toxic pollen?

[carol ann]

Hi out there!
Does anyone know of Screwbean mesquite (Prosopsis pubescens) having pollen toxic to bees?
Was brought to my attention that in a 'local' gardening resource book, stated that the pollen of this specific plant, not all mesquite, was actually toxic to bees.
Thanks.
