I see your botany skills rival my own lazy. 
There is a reason I don’t post in this thread often. I’d have to know what I’m looking at! 
Guys! Tsk! Tsk! Tsk! You also have to recognize that not every blooming plant is favored by honey bees or that certain plants will only be worked if there is nothing else. Just because it blooms doesn't mean a honey bee will even come near it. Remember, honey bees prefer the highest sugar concentration that they can find when it comes to nectar collection. Yellow sweet clover is starting to bloom here. That's 52% sugar concentration! You know when that starts blooming you better have your supers in place! Start by looking to see if honey bees are working a particular species. If they are, do your research and figure out what it is.
The best honey bee book out there, in regards to nectar and pollen sources, is Peter Lindner's
Garden Plants for Honey Bees. It's worth the $30-$35 and will help you with identification. Chapters are broken down into months. He rates the attractiveness of the nectar and the pollen to the honey bee. Lindtner includes a picture of the blooms and a written description of the pollen color so you know what you are seeing in the bee's pollen baskets. The calendar aspect of it is very general. There can be quite a difference in bloom period across the country. I highly recommend this book.
OK. I'm done. I will get down off my soap box.
