Vetches and passion flowers have modified some of their leaves and converted them into tendrils. These grope around in space until they touch the stem of another plant and swiftly coil around it. The tendrils then coil and pull the plant up towards the sunlight.

A terrestrial orchid from the Colombian Andes, Anguloa uniflora is about 18 to 24 inches tall with thin pleated leaves above conical pseudobulbs. The large, fragrant, creamy-white, waxy flower grows on a single stem that rises from the base of the pseudobulbs. The lip is hinged and, when insects enter to remove nectar, they are shoved against the column to help in pollination.

The name ‘Cuckoo-Pint’ may seem strange enough, but becomes all the weirder when one learns that ‘Pint’ is derived from ‘Pintle’, an old word for penis (and a reference to the phallic spadix inflorescence). Other names include Lords-and-Ladies, Cows-and-Bulls, and Naked Boys.
