Looks like a crab spider. Lots of photos on the web, mostly of yellow
ones, which are the ones I see most often.
Here's what Wikipedia says:
<Crab spiders make up the Thomisidae family of the Araneae order. They
are also commonly called "flower spiders" because they are most often
found on flowers, lying in ambush for prey. Crab spiders do not build
webs to trap prey, but are active hunters much like the jumping spiders
(Salticidae).
They are called crab spiders because of their first two pairs of legs,
which are held out to the side giving them (with their flattened,
angular bodies) a crab-like appearance. Also, like crabs, these spiders
move sideways and backwards more easily than forwards.
......
The spiders of Thomisidae are not known to be harmful to humans. Spiders
of an unrelated genus, Sicarius, also resemble crabs (and are sometimes
referred to as "crab spiders"). Sicarius spiders, close cousins to the
recluse spiders, are highly venomous.>
