86 cxxiv, PIPERACE.E. (J. D. Hooker.) 



(Wallich's) 6-7 by l$-2 in., broadest above tbe middle with narrow unequal bases; 

 in some Khasian specimens much broader and larger, 8-9 by 5^ in. ; in Sikkim and 

 Bhotau ones much smaller and more symmetrical, 3-3 by 2-3 in. ; petiole rarely 

 ^ in. Spikes flexuous ; bracts of male pedicelled, the pedicel sometimes elongate; 

 anthers 2 sessile 2-celled. Fruit in. diam. The long peduncles at once distinguish 

 this from P. peepuloides, which is included with it under Wallich's No. 6654. 



20. P. pothiforme, Wall, ex Cas. DC. in Prodr. xvi. 1.351 ; tall, quite 

 glabrous, leaves membranous petioled 7-9 by 3 in. linear-oblong acuminate 

 base oblique cordate, nerves 5 of which 3 run to the tip, fruiting spike 3 in., 

 rachis and fruits coalescing into a fleshy cylindric mass 1 in. diam. P. 

 pothoides, Wall. Cat. 6639 B P 



BURMA ; at Chappedong, Wallich. 



Habit of the large forms of P. boehmeritBfolium ) 'bui the petioles are longer and 

 the fruiting spike very different. Wallich's specimen is the only one known. 



ft Leaves more or less pubescent. (See also 15. sylvaticum.') 



21. P. anisotis, HooJc.f. ;. branches densely shortly tomentose, leaves 

 membranous subsess-ile obliquely oblong acuminate from a very unequal 

 auricled base 5-7 nerved from the very base, sparsely hairy above beneath 

 rusty tomentose on the veins especially, fruiting spikes in. 



UPPEB ASSAM ; Thaumathaya, in the Mishmi Hills, Griffith. 



Habit of the branches of P. longum, but the leaves are more unequal-sided and 

 more cordate. Leaves 3-5 by l|-2 in.., very thin, finely acuminate, nerves slender, 

 nervules transverse. Fruiting spikes cylindric, like those of P. peepuloides ; peduncle 

 hispidly hairy, slender; bracts minute, peltate. Fruit about ^ in. diam. 



22. P., aurantiacum, Wall. Cat. 6658 A; stems climbing and root- 

 ing glabrous, leaves all petioled coriaceous ovate elliptic- or orbicular- ovate 

 caudate-acuminate 5-nerved hairy or glabrate beneath base rounded or acute, 

 spikes li-3 in., stigmas very minute, young fruit angular ripe globose. Cas.

NEPAL j at Sheopore, Wallich. ASSAM, from Suddya and elsewhere, Griffith. 



A rather stout climber, of a yellowish colour when dry ; branches not hard or 

 woody, glabrous. Leaves or young trailing shoots with petioles 2-3 in. long ; 

 leaves on the main stem and branches 3-4 in. long, with petioles f-1 in., upper sur- 

 face almost shining ; nerves very slender above, strong beneath ; nervules indistinct 

 tm both surfaces. Splices drooping, peduncle of both sexes about as long as the 

 petioles ; flowers densely crowded ; bracts peltate, quite glabrous ; stamens 2, anthers 

 reniform, cells confluent dehiscing across the tip ; fruiting spikes variable in length. 

 Fruit distinctly pyramidal when young and dry, when ripe about in. diam., not so 

 crowded as usual in the section from many not ripening. It is curious that this very 

 distinct species has not been collected in Sikkim or Bhotan. 



23. P. Hapnium, Ham. in Wall. Cat. 6650 D ; climbing, branches 

 stout rooting warted below, leaves petioled rugose oblong or oblong-lan- 

 ceolate acuminate 7-nerved above the base nerves beneath pubescent or 

 glabrate, base very unequal auricled on one side, peduncles longer than the 

 leaves, fern, spikes short cylindric. P. Siriboa, Serb. Heyne in Wall. Cat.
