Plant Biology / Plant Sciences 102: California Floristics
Family Recognition Quizzes
Think you can recognize the most common plant families?
Try it out! Set up your own taxonomy quiz by ...
... choosing the plants.
This quiz will let you pick and choose the families you would like to see from a list of around 100 easily recognized plant families.
... choosing the labs.
If you're currently taking PLB102, you may find it easier to use this quiz, which lets you select the families in the order they are presented in class.
5/28/12 - More monocots! We've now added new photos for Arecaceae, Cyperaceae, Juncaceae, and Typhaceae. We've also thinned out the photos for Poaceae so they don't dominate everything else. The quiz by PLB 102 lab now has images for all of the families covered in Labs 2 through 8. (Only one lab to go and we'll have the complete set!) As always, be sure to hold down the shift key and reload, so you get the newest plantlist.
5/19/12 - After trimming down the pool of photos for Asteraceae last week, we had to do the same thing for Orchidaceae this week. We also added about 50 new photos spread across 5 monocot families. The quiz by PLB 102 lab now has images for all of the families covered in Labs 2 through 7. Be sure to hold down the shift key and reload, so you get the newest plantlist.
5/14/12 - The sunflower family was over-represented in our photo library, and it was throwing off the balance of families in the quizzes, so we've now taken out about half of those shots. (Not an easy thing to do, because the family is so photogenic.) If you find that you're still getting too many shots of Asteraceae, try reloading the quiz page while you hold down the shift key. The quiz by PLB 102 lab now has images for all of the families covered in Labs 2, 3, 4, 5, & 6. Happy studying!
5/6/12 - We just added some pictures of Chenopodium and a few related genera. If you're taking the quiz by family, the correct answer for these plants will be "Amaranthaceae" (because that quiz follows the APGIII system). But if you're taking the quiz by PLB 102 lab, then the correct answer will be "Chenopodiaceae" (because that quiz follows the Jepson Manual and what you've learned in class). At this point, all of the families from Labs 2, 3, 4, & 5 are now well-represented in the online quiz, so we hope that this site will help you prepare for the next in-class quiz coming up on 5/8. Good luck!
5/1/12 - While testing the site, we found a small mistake in the family classifications on the quiz. Photos of the genus Aucuba were once in the dogwood family, Cornaceae, but they should have been moved to the silk tassel family, Garryaceae, with the latest APG classifications. The mistake has now been corrected, so be sure to hold down the shift key and reload before you take your next quiz.
4/25/12 - We just added 120 new images to the family recognition quizzes! The new photos cover Anacardiaceae, Campanulaceae, Caprifoliaceae, Garryaceae, Hydrangeaceae, Hypericaceae, Juglandaceae, Limnanthaceae, Orobanchaceae, Phrymaceae, Plumbaginaceae, Polemoniaceae, Portulacaceae, Primulaceae, Sarraceniaceae, and Vitaceae. Give them a look and let us know what you think. We'll be adding more photos for the monocots next week.
Frequently Asked Questions:
How did you choose which families to include in the quizzes?
This site is primarily intended to support the California Floristics course taught at the University of California at Davis, so our first priority is to include the families covered in those labs. Beyond that, we try to include the most common and recognizable families found in North America. If we ever get that set of plants completely covered, we may try to expand our list to include other regions of the world.
What should I do when the quiz starts acting weird?
The most likely problem is that you started the quiz before the database
file had completely loaded. Try holding down the "shift" key while
you reload the page and be sure you wait for everything to finish
loading before you click on "Continue." It might also help to restart
your browser and empty the cache before you start the quiz again.
Where did the photos in these quizzes come from?
Most of the photos were taken in the Davis area by the grad student who built the website. About 25% of the photos come from other amateur photographers scattered around the world. You can read about the contributors on our photo credits page.
