This page has been created for people who want to learn more about plants, especially in the context of their taxonomy (Latin names, etc.). This is by no means an exhaustive list of all available Web resources for a particular genus.
If you like this page, you might also want to visit the Land of the Glandular Trichomes , a microscopic look at plants in the Lamiaceae family. Also, you can see my contribution to the Conservation New England web site, entitled "The Introduction of Non-Native Plants into Massachusetts".

This month's genus:


Subclass: Dicotyledoneae
Superorder: Rosidae
Order: Umbellales
Family: Apiaceae
Number of Species: 3
Root: This genus was named for Johann Ziz, a German botanist in the 19th century.

Plants in the genus Zizia, like most others in the Apiaceae family, bear flowers on distinct umbels, or umbrella-like inflorescences. The Apiaceae family, originally (and often still) known under the name Umbelliferae, was possibly the first family of flowering plants to be recognized by early botanists. There appears to be some confusion between the species Z. aptera and Z. aurea, which are often both referred to as "Golden Alexanders".

Here are a few links to images and descriptions of different Zizia species:
