Oxalis tropaeoloides

In the younger one there was a vague region, where the cells were slightly smaller than those above or below—

In the older one with a clearly well developed true leaf (& cotyledons 3.4 mm long) there is what looks like the ghost of a pulvinus close to the lamina. There are distinct small pulvinus-cells .015 to .024 mm in length, but they are not arranged continued in a regular band across the petiole: in the central line of this petiole there are 3 or 4 in a row lengthways but towards the edges of the petiole, the pulvinus disappears, & it can be seen where it only consists of 1 or 2 cells. I suppose this gives it a ghostly look as the cells at the centre catch ones eye at once as a narrow bit of pulvinus which disappears as the eye follows the line across petiole
