Purple flowers!
For example, if you scout around you might find constellations of little purple flowers. These belong to
Utricularia resupinata.
I recall having seen these plants in flower here when I had visited nearly two decade ago.
(This following will mean something only to long-term photographers)

On that long-ago trip I had shot two rolls of Utricularia resupinata
here, but I had set the film speed on my
camera wrong, i.e., ASA 64 instead of ASA 200. Oops! So my mission with this plant was to right that ancient wrong.</OG>
