XEW AXD BAKE SPECIES OF MALAYAN PLANTS. 189 



Perak, Temengoli (Ridley 14575) Female. Selangor, 

 Batu Caves. Burma, Pegu (Kunstler 2220 herb. Kew) Male. 



I believe all these three plants are the same. The species 

 belongs to the section Pseudo-chavica, as Hooker has noted on 

 the specimen. 



Piper Burkillii, Ridl. n. sp. 



Slender climber, internodes jointed, joints slightly en- 

 larged. Leaves membranous, glabrous, lanceolate, slightly un- 

 equal at the base, nerves 1 pair very fine close to the edge, then 

 2 pairs from near the base of the midrib, ascending ; then 1 or 

 5 pairs from the midrib above, all very fine, 3-4 in. long, 1.25- 

 1.35 in. wide, petiole .5 in. long or less. Female spike pe- 

 duncle .15 in. long, spike 1.5-2 in. long, hairy. Bracts very 

 short, rounded. Ovary sunk in a pit. Stigmas short, recurv- 

 ed, subovate 3-1. Fruit unripe, shorter than the stalk .1 in. 

 long. 



Negri Sembilan, Tampin Hill (Burkill 117? >. 



.1. cubebo, allied to P. caninum. The nervation is quite 

 different, the rachis much more slender and not woolly hairy. 



Piper Klossii, Ridl. n. sp. 



Scandent. branches smooth rather soft, nodes not dilate 

 glabrous. Leaves rigidly membranous, nearly ehartaceous, 

 elliptic, gradually blunt, acuminate, base round or nearly very 

 slightly inaequilateral on one side, a little longer than the 

 other, nerves 1 pair from base with T pairs from the midrib 

 horizontal and inarching with the inside pair, glabrous above, 

 sparsely hairy on the back, midrib elevate, thickly pubescent 5 

 in. long and 2.25 in. wide, petiole .25 in. long, grooved. Pe- 

 duncle 1.5 in. long. Female spike in fruit 4= in. long, rather 

 thick, puberulous. Bract cup-shaped. Drupe globose with a 

 short point .2 in. long when dry. stalk much shorter than 

 drupe, thick cvlindric and sunk in rachis. 



Selangor. Gunong Menuang Gasing, Flu Langat (Kloss). 



Certainly a Cubeba, as the fruit is distinctly though 

 shortly stalked. 



Piper cyrtostachys, Ridl. n. sp. 



A glabrous herb : erect, little or not branched about 2 ft. 

 tall, stem herbaceous zigzag, jointed, nodes not swollen, inter- 

 nodes 2 in. long. Leaves membranous, broad, lanceolate acu- 

 minate acute, base very unequally cordate : one lobe about .15 

 in. longer than the other, quite round, edge undulate, penni- 

 nerved. 2 main nerves on one side rising from close to base of 

 midrib, side nerves above, another ascending and several sub- 

 horizontal from both sides 1.5 in. long. 1.75 in. wide, petiole 



R. A. Soc. No! 82. 1920.
