F. v. 21. Frag in . vi. 180; Benth. FI. Austr. vi. 209. A tall but apparently 
herbaceous glabrous twiner. Leaves in the typical form usually ovate-oblong 
or almost obovate, obtuse, truncate or cordate at the base, and 2 to 3in. long ; 
in the Australian variety broader, acutely acuminate, more deeply cordate, 3 
to 6in. long, membranous, 5- or 7-nerved. Flowers in short axillary racemes, 
sometimes almost contracted into clusters, the pedicels usually longer than 
the common rhachis, and each with a small bract at the base. Perianth not 
seen in the Australian variety, in the typical form with a nearly globular 
utricle of nearly 2 lines diameter, the tube slender and about 3 lines long 
above the utricle, the lip oblong-linear or narrow-lanceolate, obtuse, f to nearly 
lin. long, slightly dilated and almost 2-auriculate at the base. Capsule ovoid, 
1 to liin. long. Seeds flat, obtusely triangular, slightly tuberculate in the 
centre, with a broad smooth margin. — R. Br. Prod. 349. 
Hab.: Endeavour River, Banks and Solander ( Herb . R. Brown) ; Rockingham Bay ,Dallachy ; 
Islands of Torres Strait. 
The species is widely distributed over East India and the Archipelago. 
Order CYII. PIPERACEAE. 
Flowers hermaphrodite or unisexual, in closely packed spikes or rarely 
racemes, each with a subtending bract often stipitate. Perianth none. Stamens 
2 to 10, inserted on the rhachis or at the base of the ovary. Ovary (except 
in the tribe Saururea >, which is not Australian) 1 -celled, with 1 erect ovule ; 
stigmas 1 to 6, sessile. Fruit a small indehiscent berry. Seed solitary with 
a farinaceous or fleshy albumen. Embryo minute at the upper end. — Herbs 
shrubs or climbers, sometimes succulent, often articulate at the nodes. Leaves 
alternate or rarely opposite or whorled, entire, usually minutely pellucid dotted, 
with or without stipules. Flowers small, the spikes terminal, leaf-opposed or 
rarely axillary. 
The Order is generally distributed over the tropical and subtropical regions of the New and 
the Old World, consisting chiefly of the two Australian genera, both of which range over the 
general area of the Order. — Benth. 
Anthers of 2 distant cells placed back to back, each opening in 2 valves. 
Stigmas 2 to 4, usually 3. Shrubs trees or climbers, rarely tall herbs ... 1. Piper. 
Anther-cells confluent, the whole anther opening in 2 valves. Stigma tufted. 
Herbs often small 2. Peperovia. 
The spurious dissepiment which so frequently divides the young anther-cell more or less 
perfectly into two is usually very prominent in Piperace®, and the anther is therefore sometimes, 
described as 4-celled in Piper, and 2-celled in Peperomia.— Benth. 
1. PIPER, Linn. 
(From the Bengalese name.) 
(Potomorphe and Macropiper, Miq.) 
Flowers unisexual or hermaphrodite, the subtending bract peltate or adnate. 
Stamens in the Australian species 2 or 3 ; anthers of 2 distinct ceils placed 
back to back, each opening outwards in 2 valves. Ovary 1-celled, with a single 
ovary. Stigmas 3, or in species not Australian 2, 4 or more. Berries sessile or 
stipitate. — Shrubs trees or woody climbers, rarely tall herbs, the branches
