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 should also visit the Land of the Glandular Trichomes , a microscopic look at plants in the Lamiaceae family.

This week's genus:

Zostera - Eel Grass

Subclass: Monocotyledoneae
Superorder: Alismatidae
Order: Najadales
Family: Zosteraceae
Number of Species: 12
Root: From the Greek "zoster", meaning girdle, apparently a reference to the long leaf blades.

Plants in the genus Zostera are all marine species, and live their entire lives submerged in salt water. Eel grass is an important component of marine ecosystems, and several species of both plants and animals depend on it for survival.

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