92 CXXIV. PIPERACER. (J. D. Hooker.) (Piper. 
nodes much enlarged, leaves petioled thinly coriaceous broadly elliptic or 
rounded abruptly acuminate, 5-nerved from near the rounded rarely sub- 
cordate base, peduncles slender longer.than the petioles, female spikes very 
slender longer than the leaves, flowers very minute in separate whorls.

Apparently shrubby. Leaves very symmetrical for the genus, dull brown when 
dry, 3-4 by 2-3 in., nerves slender, nervules distinct on both surfaces ; petiole slender, 
jin. Female spikes alone seen; flowers sometimes in a broken spiral, but usually 
in distinct whorls; bracts cupular, confluent below with the slender quite glabrous 
rachis. Fruit 3 in. long, ellipsoid, with a very short style when dry.—A very distinct 
species, which Miquel appears to have overlooked in Wallich’s Herbarium, where 
. the only specimen is fastened on a sheet with two other species (P. caninum and 
Lonchites). In the Hookerian Herbarium he has named it “a P. acre, Bl, vix 
diversum ;"— it differs from P. acre totally in the bracts and flowers. i 
** Bracts of the female spike adnate to the rachis with decurrent raised 
more or less membranous margins which are confluent with the bracteoles on 
either side of the ovary. (The species of this group are involved, and I have 
failed in the attempt to dissociate Nos. 40 to 43.) 
38. P. rhytidocarpum, Hook. f.; a stout quite glabrous climber, 
leaves long-petioled large coriaceous elliptic ovate oblong or orbicular 
acuminate not glaucous beneath 3—5-nerved above the rounded acute or cor- 
date base, spikes very long, fruiting females 8-12 in., bracts with slightly 
raised margins, fruit granulate (when dry). P. aurantiacum, Wall Cat.

. Habit and foliage of P. nigrum, but distinguished by the long petioles, often 
2 in. long, larger leaves, attaining 7 in. in breadth, very long spikes, raised margins 
of the bracts and granulate fruit.—Miquel has named a specimen without fruit 2 
Herb. Hook. as P. trioicum? and alludes to it in Syst. Pip. (314, parag. 3).

branches soft compressed angled and grooved when dry, leaves long- 
petioled membranous orbicular-ovate or cordate abruptly acuminate uppet 
more ovate glabrous or puberulous beneath 7-nerved from near the bases 
fruiting female spikes very long slender, bracts decurrent with raised mem-

Apparently a rambling species, not unlike P. sylvaticum. Branches stout, buf 
evidently soft, flexuous, glabrous. Leaves 24-6 in., often as broad as long, from finely 
downy to glabrous beneath ; base usually equal rounded truncate or cordate, of tbe 
upper usually acute; nerves slender; petiole 1-3 in., rarely shorter. Male spikes 
slender; bracts adnate, cupular; bracteoles slender; stamens 2-4. Female spikes 
very slender, lengthening in fruit to 9 in.; rachis glabrous, except in the ciliate scar? 
left by the fruit; ovaries ovoid ; stigmas minute. Fruit globose à in. diam.—The 
7 basal nerves seem to distinguish this from the following. Cas. DC. refers the Sirium 
.of Rumph (V. 119, t. 2) and Vahl's P. diffusum to it, but the evidence is very slight.
