The UK Guardian has a long article about the theft from Kew Gardens, in January, of the smallest water lily in the world.

Shortly after two o’clock on the afternoon of Thursday, January 9, Nick Johnson, the 43-year-old manager of the conservatory, returned to Kew after spending the morning at a school in east London.

[...]

As usual, he [...] checked on the rarest, and most endangered, plant in the glasshouse, the Nymphaea thermarum, which is the smallest water lily in the world. Unlike some of the valuable orchids and cacti in the conservatory, which are kept behind glass screens, the tiny water lilies, whose white flowers measure less than 1cm across, were on open display, albeit in a relatively inaccessible position near the foot of a concrete bridge. There were 24 planted out in the mud. Today, Brokensha counted 23 – and a hole where the 24th had been. (Source)

Why would someone steal a flower? Maybe he was done with fish.
