2PiperalesA group of herbs, shrubs, and small trees found primarily in the tropics.Piperales have tiny flowers that have no petals at allThe miniscule flowers are densely clustered in long spikes.Many species are aromatic, producing fragrant or spicy smells.
3PiperaceaeHabit: woody-volubilis ( liana ) plants (herbs, shrubs and small trees) native to tropics. comprising 10 genera and 1,400 to 2,000 species.Leaves: entire, single, alternate or rarely opposite or whorled,Inflorescence: rat-tail like spikes.Flower: bisexual, or less commonly unisexual, minute, lack perianth (apetalous. )Fruit: berry or drupe.Other: they have secretary tissues consist of cells containing volatile oil
4Piper nigrum L.Habit: herbaceous woody-volubilis liana, native to tropicsLeaves: entire, ovate, single, alternate, petiolate, acuminateInflorescence: spicum, opposite with leavesFlower: apetalous, bractateFruit: bacca
8Piper cubeba L.The dried cubeb berries contain essential oil consisting monoterpenes (sabinene 50% and α-thujene) and sesquiterpenes (caryophyllene, α- and β-cubebene, cadinene), the oxides 1,4- and 1,8-cineole and cubebol
9Piper mythysticum( Kava ) Habit: shrub, with fleshy erect stemLeaves: flate, petiolate, cordate at the base and acuminate at the tipInflorescence: spicumFruit: bacca
10ORDER Aristolochiales There are about 600 to 700 species, most of them in the genus Aristolochia ( 500 spp.), and most of the rest in Asarum ( 100 spp.).They may grow as climbing vines, as short creeping herbs, and a few are shrub-like.Members of this group have attractive leaves and flowers,
11Aristolochiaceae Habit: perennial Shrubs, or lianas, or herbs Leaves: simple, entire (usually), or dissected; alternate, spiral, flat, petiolate, aromatic,Flowers: solitary, or aggregated, small to large, regular to very irregular, tricyclic to pentacyclic.Fruit: a capsule (usually), or a berry, or a nut.
