86 CXXIV. PIPERACEX. (J. D. Hooker.) [ Piper. 
Wallich’s) 6-7 by 13-23 in., broadest above the middle with narrow unequal bases; 
in some Khacian amans much broader and larger, 8-9 by 54 in. ; in Sikkim and 
Bhotan ones much smaller and more symmetrical, 3-34 by 2-3 in. ; petiole rarely, 
iin. Spikes flexuous; bracts of male pedicelled, the pedicel sometimes elongate; 
anthers 2 sessile 2-celled. Fruit j in. diam.— The long peduncles at once distinguish 
this from P. peepuloides, which i$ 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 m., 
rachis and fruits coalescing into a fleshy cylindric mass 1 in. diam. 
pothoides, Wall. Cat. 6639 BP 
Burma ; at Chappedong, Wallich. 
Habit of the large forms of P. bæhmeriæfolium, but the petioles are longer and 
the fruiting spike very different. Wallich’s specimen is the only one known. 
++ Leaves more or less pubescent. (See also 15. sylvaticum.) 
21. P. anisotis, Hook.f; branches densely shortly tomentose, leaves 
membranous subsessile 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 3 in. 
UPPER 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 13-2 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 din. 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 14-3 in., stigmas very minute, young fruit angular ripe globose. (as.

NEPAL; 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 2-1 in., upper sur- 
face almost shining ; nerves very slender above, strong beneath; nervules indistinct 
on both surfaces. Spikes 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 2 in. diam., not $0 
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, fem. spikes short cylindric. P. Siriboa, Herb. Heyne in Wall. Cat.
