Pithecoctenium is a Bignoniaceae genus of some 20 species of climbing shrubs occurring in the Caribbean and Tropical South America from Brazil to Mexico. Leaves are opposite with 3 entire and stalked leaflets, the terminal leaflet sometimes being modified into a tendril. The genus has distinctive prickly capsules.[1]
Pithecoctenium crucigerum (L.) A.H. Gentry has become an invasive weed in Australia.[2] Chemical investigation of methanol extracted from this species yielded the iridoid glycoside theviridoside along with five phenylethanoid glycosides (verbascoside, isoverbascoside, forsythoside B, jionoside D and leucosceptoside B), these last all active against DPPH.[3]
'Pithecoctenium' translates to 'Monkey Comb'.
