Piper.] CXXIV. PIPERACER. (J. D. Hooker.) 93 
in Delessert’s Herbarium is this ; unfortunately Roxburgh’s names of Polygonums and 
Peppers are often at issue both with his descriptions, and these again with his Icones ; 
he quotes Linnæus for his Malamiris, but Linnæus includes plants of both the old and 
new worlds under Malamiris. Rheede’s figure of Linnsus' plant of that name, 
Amalago (vii. t. 16), cited by Roxburgh, cannot well be P. attenuatum.

A branching climbing shrub, with apparently soft branches, much compressed and 
furrowed when dry in the Ceylon specimens. Leaves 4—5 by 2-3 in., more coriaceous 
than in P, attenuatum, with much shorter petioles, and never rounded-ovate as in 
that plant, base acute or rounded rarely cordate, nerves not so basal; petiole j-$ in. 
Male spikes 5-6 in., flowers rather distant ; stamens 2-4; female lengthening much 
In fruit, rachis slender, glabrous. Fruit 4 to nearly 4 in.—I accept this as Lamarck 8 
: Sylvestre with great doubt, and I find it difficult to define it by description from 
narrow-leaved forms of P. attenuatum, and from some states of P. argyrophyllum, 
but feel sure it is quite distinct from the former. A specimen in Wight’s Herbarium 
18 marked P. trioicum, as is another from Roxburgh's Herbarium, but the fruit seems 
too small for that form of nigrum, the rachis too is slender, and leaves too membra- 
nous. I refrain from citing any of the extra-Indian descriptions or habitats for 
sylvestre, but there is in Herb. Hook. a plant said to be from Mauritius which tallies 
with this, and is marked P. sylvestre by Miquel ; it is probably a garden specimen, 
and is in male fl. only.

shortly petioled very membranous ovate elliptic-ovate or -oblong or ovate- 
cordate acuminate base'acute or rounded 2-3-nerved towards the base, 
“erves slender alternate, spikes very long and slender, fruiting rachis very 
Canter glabrous or pubescent in the scars, bracts confluent with the rachis.

A slender climber, with branches that do not appear to shrink in drying. Leaves 
.In. very variable in breadth, always thinly membranous, base usually equal ; 
Petiole 3-4 in. Male spike very slender; bracts with free rounded tips, pe lancle

an wht, not having seen male plants, is disposed to regard this as the female of ; 
amd rophyllum, and though males are now known, they da not help to distinguish 
nr, The pubescence, which is the best character for this, is far from constant in 
mount, and is sometimes almost evanescent. So too the development of the bracts 
close fruiting rachis is very various. A Javan plant of Zollinger’s (IL. No. 304) 
Closely resembles this,
