Trolley 665

Trolley 665, a small trolley from the M&S food hall, was captured early (by my standards) on Wednesday morning, from the island in the middle of the busy junction at the western end of the market place.

Just the one hardy group on the Wetherspoon's terrace taking coffee with their tobacco.

A trolley captured after I had had occasion to pass the ivy above. New growth the pale green. The thought being that it was in a sunny position and looked as if it was well established, so why were the leaves not growing big, in the way of the ivy growing along the alley leading to the footbridge behind the Sainsbury's store in Kiln Lane? As noticed, for example, at reference 2.

Apart from the sunny position, the only difference that I could see was that the ivy above was growing in a raised bed, which may or may not have been connected to the subsoil and which may or may not have tended to dry out in dry weather.

Turning to Bing, I find references 3 and 4, rather botanical, but from which I gather that there are 15-20 different sorts of ivy, but that sorting out which is which seems to depend largely on their trichomes, which I think is the botanical name for hairs and other small structures attached to leaves and stems. Not something the curious passer-by is going to be able to make much of. So not much further ahead.

PS: I also find that botanists do principal component analysis. Is there no escape?
