Like Menacing Clouds...

Hulthemia petals at 400X seem to forebode stormy weather on the way.


Above are shown the surface cells of a Hulthemia seedling along the junction of the blotch with the rest of the petal.  Some of the cells are very darkly pigmented.

Further from the leading edge of the blotch these deeply pigmented cells (seen at 40X below) may be surrounded by non-blotch cells. 



All of the photos here are of fresh naked petals (no cover slip or preservative was used) to allow for better representation of the surface architecture.  The close-up shots reveal a myriad of color intensities present, reminiscent of a Pointillism work by French artist Seurat.





A more tangential shot of a petal, shown below, is of the Hulthemia seedling described in Heat and Sun Tolerant Blotch.  There is so much texture to the surface that it looks like a million marbles racing down a slope.



Yes, this wannabe botanist scientist is having fun with his new microscope!  :)
