Lords-and-ladies - Arum maculatum

Notes: The photo above shows the inflorescence with the spathe partially removed, which allows us to see inside. The dark brown part is called the spadix. Moving down we see the sterile part of the flower, which are hair like structures. These are followed by the male part, moving further down there are some more hairs and finally at the bottom, the female part of the flower. The hairs are used to trap the flies that are attracted to it due to its colouration and higher temperature. The flies get a dusting of pollen from the male part and deliver pollen from other Arum maculatum to the female part, before getting out of the plant to carry on the pollination.
ETA: Have just been chatting to Lucy from Loose and Leafy, she mentioned that another cool name for this plant is 'Jack in the Pulpit'.
