arising from the dorsal side a little below 

 the middle. 



Discovered by Mr. Burbidge in pools, in shady jungles near 

 the Lawas River, North-west Borneo. Mr. Burbidge informs me 

 he found some plants entirely floating, others growing in shallow 

 water with ouly their leaves floating ; it flowers during the dry 

 season, when the water is very shallow. In the specimens seen 

 by me all the spathes were closed, as represented in my drawing, 

 but probably the base of the limb opens a little. 



This species seems to be closely allied to O. longicauda, Becc., 

 which I have not seen; but, according to Prof. Engler's de- 

 scription of it, my plant differs in its strongly depressed-bullate 

 leaves with erose-dentate margins and an extra pair of primary 

 lateral veins. It is also allied to C. bullosa, Becc, from which it 

 differs in its much longer pointed spathe, and to C. Oriffithii, Sch., 

 from which it is easily distinguished by its much longer pointed 

 spathe and bullate leaves.

 data, made by Mr. J. Mottley in Borneo, and now preserved in 

 the Kew Herbarium, which adds to our knowledge of the plant :—
